Web1 A peak gate driver current Built-in high side charge pump Under-voltage lockout (UVLO) Over-voltage lockout (OVLO) Global enable with <10 μA Sleep mode Supports PWM up to 100 kHz Parallel interface and input control 4 channels Load current (IL) 1 A (Typ) Drain-to-source on resistance 1000 mOhm RDS (ON) (Typ) Applications Automotive Electric Pumps 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.
WebThe 33883 is an H-bridge gate driver (also known as a full-bridge pre-driver) IC with integrated charge pump and independent high and low side gate driver channels. The gate driver channels are independently controlled by four separate input pins, thus allowing the device to be optionally configured as two independent high side gate drivers
WebThe integrated charge pump with boost circuit provides a regulated 5-V gate drive for both the high side and synchronous rectifier N-channel MOSFETs. The use of the Predictive Gate Drive™ technology and charge pump/boost circuits combine to provide a highly efficient, smaller and less expensive converter. 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.
WebOct 5, 2024 · Charge pump gate drive (CPG) A limited amount of gate current is the reason for an increased turn-on switching speed of SiC MOSFETs. To find a solution, further research concerning the factors affecting the gate current in between the process of turn-on transient with a typical VSG is needed.
