MC33926 Description
The 33926 is a SMARTMOS monolithic H-bridge power IC 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. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. The 33926 is able to control inductive loads with currents...
MC33926 Key Features
- 5.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V)
- 225 mΩ maximum RDS(on) at 150 °C (each H-bridge MOSFET)
- 3.0 V and 5.0 V TTL/CMOS logic patible inputs
- Overcurrent limiting (regulation) via an internal constant-off-time PWM
- Output short-circuit protection (short to VPWR or ground)
- Temperature dependent 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 (with inputs floating or set to match default logic
- AEC-Q100 grade 1 qualified
MC33926 Applications
- 5.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V)
