Pin Functional Description
SOURCE (S1, S2, S3) Pins :
Internally connect to the SOURCEs of MOSFETs 1, 2 and 3
respectively.
DRAIN (D1, D2, D3) Pins :
Internally connect to the DRAINs of MOSFETs 1, 2 and 3
respectively.
VOLTAGE SUPPLY (VCC) pin
The internal MOSFETs are fully turned on when the VCC pin
voltage is V
SOURCE voltage relative to GROUND. VCC pin should be
connected to GROUND to turn the MOSFETs off.
GROUND (G) Pin:
This is the ground reference for all the SENZero pin voltages.
