MCU
The 33886 is a monolithic H-Bridge ideal for
fractional horsepower DC-motor and bidirectional 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.

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 °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.
