The BQ25121YFPT from Texas Instruments is a highly integrated battery charge management solution suitable for wearables and IoT applications. This IC supports Li-Ion/Li-Polymer batteries and features a maximum charge current of 300mA.
Key electrical specifications include an input voltage range of 3.4V to 5.5V, with an absolute maximum input voltage of 20V. The battery charge voltage is configurable from 3.6V to 4.65V. Control is managed via an I2C interface, and it offers programmable features for current and fault protection, including over voltage.
The device operates within a temperature range of -40°C to 85°C. It is supplied in a 25-DSBGA package and uses a surface mount configuration. The typical quiescent current (Iq) with the buck converter enabled is 700nA, and it supports a configurable termination current down to 500µA. Power Path Management enables a ship mode quiescent current of less than 50nA for extended shelf life.
