ISL6172 - Dual Low Voltage Hot Swap Controller

Datasheet Summary

Description

PIN 1 2 3 NAME SNS1 VO1 SS1 FUNCTION Current Sense Input Output Voltage 1 Soft-Start Duration Set Input DESCRIPTION This pin is connected to the current sense resistor and control MOSFET Drain node.

Features

  • a charge pump for driving external N-Channel MOSFETs, regulated current protection and duration, output undervoltage monitoring and reporting, optional latch-off or retry response, and adjustable soft-start. The current regulation level (CR) for each rail is set by two external resistors and each CR duration is set by an external capacitor on the TIM pin. After the CR duration has expired the IC then quickly pulls down the associated GATE(s) output turning off its external FET(s). The ISL6172 of.

® ISL6172 Data Sheet June 2004 FN9158 Dual Low Voltage Hot Swap Controller This IC targets dual voltage hot swap applications across the +2.5V to +3.3V bias supply voltage range with a second lower voltage rail down to less than 1V. It features a charge pump for driving external N-Channel MOSFETs, regulated current protection and duration, output undervoltage monitoring and reporting, optional latch-off or retry response, and adjustable soft-start. The current regulation level (CR) for each rail is set by two external resistors and each CR duration is set by an external capacitor on the TIM pin. After the CR duration has expired the IC then quickly pulls down the associated GATE(s) output turning off its external FET(s).
