5 A charge current and 14 V supply ceiling
Rated for a maximum charge current of 5 A, this single-cell charger supports fast charging for Li-Ion and Li-Polymer battery packs in portable equipment — the 5 A figure is the peak current the internal power stage can deliver to the battery under programmed charge conditions. The maximum supply voltage of 14 V allows the device to operate from standard USB adapters, 5 V wall chargers, and higher-voltage input sources such as 12 V regulated rails, provided the input stays within the absolute maximum rating.
I²C programmability and fault protection
An I²C serial interface (alongside USB detection logic) gives the host microcontroller control over charge current, termination threshold, input current limit, and timer settings — the charger is not a fixed-function part but a configurable power management IC. Built-in fault protection covers over-current and over-temperature conditions, shutting down the power stage before the die or external components exceed safe limits.
