Current Monitor and Accumulator with
Sense Resistor High Side. Connection to high side of internal 38m
must be connected together.
Serial Data Input/Output. SDA is the input/output pin for the I
open-drain output and requires an external pullup resistor.
Serial Clock Input. SCL is used to synchronize data movement on the I
Supply Voltage. Power-supply input.
Do Not Connect
Ground
Sleep Input (Active Low). When taken low, the DS2741 is placed in a low-power sleep state where
all internal circuitry including the I
resets the device and the I
Sense Resistor Low Side. Connection to low side of internal 38m
must be connected together.
Exposed Pad. Can be left floating.
