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
RDS(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 ≤ 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.
