Hello,
I have a project where i need an output which can push up to 500mA at 12V and also sink up to 500mA of current. And the circuit for this should use as minimal power as possible while nothing is connected to the output. As this is battery powered and should run as long as possible in standby.
The Output does not need to switch fast. There is now PWM or so planned for this.
The input for this circuit is a 3.3V signal from a flip flop with also has a push-pull output, but only +-20mA @ 3.3V.
Can anybody recommend a circuit/chip for this Levelshifter/Push-pull type thing which uses as little power as possible ?
In a first try is used a MCP1416 MOSFET driver, which works, but uses ~0.5mA when nothing is connected to the output. Also it looks like i have broken one when i pushed to much current into it, even with the PTC fuse in front of the MOSFET driver.
Any help is welcome
