| Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MPC17529 Rev 1.0, 03/2004 Advance Information 0.7 A Dual H-Bridge Motor Driver with 3.0V/5.0V Compatible Logic I/O The 17529 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar step motors and/or brush DC-motors (e.g., cameras and disk drive head positioners). The 17529 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible logic). The device features on-board charge pump, as well as built-in shoot-through current protection and an undervoltage shutdown function. The 17529 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17529 has a low total RDS(ON) of 1.2 (max @ 25C). The 17529's low output resistance and high slew rates provide efficient drive for many types of micromotors.

SYSTEM/APPLICATION INFORMATION INTRODUCTION The 17529 is a monolithic dual H-Bridge ideal for portable electronic applications to control bipolar step motors and brush DC motors such as those found in camera len assemblies, camera shutters, optical disk drives, etc. The 17529 operates from 2.0 V to 6.8 V, providing dual H-bridge motor drivers with parallel 3.0 V- or 5.0 V-compatible I/O. The device features an on-board charge pump, as well as built-in shoot-through current protection and undervoltage shutdown. The 17529 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The MOSFETs comprising the output bridge have a total source + sink RDS(ON) 1.2 . The 17529 can simultaneously drive two brush DC motors or, as shown in the simplified application diagram on page 1, one bipolar step motor. The drivers are designed to be PWM'ed at frequencies up to 200 kHz. FUNCTIONAL TERMINAL DESCRIPTION Freescale Semiconductor, Inc... VDD The VDD terminal carries the logic supply voltage and current into the logic sections of the IC. VDD has an undervoltage threshold. If the supply voltage drops below the undervoltage threshold, the output power stage switches to a tri-state condition. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operation according to the established condition of the input terminals. VM1 and VM2 The VM terminals carry the main supply voltage and current into the power sections of the IC. This supply then becomes controlled and/or modulated by the IC as it delivers the power to the loads attached between the output terminals. All VM terminals must be connected together on the printed circuit board. C1L and C1H, C2L and C2H These two pairs of terminals, the C1L and C1H and the C2L and C2H, connect to the external bucket capacitors required by the internal charge pump. The typical value for the bucket capacitors is 0.1 F. IN1A, IN1B, IN2A, and IN2B These logic input terminals control each H-Bridge output. IN1A logic HIGH = OUT1A HIGH. However, if all inputs are taken HIGH, the outputs bridges are both tri-stated (refer to Table 1, Truth Table, page 7). CRES The CRES terminal is the output of the internal charge pump. Its output voltage is approximately three times the VDD voltage. The VCRES voltage is power supply for internal predriver circuit of H-Bridges. OE The OE terminal is a LOW = TRUE enable input. When OE = HIGH, all H-Bridge outputs (OUT1A, OUT1B, OUT2A, and OUT2B) are tri-stated (high-impedance), regardless of logic inputs (IN1A, IN1B, IN2A, and IN2B) states. PGND Power ground terminals. They must be tied together on the PCB. OUT1A, OUT1B, OUT2A, and OUT2B These terminals provide connection to the outputs of each of the internal H-Bridges (see Figure 1, 17529 Simplified Internal Block Diagram, page 2). LGND Logic ground terminal. 17529 8 MOTOROLA ANALOG For More Information On This Product,INTEGRATED CIRCUIT DEVICE DATA Go to: www.freescale.com Freescale Semiconductor, Inc. APPLICATIONS Typical Application Figure 5 shows a typical application for the 17529. When applying the gate voltage to the CRES terminal from an external source, be sure to connect it via a resistor equal to, or greater than, R = VC /0.02 . G The internal charge pump of this device is generated from the VDD supply; therefore, care must be taken to provide sufficient gate-source voltage for the high-side MOSFETs when VM >> VDD (e.g., VM = 5.0 V, VDD = 3.0 V), in order to ensure full enhancement of the high-side MOSFET channels.
