SEMICONDUCTOR TECHNICAL DATA
33886
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 RDS(ON) MOSFET
5.0 A H-BRIDGE
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 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 ≤ TA ≤ 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.
