MC33932 Description
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.
MC33932 Key Features
- 8.0 to 28 V continuous operation (transient operation from 5.0 to 40 V)
- 235 mΩ maximum RDS(on) @ TJ = 150 °C (each H-bridge MOSFET)
- 3.0 V and 5.0 V TTL / CMOS logic patible inputs
- Output short-circuit protection (short to VPWR or GND)
- Overcurrent limiting (regulation) via internal constant-off-time PWM
- Temperature dependent current limit threshold reduction
- All inputs have an internal source/sink to define the default (floating input) state
- Sleep mode with current draw < 50 µA (each half with inputs floating or set to match default logic states)
- AEC-Q100 grade 1 qualified
MC33932 Applications
- 8.0 to 28 V continuous operation (transient operation from 5.0 to 40 V)
