Can anyone help me design a load switch using the Infeneon IPP120P04P4L p channel MOSFET and the necessary filter components? I would like to use the Texas Instruments ULN2803A darlington driver to drive the MOSFETs gate. Helpful details; Automotive application supplying fuel pump, injector and other hardware. Expected voltage 11 to 16. Electrical noise from alternator. Voltage and current spikes. I would prefer to run switch without heatsink. Thanks.
Edit: I would like design advice and review of this circuit redone directly from Infineon BTF5060-1TEA smart high side power switch data sheet. Has anyone ever used this device before? I intend to use a raspberry Pi 3 to command the appropriate PWM duty cycle to a fuel pump to assist in adjusting fuel pressure through this Smart switch. Fuel pump max current draw will be around 20 Amps. What frequency would you use? Any additional components you would add? Thanks
This is the diagram of the system I’m using TXS0108EPWRG4 level converter but in this case I’m using them as buffers to protect raspberry pi. To monitor current draw and voltage I’m using INA260 power monitors.
