17511 0.46 Ω (TYP) H-BRIDGE MOTOR DRIVER IC
The 17511 is a monolithic H-Bridge that is ideal in portable electronic applications to control
various micro DC-motors found in Single Lens Reflex Cameras and Optical Disc Drives (MO, DVD,
and CD).
The 17511 is a 6.8 V H-Bridge motor driver with enable and tri-state bridge control and an
additional output for controlling an external MOSFET via a parallel MCU interface (3.0 V and 5.0 V
compatible logic). The IC can drive various types of micro motors with low loss via parallel drive.
The part uses very efficient drivers designed for PWM control frequency up to 200 kHz for high-
speed drive and independent input/output circuitry.
The 17511 has a low “ON” resistance
of 0.6 Ω (max). The output devices
use an integrated charge pump and
level shifter for gate drive voltages,
with integrated shoot through current
protection circuit and undervoltage
circuit detector. The bridge operates
in four output control modes: For-
ward, Reverse, Brake, and Tri-state
(Open).
CUSTOMER BENEFITS
