17511A SIMPLIFIED APPLICATION DIAGRAM
DESCRIPTION
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 RDS(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).
