2-channel hot swap controller for 1V-6V rails
The LTC4224CDDB-2#TRMPBF is a 2-channel hot swap controller designed to manage inrush current and supply protection on low-voltage rails from 1V up to 6V. It integrates programmable current limit and slew rate control, plus auto-retry and fault timeout with UVLO, so the controller can autonomously recover from overcurrent events without a system reset.
Supply current and operating range
The controller draws 1.4 mA from the supply rail, a figure that matters for always-on hot-swap circuits where the controller's own consumption adds to the standby budget.
Package and board-fit
Housed in a 10-lead WFDFN with exposed pad, the supplier device package is 10-DFN measuring 3x2 mm.
ROHS3 compliant, meeting the current EU restriction level for lead, mercury, cadmium, and the four phthalates.
