IGBT ignition coil driver

[Aeronuts]

Since the PIC is a microcontroller which gives 0 and 1 logics, I suggest to put a non-invertering hex buffer and using Logic Level IGBT. The choice of logic level IGBT so that its lesser parts count to just drive the ignition coil. Another approached I think was to use a optoisolator before feeding the logic signal to the IGBT

-- Just my opinion sir.

Try a 100R and a 5V6 zener to ground on your 5v supply to chip and hall effect.
Also a 0.01uf on the supply terminals of the hall effect right on the base of the device.
