Preliminary Information

6.0 A H-Bridge with Enable

The 33887 is a monolithic H-Bridge with a Sleep Mode feature ideal for

fractional horsepower DC-motor and bi-directional thrust solenoid control. The

IC incorporates internal control logic, charge pump, gate drive, and low

RDS(ON) MOSFET output circuitry. The 33887 is able to control continuous

inductive DC load currents of 6.0 A. Output loads can be Pulse Width

Modulation (PWM) controlled at frequencies to 10 kHz. An internal output

current monitoring circuit provides a proportional (1/375th) feedback current

output for the microcontroller to monitor the output current and provide closed-

loop control.

A Fault Status output reports undervoltage, overcurrent, and

overtemperature conditions. Two independent inputs provide polarity control

of two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge

outputs to tristate (exhibit high impedance).

The 33887 is parametrically specified over a temperature range of -40°C ≤

TA ≤ 125°C, 5.0 V ≤ VPWR ≤ 28 V, and is available in three different surface

mount packages.
