17517 Simplified Application Diagram
1.0 A 6.8 V Dual Motor Driver IC
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 R
DS(ON)
totem-pole output MOSFETs (0.46
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 V-
compatible 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 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.
This device contains an integrated charge pump and level shifter (for gate
drive voltages), integrated shoot-through current protection (cross-conduction
suppression logic and timing), and undervoltage detection and shutdown
circuitry.
The 17517 has four operating modes: Forward, Reverse, Brake, and
Tri-Stated (High Impedance).
