MC33926
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 undervoltage, overcurrent, and overtemperature 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). An inverted input changes the IN1 and IN2 inputs to LOW = true logic.
Features
- 5.0 to 28 V continuous operation (transient operation from 5.0 to 40 V)
- 225 m 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
- 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...
