Pin Symbol Pin type Function

TMP3

Temperature sensor 3. If not used connect pin to GND. If TMP3 is disabled, the pin

can be used as 0 to 2 V auxiliary ADC miscellaneous pin.

GND

Local GND of CSC (cell supervision circuit) device

TMP2

Temperature sensor 2. If not used connect pin to GND. If TMP2 is disabled, the pin

can be used as 0 to 2 V auxiliary ADC miscellaneous pin.

TMP1

Temperature sensor 1. If not used connect pin to GND. If TMP1 is disabled, the pin

can be used as 0 to 2 V auxiliary ADC miscellaneous pin.

TMP0

Temperature sensor 0. If not used connect pin to GND. If TMP0 is disabled, the pin

can be used as 0 to 2 V auxiliary ADC miscellaneous pin.

TMP_GN

Temperature sensor reference. This pin can be connected to local GND.

PWM1

PWM output channel 1. This pin also has a general purpose input/output function.

If not used connect pin to GND.

PWM0

PWM output channel 0. This pin also has a general purpose input/output function.

If not used connect pin to GND.

GND

Local GND of CSC device (cell supervision circuit).
