I have a rather simple circuit that acts as an overvoltage protection switch with an input control signal to enable/disable the output.On the final output I am driving a motor that consumes around 2A in the startup phase for 200-300ms and around 500mA constant. My input voltage is in the region of 12-30V
The issue is that I have a very large voltage drop across the transistor when the motor starts to spin up, but according to the datasheet this transistor should be able to handle large current. main pnp datasheet
Does anybody know why the drop across my FZT956 PNP transistor is so high? I need to reduce it because the motor is used in a pulsed fashion so I need to minimise the heating in this period.
