Abstract
A system may include a power source. The power source supplies a first voltage. The system may also include a voltage regulator that receives the first voltage and supply a second voltage. Additionally, the system may include a microcontroller that receives the second voltage and output the second voltage via an output pin. Further, the system may include a switching element that receives the second voltage from the output pin of the controller at a first terminal and receives the first voltage from the power supply at a second terminal. The switching element selectively charges a first capacitor based on a difference between the first voltage and the second voltage.
