AN-1033 Load power monitor using greenpak2
In this application the GreenPAK2 monitors the power on a load within the range (0.5W - 1.5W) by measuring the voltage and the current on the load. Two of the outputs drive indicator LED’s to show the status. In this design example, the voltage range to be monitored is between 3.5V - 5.5V. PIN4 is configured as Analog in, which takes its value from the output of the voltage divider Vx. ACMP0 & ACMP1 compare the value of the input against the desired limits derived from the voltage divider ratio.
