LTC1694-1
U U U PIN FUNCTIONS VCC (Pin 1):
Power Supply Input. VCC can range from 2.7V
NC (Pin 3):
No Connection. to 6V and requires a 0.1µF bypass capacitor to GND.
SMBus2 (Pin 4):
Active Pull-Up for SMBus. Supply current is typically 45µA when the SMBus or I2C lines are inactive (SCL and SDA are a logic high level).
SMBus1 (Pin 5):
Active Pull-Up for SMBus.
GND (Pin 2):
Ground.
