MOSFET gate driver circuit

Published:2011/7/19 8:47:00 Author:Fiona | Keyword: MOSFET gate, driver | From:SeekIC

MOSFET driver circuit adds a regulator VD1 (UDRM = 8.3V) in the gate and gives the regulator a constant driving voltage,it can ensure MOOSFET always have a very good conduction. MOSEFT machine drive current is controlled by the Rg1 and Rg2,they can reduce the noise through controlling the MOSFET switching speed.When the MOSFET is off, the gate can be discharged through the resistor Rg1 to make the MOSFET quickly close and get the minimum switching loss,it is shown as above.
