M5174P - FLAME DETECTOR
Monolithic integrated circuit M5174P is designed for the use of the flame detection circuil.
It is composed of current amplifiers, a thyristor circuit, a couple of the relay drivers and a internal voltage regulator.
The current limiting circuit of the driver and internal two sets of shunt circuits p
