Typical Application Circuit

The picture here shows a typical application circuit and the components required around the BD39040MUF-C for operation. A small capacitor is needed on the VDD line to remove any high frequency noise. All the inputs are tied to the voltage rails that are being monitored through the voltage divider resistor network. The resistor values can be selected based on the voltage level that needs to be monitored. A pull-up resistor is needed at each of the outputs to signal the processor when the voltage level is within the limit. A resistor on the RTW pin can select the WDT time setting. Detailed information on this can be found on the BD39040MUF-C datasheet.
