ZSPM4521 Datasheet
3.2.4. C_VDD 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. R_SENSE Output Sensing Resistor
The typical value for the output sensing resistor is 50mΩ.
3.2.6. Pull-up Resistors
For proper function of the I²C™ 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.
