The device will automatically terminate charging once the charge current reaches ITERM, which is programmable through I2C.
After termination the charger will operate in high impedance mode, disabling the BATFET to disconnect the battery. Power is provided to the system (PMID) by IN supply as long and VIN > VUVLO and VBAT+VSLP < VIN < VOVP.
Termination is only enabled when the charger CV loop is active in fast charge operation. No termination will occur if the charge current reaches ITERM while VINDPM or DPPM is active as well as the thermal regulation loop. Termination is also disabled when operating in the TS WARM region. The charger only goes to termination when the current drops to ITERM due to the battery reaching the target voltage and not due to the charge current limitation imposed by the previously mentioned control loops.
