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. The part operates over the industrial temperature range of -40°C to 85°C, making it suitable for outdoor handhelds, medical monitors, and industrial IoT nodes that see temperature swings. ## 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. That exposed pad is the primary thermal path; without a proper via stitch to a ground plane, the junction temperature will rise quickly under continuous charge current. 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 The LTC4053EMSE-4.2#TRPBF carries an active product status. The part is ROHS3 compliant.
