Freescale Semiconductor
Technical Data
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
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.
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.
