Ultra-Small High-Side N-Channel MOSFET Driver - Microchip …

WebAn on-chip charge pump is switched in when needed to turn on the top N-channel MOSFET continuously. Special circuitry ensures that the top side gate drive is safely maintained in the transition between PWM and DC opera-tion. The gate-to-source voltages are internally limited to 14.5V when operating at higher supply voltages. WebA charge pump gate drive (CPG) that can reduce the turn-on loss is presented in this article. By precharging the charge-storage capacitor in the gate drive with a charge pump circuit, the gate drive output voltage is pumped up to provide higher gate current during the turn-on transient. As a result, the turn-on time and loss is decreased.
