5.0 A Throttle Control H-bridge
The 33931 is a monolithic H-Bridge Power IC in a robust thermally enhanced package. It is designed primarily for automotive electronic throttle control, but is applicable to any low voltage DC servo motor control application within the current and voltage limits stated in this specification.

THROTTLE CONTROL H-BRIDGE
The 33931 H-Bridge is able to control inductive loads with currents up to 5.0 A peak. RMS current capability is subject to the degree of heatsinking provided to the device package. Internal peak-current limiting (regulation) is activated at load currents above 6.5 A ±1.5 A. Output loads can be pulse-width modulated (PWM-ed) at frequencies up to 11 kHz.
