The A81408 is a power management IC that uses a buck or buck/ boost pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage complete with control, diagnostics and protections.
The output of the pre-regulator supplies a:
- 5 V / 100 mA protected linear regulator
- 3.3 V/ 90 mA linear regulator
- 5 V/ 200 mA linear regulator
- 5 V/ 60 mA linear regulator
- 5 V/ 60 mA linear regulator
- Adjustable 600 mA synchronous buck regulator
Designed to supply CAN transceiver, sensor, and microprocessor power supplies in high-temperature environments, the A81408 is ideal for under-hood applications.
Typical Applications:
- Electric Power Steering
- Braking
