6.4.6 IO Based Shutdown

The device can shut down upon the assertion of the INT pin (pad C2) when configured via Settings GPIO IO Shutdown and the configuration bit [IO_SHUT] = 1. When the pin is asserted for IO Shutdown Delay, the gas gauge opens its DSG FET, then shuts down once PACK voltage < Charger Present Threshold. If the pin is deasserted or [IO_TIMEOUT] is set and IO Shutdown Timeout expires following activation before PACK voltage < Charger Present Threshold, then the shutdown is stopped and the DSG FET turns back on and returns to the state it was in before the pin was asserted. An active low signal is detected when [IO_POL] = 0. An active high signal is detected when [IO_POL] = 1. An internal pullup is enabled when [IO_PUL_DIS] = 0. The pullup is disabled when [IO_PUL_DIS] = 1. The pin is sampled every 250 ms.
