I am connecting the input with output by XT150 Connector, But there are some spark is coming while connection, Because load is ESC with BLDC motor.So it will draw approx 5-10 Amp current while connectingh the battery source. I am planing to put a el...
Increase the gate-driver current, possibly lowering switching losses. The MOSFETs own internal gate resistance, which ultimately limits the gate-driver current, places a practical limit on this approach. Use an improved MOSFET technology that might simultaneously switch faster, have lower RDS(ON), ...
