PRODUCTION DATA
The TPS92205x family enables constant current (CC) / constant voltage (CV) charging operation by configuring UVP pin. For CC charging operation, the device generates a controllable output current controlled by a PWM signal at ADIM/HD pin. If a low-current pre-charge is required, the device can generate a relatively low output current controlled by a low-duty-cycle PWM signal at ADIM/HD pin. CV charging operation is enabled and the output current continuously decreases after VUVP falls below 1.4V. The device stop switching completely after VUVP falls below 1.0V. The device can return to CC charging operation once VUVP rises above 1.4V.
