Description

The LT4250LCN8 is designed as one kind of 8-pin, negative 48V Hot SwapTM controller that can be used in (1)central office switching; (2)48V distributed power systems; (3)negative power supply control. The pass transistor is turned off if the input voltage is less than the programmable undervoltage threshold or greater than the overvoltage threshold. A programmable current limit protects the system against shorts.

Features of the LT4250LCN8 are:(1)allows safe board insertion and removal from a live 48V backplane; (2)circuit breaker immunity to voltage steps and current spikes; (3)programmable inrush and short-circuit current limits; (4)pin compatible with LT1640L/LT1640H; (5)operates from 20V to 80V; (6)programmable overvoltage protection; (7)programmable undervoltage lockout; (8)power good control output; (9)bell-core compatible ON/OFF threshold.

The absolute maximum ratings of the LT4250LCN8 can be summarized as:(1)supply voltage (VDD-VEE): -0.3V to 100V;(2)DRAIN, PWRGD, PWRGD pins: -0.3V to 100V;(3)SENSE, GATE pins: -0.3V to 20V;(4)UV, OV pins: -0.3V to 60V;(5)maximum junction temperature: 125°C;(6)operating temperature range: 0°C to 70°C;(7)storage temperature range: -65°C to 150°C;(8)lead temperature (soldering, 10 sec): 300°C.
