LB8632V
Low-Voltage/Low-Saturation Camera Motor Driver
Overview
The LB8632V is a general-purpose camera motor driver IC that supports low-saturation output and low-voltage drive and thus can be used in a wide range of applications. The LB8632V is a miniature thin form-factor IC that provides circuit structures and I/O logic that reduce development times and costs and support reduced lot sizes and end product diversity, despite increasing miniaturization and functionality in application products. Since the LB8632V supports low-voltage operation (starting from 1.2 V) in addition to low-saturation outputs, it provides characteristics that can withstand operation in low-voltage ranges even in 3 V popularly-priced cameras that do not include a step-up circuit. Since the LB8632V supports IIL, control logic can be optimized by using two ICs in parallel, thus allowing even more actuators to be driven with a small number of CPU output ports. Thus the LB8632V can also be used in 6 V top-of-the-line end products.
Features
* 3, 6 V and a wide application range: from popularly priced models to top-of-the-line products The external transistors and the number of ICs (one or two) is determined by the number of IC required motors and actuators. Support for motor standby, forward, reverse and braking control for four motors using only five CPU port lines. This requires two external transistors and two ICs. The LB8632V also provides non-operating mode logic for the operating control signals (the IN input) so that ICs with other functions can be used on the same ports. * Built-in 1 CH low-voltage drive low-saturation, forward/reverse motor drive
IO peak = 3.0 A maximum (t 100 ms: single shot, between OUT1 and OUT2) IO DC = 1.0 A maximum VO sat = 0.45 V typical (at IO = 1 A) Operating voltage range: VB = 1.2 to 7.5 V (VB = VS = VDD = battery voltage) * Built-in low-voltage drive - 0.5 CH forward/reverse motor driver Supports 1.5 CH bridge operation with the use of two external transistors. Also supports LED or solenoid drive with constant-current drive. Operating voltage range: VB = 1.2 to 7.5 V (VB = VS = VDD = battery voltage) * Built-in regulator predriver VCC can be regulated at 1.86 V by connecting the VCC control pin (V CONT) to the reference voltage, V REF (1.36 V). Also, the VCC output voltage can be varied by inputting the CPU D/A output to VCONT. Either the IC itself or only the VCC regulator can be turned on according to the operating mode of each motor. In addition, this function can also be used as a battery check comparator. Operating voltage range: VB = 1.5 to 7.5 V * Three independent power supply line systems The LB8632V supports either single supply specifications (V B = V S = V DD ) or dual supply specifications (battery/step-up supply) by providing a power supply voltage pin (VB), a motor supply pin (VS), and a CPU interface pin (VDD). Also, motor output can be stabilized by taking the motor power supply from the VCC regulator. Support for both CMOS and n-channel open drain outputs from the CPU.

Note: There are no limitations on the magnitude relationships between the VB, VS and VDD supply voltages. 1. Stipulates the total leakage current for VB = VS = VDD when the IC is in standby mode. 2. Stipulates the operating range voltages (for guaranteed functionality) when a single power supply with VB = VS = VDD is used for the DC motor system. 3. Stipulates the operating range voltages (for guaranteed functionality) for the DC motor system VS pin, i.e., the motor power supply. The drive current will be a constant current when VB = VS = 2.0 V or higher. 4. Stipulates the output saturation voltage when either the DC motor driver VB = VS = VDD = 1.8 V and the output current is 600 mA or when VB = VS = VDD = 3.0 V and the output current is 1000 mA. 5. Stipulates the current emitted or accepted by the OUT3P and OUT3N pins. These are constant currents as long as VB = VS = 2.0 V or higher. 6. Stipulates the maximum total current drain for the VB and VS pins for the forward, reverse, or brake operations when drive between the DC motor system OUT1 and OUT2 outputs is used. 7. Stipulates the maximum total current drain for the VB and VS pins for the DC motor driver drive mode standby state. 8. Stipulates the maximum total current drain for the VB and VS pins for the DC motor driver single-sided drive mode, i.e. when a single output from the OUT1, OUT2, OUT3P and OUT3N pins is used. 9. Stipulates the operating voltage range (for guaranteed functionality) for the VREF circuit system. 10.Stipulates the input voltage range for the Vcont pin. When a constant-voltage circuit is formed by adding an external transistor, the voltage is held constant by sensing the VCC pin. 11.Stipulates the reference voltage generated at the VREF pin. 12.Stipulates the ratio of the constant VCC pin voltage value to the VCONT pin input voltage. 13.Stipulates the minimum output voltage for the VCC pin constant voltage output. The voltage will only fall to this value, even when the VCONT pin is set to 0 V. 14.Stipulates the VCC pin stabilized output voltage when the VREF and VCONT pins are connected directly. 15.Stipulates the change in the value of the VCC voltage when VCC is set for constant voltage output and the VB voltage varies from 2 V to 7.5 V. 16.Stipulates the change in the value of the VCC voltage when VCC is set for constant voltage output and the load current varies from 50 mA to 500 mA. 17.Stipulates the VCONT pin input current in the range 0 V VCONT VB - 0.3 V. The value of the VCC output constant voltage can be varied by inputting the CPU D/A output. 18.Stipulates the VB system maximum current drain in all modes when the VCC output has no load. 19.Stipulates the operating voltage range (for guaranteed functionality) for the VDD pin. The VDD pin is connected either to the CPU power supply or VB. 20.Stipulates the input current and allowable leakage current for the control input pins: MD0, MD1, MD2, IN1 and IN2. 21.Stipulates the high and low input voltages for the control input pins: MD0, MD1, MD2, IN1 and IN2. (When input pins are open, they appear to be high-level inputs.) 22.Stipulates the VDD pin current drain when all the for the control input pins (MD0, MD1, MD2, IN1 and IN2) are at the ground level. 23.When the temperature exceeds the stipulated temperature, output current limitation is applied, thus protecting the IC. The stipulated temperature is a design target value and is not tested prior to shipment. 24.Stipulates the lower side output saturation voltage in the OUT1 and OUT2 braking modes (when IO = 600 mA). 25.Stipulates the OUT1 and OUT2 spark killer diode forward voltage (when IF = 600 mA). 26.Stipulates the minimum value of the IB pin sink current.

LB8632V Internal Block Diagram
Wiring Notes 1. Connect both the P-GND and both the VS pins. Although both the P-GND and VS lines are connected internally, both must be connected to provide currents of 1 A or over, or to provide even lower saturation output. However, operation with only one of each of these pairs connected, or with through power supply wiring, is possible. 2. Since large currents flow in the VS and P-GND lines, these lines should be made thicker, and line impedance reducing capacitors should be inserted in the vicinity of the IC. 3. Since S-GND is the ground for the control system, rather than using the same wiring as the P-GND line, it is preferable to connect this pin to the CPU ground line. 4. If the CPU outputs are CMOS outputs, connect VDD to the CPU power supply line and if they are n-channel open drain outputs, connect VDD to the VB pin (battery). However, since VDD is the control input system power supply, it should not be set to the same impedance as the VS line.

LB8632V Sample OUT3P/OUT3N Pin Applications The OUT3P and OUT3N pins support -20 mA (typical) and 20 mA (typical) constant current drive, respectively. Constant current is supported when VB = VS = 2.0 V or higher. A 5 k shunt resistor between the OUT3P pin and ground is included within the IC. Inversely, the OUT3N pin is an open collector pin, and there is no resistor inserted between this pin and the VS pin. A current limiting resistor (resistance maintaining transistor) may be inserted between the OUT3P and OUT3N pins and the external transistors. These pins can also be used for direct LED drive, battery check, or other power supply switching functions.

LB8632V Sample IB and VCC Pin Applications 1. Stabilized Power Supply A low-saturation type stabilized power supply can be formed using an external pnp transistor (2SB815). This circuit has a wide operating voltage range of 1.5 to 7.5 V, and can supply stable power to other pins and loads. This circuit outputs a constant voltage 1.37 times the Vcont input voltage. A 1.86 V constant voltage output can be acquired by directly connecting the VREF reference voltage (1.36 V) to the Vcont pin. * This circuit sets up a constant voltage output of 1.86 V or lower. When R1 is 20 k, the output voltage can be set to any voltage between 0.8 and 1.86 V (typical) by adjusting R2.
* This circuit sets up a constant voltage output of 1.86 V or higher. Taking the manufacturing variation in the IC internal sensing resistor (3.6 to 10 k) into account, the total resistance of the external sensing resistors (R1 and R2) should be about 1 k. Example: A constant voltage output VREG of 3.05 V is acquired when R1 is 360 and R2 is 680 .
* Making the OUT pin output voltage a constant voltage. Connect the OUT pin, which is to be made a constant voltage output, to the VCC pin. When one side of the bridge output is connected, when the connected side is a high-level output the circuit will be a constant voltage drive circuit, and when the other side is a high-level output the circuit will be a saturated drive circuit.
* Generating a hold voltage. This circuit uses a resistance maintaining transistor to lower the VCONT input and generate a hold voltage. A 0.8 V (typical) hold voltage is acquired when R2 is 0 .
* Generating a set constant voltage for different modes. The VCONT input has a high impedance of 1 A maximum, and thus the set constant voltage can be changed as required for each mode by inputting the CPU D/A converter output.

LB8632V 2. Battery Check Tr2 will turn off when the Vcont input voltage, which is VB x
r2 , falls to 0.95 V or lower. r2 + r1
Example: This circuit can check for VB being 2.0 V or lower by setting r1 to be 22 k and r2 to be 20 k. Note that the Tr3 transistor can also use the OUT3N output.
3. Light Measurement Tr2 will turn on when the VCONT input voltage becomes VB x 70% (= 9 k/(3.6 k + 10 k)) or higher. Note that the Tr3 transistor can also use the OUT3N output.
