Overvoltage/overcurrent protector with auto-retry for portable rails
The LTC4362CDCB-2#TRMPBF from Analog Devices is an overvoltage and overcurrent protection controller with automatic retry, designed to safeguard downstream circuitry in handheld and mobile devices. It monitors the input supply rail from 2.5 V up to 28 V and draws only 220 µA of supply current, keeping the battery budget intact. When a fault clears, the part reconnects the load without external intervention — useful for battery-powered gear where a latch-off would strand the user. The 8-DFN (2x3 mm) package fits tight PCB layouts typical of portable electronics.
The 2.5 V to 28 V input range covers single-cell Li-ion through multi-cell battery stacks and common USB-C power-delivery voltages. The 220 µA supply current is the part's own draw, not the load current.
