3.2.4.

CVDD Bypass Capacitor for VDD Internal Reference Voltage Output

For best performance, a low ESR ceramic capacitor should be used for the100nF bypass capacitor from the VDD

pin to ground.

3.2.5.

RSENSE Output Sensing Resistor

The typical value for the output sensing resistor is 50m

Ω.

3.2.6.

Pull-up Resistors

For proper function of the I

2C™ interface, the SDA pin must be connected to a positive supply (e.g., the VDD pin)

through an external pull-up resistor.

For proper function of the fault-warning signal on the NFLT pin, it must be connected to a positive supply (VDD)

through an external pull-up resistor.
