It handles a battery pack voltage up to 4.35 V and accepts a supply input up to 13.5 V, making it suitable for USB-C PD or standard 5 V adapters.
On-chip fault protection covers over-current and over-voltage events, reducing external supervisor circuitry.
The supplier device package is 24-WQFN (4x4).
It is designed for single-cell Li-Ion or Li-Polymer battery charging in portable devices, IoT endpoints, and handheld instruments that use a USB input for power.
Yes, the battery chemistry covers both Li-Ion and Li-Polymer, and the number of cells is 1.
The charge current is constant and programmable via an external resistor or I2C (depending on the variant); the device supports programmable current as a feature.
