Input Voltage Sensing

The ZSPM2000 supports input voltage sensing for protection and monitoring. Therefore a voltage divider between

the input voltage and the VIN pin is required. The recommended resistor values for different input voltage ranges

can be found in Table 5.2. For different nominal input voltages, the respective component values with the maxi-

mum supported input voltage are listed. Optionally, a capacitor, typically 10nF, can be connected to the VIN pin to

help improve accuracy.
