MPC17533
0.7 A 6.8 V Dual H-Bridge Motor Driver
DESCRIPTION
The 17533 is a monolithic dual H-Bridge power
IC ideal for portable electronic applications
containing bipolar stepper motors and/or brush DC-
motors (e.g., cameras and disk drive head
positioners).
The 17533 operates from 2.0 V to 6.8 V, with
independent control of each H-Bridge via parallel
MCU interface (3.0 V- and 5.0 V-compatible logic).
The device features built-in shoot-through current
protection and an undervoltage shutdown function.
The 17533 has four operating modes: Forward,
Reverse, Brake, and Tri-Stated (High Impedance).
The 17533 has a low total R
DS(ON)
of 1.2
Ω
(max
@ 25°C).
The 17533’s low output resistance and high slew
rates provide efficient drive for many types of
micromotors.
