IC LM293
New Integrated circuitsA well-known dual differential comparator that operates over a supply voltage range of 2V-36V. The output is compatible with TTL (transistor-transistor logic), CMOS (complementary metal-oxide-semiconductor) and MOS. Some of its uses are peak detection, supply voltage monitoring and correction, oscillator circuits, and general industrial use. You can find it in many inverter welding machines. Package - SO-8
