ISL6173

ISL6173 Dual Low Voltage Hot Swap Controller This IC targets dual voltage hot swap applications across the +2.5V to +3.3V (nominal) 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). The ISL6173 offers a latched output or indefinite auto retry mode of operation. Ordering Information PART NUMBER (Note) PART MARKING TEMP. RANGE (°C) PACKAGE (Pb-Free) PKG.
