Product details

Single-cell Li-Ion charger with 4.2V termination

The LTC4050EMS-4.2#PBF: Charging current is constant-current programmable, and charge termination is timer-based — no thermistor or cell-voltage taper sensing required. Maximum supply voltage is 10V, and the operating temperature range spans -40°C to 85°C, covering industrial and outdoor battery-powered equipment.

Package and board-fit details

Housed in a 10-lead MSOP (0.118", 3.00mm width) surface-mount package, supplied in Tube format. The supplier device package is 10-MSOP.

Product status is Active, and the part is ROHS3 compliant.

Frequently asked questions

What is the closest functional alternative to LTC4050EMS-4.2#PBF?

The LTC4050EMS-4.1#PBF is the same die in the same package, differing only in the battery termination voltage — 4.1V vs 4.2V. It will drop into the same PCB footprint without layout changes, but the charge voltage threshold changes.
