Technical Data
1.0 A 6.8 V H-Bridge Motor
Driver IC
The 17511A is a monolithic H-Bridge designed to be used in
portable electronic applications to control small DC motors or bipolar
step motors. End applications include head positioners (CDROM or
disk drive), camera focus motors, and camera shutter solenoids.
The 17511A can operate efficiently with supply voltages as low as
2.0 V to as high as 6.8 V. Its low R
DS(ON)
H-Bridge output MOSFETs
(0.46
typical) can provide continuos motor 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.
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 17511A has four operating modes: Forward, Reverse, Brake,
and Tri-Stated (High Impedance).
