Note 1: V_IN = 5.0V. All outputs are on. T_A = 25°C unless otherwise specified.
Note 2: When chip temperature reaches 105°C, the IC’s internal thermal limit will maintain this temperature by decreasing the pro-
grammed charge current
Note 3: When chip temperature reaches 140°C, the IC goes into a latched shutdown mode. It stops charging, stops supplying
V_OUT). To resume the charging function, a toggle of V_IN is required.
Note 4: When charging current reaches 1.2A, the IC goes into shutdown, latched mode only toggled V_IN could resume the function.
