您好,BIN和GPOUT数据手册pin脚功能说明有详细说明。
GPOUT: This pin should not be left floating, even if unused; therefore, a 10-kΩ pullup resistor is recommended. If the device is in SHUTDOWN mode, toggling GPOUT will make the gauge exit SHUTDOWN. It is recommended to connect GPOUT to a GPIO of the host MCU so that in case of any inadvertent shutdown condition, the gauge can be commanded to come out of SHUTDOWN
BIN: A 10-kΩ pulldown resistor should be placed between BIN and VSS, even if this pin is unused. NOTE: The BIN pin must not be shorted directly to VCC or VSS and any pullup resistor on the BIN pin must be connected only to VDD and not an external voltage rail. If an external thermistor is used for temperature input, the thermistor should be connected between this pin and VSS.
您好,EVM板上是默认BIN接电池端的thermistor,The BIN pin should not be shorted directly to VDD or VSS.
