What are the functions and functions of the lm393 chip?
LM393 Introduction:
LM393 is a dual voltage comparator integrated circuit.
The output load resistor can be connected to any power supply voltage within the allowable power supply voltage range, and is not limited by the Vcc terminal voltage value. This output can be used as a simple SPS open circuit to ground (when no load resistor is used) being used), the sink current in the output section is limited by the available drive and the beta value of the device. When the limit current (16mA) is reached, the output transistor will exit and the output voltage will quickly rise.

Main functions
LM393 package shape
The output load resistor can be connected at On any supply voltage within the allowable supply voltage range, it is not limited by the voltage value of the Vcc terminal. The sink current of the output part is limited by the possible drive and the β value of the device. When the limit current (16mA) is reached, the output transistor will exit and the output voltage will rise quickly. The output saturation voltage is limited by the γSAT of the output transistor of approximately 60ohm. When the load current is small, the output transistor's low offset voltage (approximately 1.0mV) allows the output to be clamped to zero level.
