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 R_DS(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)
