Advance Information
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
RDS(ON) totem-pole output MOSFETs (0.46 typical) can provide
continuous 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).
Features
• 2.0 V to 6.8 V Continuous Operation
• Output Current 1.0 A (DC), 3.0 A (Peak)
• MOSFETs < 600 mRDS(ON) @ 25°C Guaranteed
• 3.0 V/5.0 V TTL-/CMOS-Compatible Inputs
• PWM Frequencies up to 200 kHz
• Undervoltage Shutdown
