Product details

The LTC4053EMSE-4.2#TRPBF is a single-cell Lithium Ion battery charger IC from Analog Devices, designed for portable and USB-powered applications. It terminates at a battery pack voltage of 4.2V and uses a constant-current, programmable charge algorithm. The USB interface simplifies connection to standard USB ports or wall adapters. An integrated over-temperature fault protection circuit guards the die during fault conditions.

Package and thermal handling — the exposed pad matters

The LTC4053EMSE-4.2#TRPBF comes in a 10-TFSOP / 10-MSOP package with an exposed pad (0.118", 3.00mm width). The supplier device package is 10-MSOP-EP. The package is surface-mount only. The listed shipping options are Tape & Reel (TR) and Cut Tape (CT), so plan your pick-and-place feeder setup accordingly.

Lifecycle and sourcing — active, no end-of-life signal
