Freescale Semiconductor, Inc. MOTOROLA Document order number: MPC17517 Rev 1.0, 03/2004 SEMICONDUCTOR TECHNICAL DATA Advance Information 17517 1.0 A 6.8 V Dual Motor Driver IC Freescale Semiconductor, Inc... The 17517 is a monolithic triple totem-pole-output power IC designed to be used in portable electronic applications to control small DC motors and solenoids. The 17517 can operate efficiently with supply voltages as low as 2.0 V to as high as 6.8 V. Its low RDS(ON) totem-pole output MOSFETs (0.46 Ω typical) can provide continuos drive currents of 1.0 A and handle peak currents up to 3.0 A. It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 Vcompatible logic. The device can be pulse width modulated (PWM-ed) at up to 200 kHz. 1.0 A 6.8 V DUAL MOTOR DRIVER IC The 17517 can drive two motors in two directions one at a time or drive one motor in two directions and one solenoid with synchronous rectification of freewheeling currents one at a time. Two-motor operation is accomplished by hooking one motor between OUTA and OUTB and hooking the other motor between OUTB and OUTC. Motor plus solenoid operation is accomplished by hooking a motor between OUTA and OUTB and a solenoid between OUTC and GND.

SYSTEM/APPLICATION INFORMATION Freescale Semiconductor, Inc... INTRODUCTION The 17517 is a triple totem-pole output H-Bridge power IC designed to drive small dc motors used in portable electronics. The 17517 can operate efficiently with supply voltages as low as 2.0 V to as high as 6.8 V, and provide continuos motor drive currents of 1.0 A while handling peak currents up to 3.0 A. It is easily interfaced to low cost MCUs via parallel 3.0 V- or 5.0 Vcompatible logic. The device can be pulse width modulated (PWM-ed) at up to 200 kHz. The 17517 can drive two motors in two directions one at a time; or it can drive one motor in two directions and one solenoid with synchronous rectification of freewheeling currents one at a time. Two-motor operation is accomplished by hooking one motor between OUTA and OUTB, and the other motor between OUTB and OUTC. Motor + solenoid operation is accomplished by hooking a motor between OUTA and OUTB and placing a solenoid between OUTC and GND. Table 1, Truth Table, page 8, describes the operating states versus the input conditions. As shown in Figure 1, 17517 Simplified Internal Block Diagram, page 2, the 17517 is a monolithic triple totem-pole output bridge with built-in charge pump circuitry. Each of the six MOSFETs forming the triple totem-pole output has an RDS(ON) of ≤ 0.6 Ω (guaranteed by design). The IC has an integrated charge pump and level shifter (for gate drive voltages). Additionally, the IC has a built-in shoot-through current protection circuit and undervoltage lockout function. This IC has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). FUNCTIONAL TERMINAL DESCRIPTION OUTA, OUTB, and OUTC These terminals provide the connection to the internal power MOSFET triple-totem-pole H-bridge of the IC. The VM terminals must be connected together on the printed circuit board with as short as possible traces offering as low impedance as possible between terminals. IN1, IN1, EN1, and EN2 GND These terminals are input control terminals used to control the outputs. These terminals are 3.0 V/5.0 V CMOS-compatible inputs with hysteresis. These terminals work together to control OUTA, OUTB, and OUTC (refer to Table 1, Truth Table). Power and signal ground terminal. CRES This terminal provides the connection for the external reservoir capacitor (output of the charge pump). Alternatively, this terminal can also be used as an input to supply gate-drive voltage from an external source via a series current-limiting resistor. The voltage at the CRES terminal will be approximately three times the VDD voltage, as the internal charge pump utilizes a voltage tripler circuit. The VDDRES voltage is used by the IC to supply gate drive for the internal power MOSFETs. VM The two 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 load attached between OUTA and OUTB. MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA 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 µF. VDD This 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.

Typical practice is to provide snubbing of voltage transients by placing a capacitor or zener at the supply terminal (VM) (see Figure 6). When designing the printed circuit board (pcb), connect sufficient capacitance between power supply and ground terminals to ensure proper filtering from transients. For all highcurrent paths, use wide copper traces and shortest possible distances. 5.0 V 5.0 V 17517 VDD VM 5.0 V 5.0 V 17517 VDD VM C1L C1L C1H C1H C2L C2H CRES OUT OUT GND C2L C2H OUT CRES OUT GND Figure 6.
