Dual Low Voltage Hot Swap Controller

Features

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.

• Dual Supply Hot Swap Power Distribution Control to <1V

• Less than 1µs Response Time to Dead Short

• Overcurrent Circuit Breaker Fault Isolation and

Programmable Current Regulation Level Protection

Functions

• Programmable Current Regulation Duration

• Charge Pump Allows the use of N-Channel MOSFETs

• Rail Independent Control, Monitoring and Reporting I/O

• Adjustable Ramp up for Inrush Protection During Turn On

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 offers a

latched output or indefinite auto retry mode of operation.

• Two Levels of Overcurrent Detection Provide Fast

Response to Varying Fault Conditions

• Latch-off or Auto Reset Response to Fault Functions

• Adjustable Current Regulation Threshold as low as 20mV

• QFN Package:

- Compliant to JEDEC PUB95 MO-220

QFN - Quad Flat No Leads - Package Outline

PCB efficiency and has a thinner profile

ISL6172EVAL3 Evaluation Platform

• Pb-free

* Intersil Pb-free products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin plate

termination finish, which is compatible with both SnPb and Pb-free

soldering operations. Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J Std-020B.

Applications

• Power Supply Sequencing, Distribution and Control

• Hot Swap/Electronic Breaker Circuits

• Network Hubs, Routers, Switches
