Overview
Description
MAX14931AAWE+ is Maxim Integrated’s automotive‑grade smart power switch family. It provides one or more high‑side switches with integrated protection and a serial control interface (SPI/I2C) to turn loads on/off and configure operation. The AAWE+ suffix denotes automotive temperature grade and a specific WE+ package variant.
Key features (typical, variant dependent):
- Multi‑channel high‑side switches with programmable current limit and soft‑start
- Protection: undervoltage, overcurrent/short‑circuit, overtemperature, reverse battery
- Diagnostics/status reporting for fault conditions
- Flexible sequencing and rail control for safe power ramping
Common applications:
- Automotive body electronics, infotainment power rails, ECUs, gateways
- Other vehicle or industrial systems requiring protected, controllable power delivery
Note: exact channel count, voltage/current ranges, control interface, and package details vary by variant. Check the latest MAX14931AAWE+ datasheet for precise specs.
