LTC4211CS8#PBF, Hot-Swap Controller, 2.5 V to 16.5 V in, SOIC-8, 0°C to 70°C

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Контроллеры Горячей ЗаменыLTC4211 is a hot swap controller that allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the gate of an external N-channel MOSFET for supply voltages ranging from 2.5V to 16.5V. This device provides soft-start and inrush current limiting during the start-up period which has a programmable duration. The FB pin monitors the output supply voltage and signals the active-low RESET output pin. The ON pin signal turns the chip on and off and can also be used for the reset function. It is widely used in application such as electronic circuit breaker, hot board insertion and removal (either on backplane or on removable card), industrial high side switch/circuit breaker. • Faster turn-off time because no external gate capacitor is required• SLOW COMP trip to GATE discharging is 20µs typ, dual level overcurrent fault protection• Programmable response time for overcurrent protection (MS)• Programmable overvoltage protection (MS)• Automatic retry or latched mode operation (MS)• User-programmable supply voltage power-up rate• Glitch filter protects against spurious active-low RESET signal• SENSE trip voltage (VCC - VSENSE) is 50mV typ at (slow comparator trips)• SENSE trip voltage is 150mV at (fast comparator trips), operating temperature is 0°C to 70°C• Packaging style is 8-lead plastic SO
