in my gas cooking electronic project we first used AUIPS7221 for gas solenoid valves, but we had systematic breakage problems with the sparks caused to ignite the gas. a lot of testing was done and we decided to use the BTS4175SGA instead.
the component is powered at 48V stable and has esd protection.
The problem was ruptures caused by overvoltages induced by sparks caused externally by ignition of kitchen gas.
we have thought, however, to protect both the inputs and the power supply during this process with beads and capacitors as well as with capacitors since the pulses are of the order of 200nsec and with tvs.
do you think this solves the problem?
