22

SNSEN

Sensor Supply Enable Input. The SNSEN pin is an input, which enables the VREF1 and VREF2 supplies. It

allows the control module hardware/software to shut down the sensor supplies.

23

EN

Enable Input. The EN pin is an input, which enables the main switching regulator and all other functions. When

this pin is low, the power supply is in a low quiescent state.

24

VKAM

Keep-Alive (standby) 2.6 V Regulator Output. This is a 2.6 V low quiescent, low dropout regulator for Keep

Alive memory.
