This makes it suited for portable devices where the host microcontroller adjusts the charge rate based on battery temperature or input power limits. The charger integrates fault protection against overcurrent, overtemperature, and overvoltage conditions, reducing the need for external supervisory circuitry.
Parametric highlights and package details
The 24-VFQFN Exposed Pad package (4x4 mm body) suits compact portable designs where thermal dissipation through the pad is needed. The battery pack voltage is regulated to 4.2V, and the charge current is constant and programmable — only the current is adjustable via I²C, not the voltage.
