Product details

What this part is and where it fits

The LTC4054XES5-4.2#TRMPBF is a single-cell linear Li-Ion battery charger from Analog Devices. It delivers a programmable constant-current charge up to 800 mA, with a fixed 4.2 V float voltage. The part is housed in a TSOT-23-5 package, surface-mount, and operates across -40°C to 85°C. Typical applications include portable electronics, handheld instruments, and battery-powered IoT nodes where board space is tight and a simple charger with thermal regulation is needed.

800 mA charge current — what it means for the BOM

The 800 mA maximum charge current sets the charge-time floor for a single 4.2 V Li-Ion cell. The constant-current programming is set with a single external resistor.
