Product details

1-cell Li-Ion charger in 8-SOIC

The LTC4002ES8-4.2#PBF is a constant-current programmable charger IC from Analog Devices, designed to charge a single-cell (1-cell) lithium-ion battery pack to a target of 4.2V. Charging current is set by an external resistor — the IC itself regulates a constant current until the cell reaches its float voltage, then terminates the charge based on a programmable timer (the only programmable feature on this part). The maximum supply voltage is 22V, giving headroom for common 5V or 12V input rails without an external pre-regulator in many portable and embedded designs.

Temperature grade and board-fit

The tube packaging means the ICs ship in anti-static tubes for pick-and-place or bench assembly.

RoHS3 compliant (ROHS3), so it meets the latest EU restriction-of-hazardous-substances directive for lead-free assembly.
