Maxim MAX5925AEUB+

Контроллер горячей замены1Тайм-аут неисправности, запертая неисправность, UVLO

Overview

The MAX5924/MAX5925/MAX5926 1V to 13.2V hot-swap controllers allow the safe insertion and removal of circuit cards into live backplanes. These devices hot swap supplies ranging from 1V to 13.2V provided that the device supply voltage, VCC, is at or above 2.25V and the hot-swapped supply, VS, does not exceed VCC.

The MAX5924/MAX5925/MAX5926 are available with open-drain PGOOD and/or active-low PGOOD outputs. The MAX5925/MAX5926 also feature a circuit breaker with temperature-compensated RDS(ON) sensing. The MAX5926 features a selectable 0ppm/°C or 3300ppm/°C temperature coefficient. The MAX5924 temperature coefficient is 0ppm/°C and the MAX5925AEUB temperature coefficient is 3300ppm/°C. Autoretry and latched fault-management configurations are available (see the Selector Guide in the full data sheet).
