概述
Description
MAX1651CSA is a Maxim hot‑swap controller that protects a live power rail by driving an external MOSFET. It manages inrush, limits current, and guards against faults to prevent damage during plug‑in/removal.
Key features
- Programmable current limit via sense resistor
- Programmable soft‑start to tame inrush
- Undervoltage lockout (UVLO)
- Overcurrent protection (latch or hiccup)
- Overvoltage protection and thermal shutdown
- Fault/STATUS signals (open‑drain outputs)
- Enable input and wide operating range for power rails
Typical applications
- Server backplanes, telecom power rails, and other systems needing safe plug‑in protection for live supplies.
Note: The CSA suffix denotes a specific package/temperature grade variant of the MAX1651 family; check the datasheet for exact package and electrical details.
