Drive enhancement in switch driver circuitry

摘要

A driver circuitry includes a capacitor, a first switch, and a second switch. The capacitor includes a first node and a second node. The first switch is electrically coupled to the first node of the capacitor. The second switch is electrically coupled to the second node of the capacitor. Additionally, the second node of the capacitor and the second switch are electrically coupled to an output pin of the driver circuitry operable to drive an external switch. As discussed herein, settings of the first switch and the second switch control a voltage outputted from the output pin and charging of the capacitor.
