All rights reserved. 5.0 A Throttle Control H-Bridge The 33932 is a monolithic H-Bridge Power IC in a robust thermally enhanced package. The 33932 has two independent monolithic H-Bridge Power ICs in the same package. They are designed primarily for automotive electronic throttle control, but are applicable to any low voltage DC servo motor control application within the current and voltage limits stated in this specification. Each H-Bridge in the 33932 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. A load current feedback feature provides a proportional (0.24% of the load current) current output suitable for monitoring by a microcontroller’s A/D input. A Status Flag output reports under-voltage, over-current, and over-temperature fault conditions. Two independent inputs provide polarity control of two half-bridge totem pole outputs. Two independent disable inputs are provided to force the H-Bridge outputs to tri-state (high-impedance off state). Features •8.0 to 28 V continuous operation (transient operation from 5.0 to 40 V) •235 m maximum RDS(ON) at 150 °C (each H-Bridge MOSFET) • 3.0 and 5.0 V TTL / CMOS logic compatible inputs • Output short-circuit protection (short to VPWR or GND) • Over-current limiting (regulation) via internal constant-off-time PWM • Temperature dependant current limit threshold reduction • All inputs have an internal source/sink to define the default (floating input) states • Sleep mode with current draw < 50 µA (each half with inputs floating or set to match default logic states) SFA FBA IN1 IN2 D1 EN/D2 VPWRA CCPA OUT1 OUT2 PGNDA AGNDA MCU 33932 VPWR VDD MOTOR OUT3 OUT4 MOTOR SFB IN4 IN3 FBB D3 EN/D4 PGNDB AGNDB VPWRB CCPB VPWR VDD Figure 1.
