TI TPS2420RSAR

Контроллер горячей замены1Тепловой предел, UVLO

Overview

The TPS2420RSAR device provides highly integrated load protection for applications up to 20-V. The maximum UV turn-on threshold of 2.9 V makes the TPS2420RSAR well suited to standard bus voltages as low as 3.3 V. The TPS2420RSAR device protects loads, minimizes inrush current, and safely shuts down in the event of a fault. The programmable fault current threshold starts the fault timer while allowing the current to pass to the load uninhibited. The programmable current limit threshold sets the maximum current allowed into the load, for both inrush and severe load faults. Both events use the programmable timer which inhibits all current to the load when it expires.

This device can be programmed to either latch-off or retry in the event of a fault. All of this functionality is packed into a 16-pin 4 × 4 mm QFN package.
