Product details

Single-cell Li-ion charger with I2C programmability

It delivers a constant charging current up to 1.25A and supports a maximum battery pack voltage of 4.44V — the standard termination for a single Li-ion cell. Charge current, charge timer, and regulation voltage are all programmable via I2C, giving the system designer fine control over the charging profile without external resistor dividers. Built-in fault protection covers over-temperature and over-voltage conditions.

Housed in a 20-bump DSBGA (20-DSBGA) package, the BQ24150YFFR is a surface-mount device intended for compact portable designs.
