Five/Six Channel Push/Pull I/O Expander General Description
The AAT4296/98 SmartSwitch is a member of AnalogicTech's Application Specific Power MOSFETTM (ASPMTM) product family. The AAT4296/98 is comprised of five/six push/pull output switches that gate each respective output between a common input supply and ground. This device is targeted for I/O expansion applications, but can also be used for a combination of general purposes to simplify power switching with an off state load discharge. The AAT4296/98 operates over an input voltage range of 1.8V to 5.5V, making it ideal for batterypowered applications. The state of each output channel is controlled with a single GPIO via the EN/SET pin using AnalogicTech's Simple Serial ControlTM (S2CwireTM) interface. When EN/SET is pulled to logic high, the device is enabled and consumes 3A of typical quiescent current. In the off state, each output is pulled low to ground to affect a logic low state for I/O expander or power switching applications; this circuit will act as a load discharge function to rapidly turn off a load circuit. Rated over the -40C to +85C temperature range, the AAT4296 is offered in a Pb-free 8-pin SC70JW package, and the AAT4298 is offered in both a Pbfree 10-pin SC70JW and a Pb-free 12-pin TSOPJW package.

Functional Description
The AAT4296/98 is comprised of five/six push/pull output slew rate limited load switches primarily targeted for microcontroller general purpose input/output (I/O) expansion applications. Each push/pull output is supplied by the common VCC input and is controlled via the digital EN/SET input pin. When a given output is enabled, the voltage source applied to the VCC pin is then switched to the respective output. The high-side P-channel MOSFET transistor has a typical on resistance (RDS(ON)) of 3 when operating from a 3.6V supply.
When a respective output is disabled or turned off, the given output pin is then connected to ground through a low side N-channel MOSFET with a typical on resistance (RDS(ON)) of 2. This circuit architecture affects a simple logic control with the high level based on the applied VCC. For the AAT4296, this creates a 1-to-5 I/O expander, and for the AAT4298 this creates a 1-to-6 I/O expander. Both the AAT4296 and AAT4298 have been designed to operate with an input voltage range of 1.8V to 5.5V, making them ideal for battery-powered applications.

Five/Six Channel Push/Pull I/O Expander
These devices may also be used for load switching applications, as well as I/O expansion. Since the VCC is gated to each output through a slew rate limited low on-resistance switch, they are ideal for controlling applications circuits with light load current requirements. Such applications could include simple LED function indicator lamps, RGB LED fashion lighting, audio and RF circuits, or any other system with a power requirement that does not exceed the thermal dissipation limits of the load switch and device package. Each device push/pull output may be represented by the following circuit and simplified equivalent model (Figures 1 and 2):
VCC
AAT4296/98
Control
OUT
The state of each output is controlled via the EN/SET pin using AnalogicTech's S2Cwire interface. To enable a respective switch, a series of clocked pulses should be applied to the EN/SET pin. The number of pulses clocked will determine the switch configuration based on the truth table shown in Table 1. At the end of the serial pulse data set, the EN/SET set pin should be held high to then latch the clocked data and enable the desired switch configuration. When the device is enabled with the EN/SET held to a logic high state, the device quiescent current consumption will typically increase to 3A and normal ambient room temperatures. If output sequencing of the switches is not necessary, all of the outputs will be switched on simultaneously on the first rising edge of the EN/SET pin by simply pulling the EN/SET to a logic high level. The default switch position for one clock pulse is all switches "on." However, if output sequencing is desired, a series of pulses on the EN/SET pin will set the outputs to the desired state (refer to Table 1 for output settings). The AAT4296/98 offers two different options when the switches are in the off state. For applications with an active pull down or auto-discharge requirement, the internal N-channel switch will connect the output node to ground with a series resistance of 2.

The ON/OFF state of the output is controlled by the EN/SET serial data input. An internal control counter is clocked on the rising edge of the EN/SET pin and is decoded into the 32/64 possible states (see Table 1).

Five/Six Channel Push/Pull I/O Expander
The S2Cwire interface relies on the number of rising edges of the EN/SET pin to address and load the registers. S2Cwire latches data or address after the EN/SET pin has been held high for time TLAT. The interface records rising edges of the EN/SET pin and decodes them into 32 (for AAT4296) or 64 (for AAT4298) different states, as indicated in Table 1. There are 32 (for AAT4296)/ 64 (for AAT4298) different sequences for controlling individual turn-on/turn-off of each switch. The counter can be clocked at speeds up to 1MHz, such that intermediate states are not visible. Alternatively, the EN/SET clock pulses may be entered one at a time for desired setting. The first rising edge of EN/SET enables the IC and turns all the switches ON. Once the final clock cycle is received, the EN/SET pin is held high to maintain the device setting. The device is disabled 500s (TOFF) after the EN/SET pin transitions to a logic low state.

Applications Information
The AAT4296 and AAT4298 have been designed so that no external parts are required for the device to function as a general purpose I/O expander. Such external parts could include bypass capacitors, or pull-up or pull-down resistors. For applications which may use some or all of the output to switch light load current levels to application circuits, good engineering practice would dictate the use of small bypass capacitors place on the VCC input and each output which is being used to conduct current to a load. The use of small ceramic capacitors between the input and output nodes to ground will aid in reducing line and load transient response effects. Refer to the application schematic of Figure 4 for an example for placing bypass capacitors.
CIN should be located as close to the device VIN pin as practically possible. There is no specific capacitor equivalent series resistance (ESR) requirement for CIN; however, for higher current operation, ceramic capacitors are recommended for CIN due to their inherent capability over tantalum or aluminum electrolytic capacitors to withstand input current surges from low impedance sources, such as batteries in portable devices.
Output Capacitor
For typical applications where the AAT4696/98 is used for I/O expansion, no output capacitors are required. Many other common applications such as controlling LED indicator lamps in portable products do not require an output capacitor because the end load is not sensitive to device turn-on transient effects. For improved load transient response in systems using the AAT4296/98 for load switching, the addition of a small output capacitor placed between the output pins and ground can have a beneficial effect. A 0.1F ceramic capacitor is suggested as a reasonable value for an output capacitor. Please refer to Figure 4.
Input Capacitor
Typically a 0.1F to 1F capacitor is recommended for CIN in most applications. A CIN capacitor is not required for basic operation; however, CIN is useful in preventing load transient effects from affecting upstream circuits when internal switches are enabled to their respective output load circuits. 12

Five/Six Channel Push/Pull I/O Expander
The output capacitor has no specific capacitor type or ESR requirement. If desired, COUT may be increased to a value greater than 0.1F without limit to accommodate any load transient condition without adversely affecting the device turn-on slew rate time. Constants for the AAT4296 and AAT4298 are maximum junction temperature, TJ(MAX) = 125C, and package thermal resistance, JA = 120C/W. Worstcase conditions are calculated at the maximum operating temperature, where TA = 85C. Typical conditions are calculated under normal ambient conditions, where TA = 25C. At 25C ambient, the AAT4296 is capable of dissipating 440mW of power. If all five channels have 5.0V output, the average current is 121mA per channel. The AAT4298 is capable of dissipating 625mW of power. If all six channels have 5.0V output, the average current is 131.5mA per channel. At 85C ambient, the AAT4296 is capable of dissipating 177.78mW of power. If all five channels have 5.0V output, the average current is 76.5mA per channel. The AAT4298 is capable of dissipating 250mW of power. If all six channels have 5.0V output, the average current is 83mA per channel.

Thermal Considerations
The AAT4296 and AAT4298 are designed to deliver continuous output load currents. The limiting characteristic for maximum safe operating output load current is package power dissipation. In order to obtain high operating currents, careful device layout and circuit operating conditions need to be taken into account. At any given ambient temperature (TA), the maximum package power dissipation can be determined by the following equation:
TJ(MAX) - TA JA
PD(MAX) =

Driving LED Loads
The AAT4296 and AAT4298 can be used to drive LEDs or other applications with light load current requirements. LED applications may include main and sub-LCD display backlighting, camera photoflash applications, color (RGB) LEDs, and infrared (IR) diodes for remotes. In series with LEDs, ballast resistors must be used to limit the LED current. The LED current will vary with supply voltage and LED forward voltage. Most types of LEDs have forward voltage specifications ranging from 2.0V to 5.0V. Calculate the necessary ballast resistor value from the following formula:
(VIN - VF) - RDS(ON) ILED

RLED =
Where: RLED is the resistance of resistor to be placed in series with the LED (). VIN is the input supply voltage to the device (V). VF is the forward voltage of the LED (V). RDS(ON) is the resistance of the switch when it is turned on (). ILED is the desired operating current of the LED (A).
