LT4250LCS8#PBF, Hot-Swap Controller, 18 V to 80 V in, SOIC-8, 0°C to 70°C

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Контроллеры Горячей ЗаменыLT®4250L is an 8-pin, negative 48V Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. Inrush current is limited to a programmable value by controlling the gate voltage of an external N-channel pass transistor. 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. Application includes central office switching, -48V distributed power systems, negative power supply control. • Circuit breaker immunity to voltage steps and current spikes• Programmable inrush and short-circuit current limits• Programmable overvoltage protection• Programmable undervoltage lockout• Power good control output• Bell-core compatible ON/OFF threshold• Supply voltage operating range from 18 to 80V (TA = 25°C)• 8-lead plastic SO package• Temperature rating range from 0°C to 70°C
