MOSFET Gate Driver TTL-CMOS

00:25:04

General MOSFET need gate driver to use another voltage system as TTL, CMOS, etc...

This circuit can drive medium power & low voltage MOSFET like as IRFZ44N, NCE80H11...

Features : 
Signal level converting
Low impedance Gate signal power
Gate-Source overvoltage protection (±12.3V)

Need differential voltage between Driver VCC and MOSFET Drain point ＞ Vgs(th.ON)

Max drive MOSFET Gate charge ＜ 300nC
Max drive Frequency ＜ 100KHz

Drive voltage range : 3.3 ~ 12V

Minimum part requirements : 
NPN TR : 2SC1815
PNP TR : 2SA1015
Diode : 1N5819
Zener : 1N4742

(22nF capacitor is test Gate capacitance)
