Technical Data

5.0 A H-Bridge

33886

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.

H-BRIDGE

A Fault Status output reports undervoltage, short circuit, and

overtemperature 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°C ≤ T_A≤ 125°C, 5.0 V ≤ V+ ≤ 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.

Features

• 5.0 V to 40 V Continuous Operation

• 120 mΩ R_DS(ON)H-Bridge MOSFETs

• TTL/CMOS Compatible Inputs
