Product details

Hot swap controller with integrated 5.5 A switch

It is designed for general-purpose board-level power management where controlled inrush and fault isolation are needed — typical applications include server backplanes, base station line cards, and industrial power distribution.

Programmable protection and fault handling

The controller integrates a set of programmable features: auto retry, circuit breaker, current limit, fault timeout, and latched fault. This lets the designer tailor the response to overcurrent and short-circuit events — auto retry for transient loads, latched fault for hard shorts that need manual intervention. The UVLO and thermal limit are fixed protections that guard against undervoltage and die overtemperature.
