The device enters thermal regulation at too high an input to output voltage drop and current. Thermal regulation begins reducing current at 125 °C; at 150 °C device shuts off. For thermal calculation, refer to the Thermal Package section of the BQ25173-Q1 800-mA Linear Charger for 1- to 4-Cell Super capacitor data sheet (SLUSF68).
