33886_11 Overview

TTL / CMOS Compatible Inputs PWM Frequencies up to 10 kHz

Freescale Semiconductor
Technical Data
Document Number: MC33886
Rev 9.0, 4/2011
5.0 A H-Bridge
The 33886 is a monolithic H-Bridge ideal for fractional horsepower
DC-motor and bi-directional thrust solenoid control. The IC
incorporates internal control logic, charge pump, gate drive, and low
R
DS(ON)
MOSFET output circuitry. The 33886 is able to control
continuous inductive DC load currents up to 5.0 A. Output loads can
be pulse width modulated (PWM-ed) at frequencies up to 10 kHz.
A Fault Status output reports under-voltage, short-circuit, and
over-temperature conditions. Two independent inputs control the two
half-bridge totem-pole outputs. Two disable inputs force the H-Bridge
outputs to tri-state (exhibit high-impedance).
The 33886 is parametrically specified over a temperature range of
-40

28 V. The IC can also be operated
up to 40 V with derating of the specifications. The IC is available in a
surface mount power package with exposed pad for heatsinking.
