Make money with z44 datasheet

z44 datasheet


When you run a DC motor on the H-Bridge, you are not drawing a lot of current all the time, only when the motor is accelerating or decelerating , so the Mosfet's have time to cool in between. In order to reduce overheating with constant high loads such as a light bulb, you will need to drive the lower mosfet's with more than 12V - hence you need to modify the original circuit. You guys could test this manually, but be very careful not to cause shoot through: Connect 0V Ground to one of the upper mosfet GATE, connect 12V to the OPPOSITE lower mosfet GATE.
