MC100E137FNG is a low voltage detector that can be used as a reset interface in numerous devices. This circuit has a detecting voltage range between 3.8V and 5.5V, setting the reference voltage to 4.2V. It has a fast recovery time and minimal power consumption, making it a popular choice for use in reset applications.

The MC100E137FNG has two key components – the logic input stage and the output buffer. The logic input stage of the circuit includes a voltage divider, a comparator, and a CMOS logic inverter. The voltage divider is used to take the incoming voltage and divide it by a preset ratio in order to give the comparator a reference level. The comparator then compares the divided voltage with the reference level and produces an output depending on whether or not the input voltage is greater than the reference voltage. The output of the comparator is then sent to the CMOS logic inverter, which inverts the signal before it is sent to the output buffer. The output buffer then takes the signal from the inverter and produces the reset signal.

The MC100E137FNG is mainly used to detect voltage levels in order to enable or disable different devices or systems. For example, it can be used in an automotive environment for resetting the airbag system when the system is disabled due to a particular type of electrical failure. It can also be used in medical applications for resetting the emergency call systems when the battery level drops below a certain threshold. Moreover, it can be used in television sets to reset when there is a power surge due to poor electrical connections.

The working principle of the MC100E137FNG reset interface is quite simple. As described above, the incoming voltage is divided by a preset ratio and the output of the comparator is then sent to the CMOS logic inverter. The inverter then inverts the signal, sending it to the output buffer, which then outputs the reset signal. This reset signal can then be used to enable or disable different systems or devices.

Overall, the MC100E137FNG is a popular low voltage detector with a fast recovery time and minimal power consumption. It is mainly used for detecting voltage levels and resetting various systems and devices in the event of power surges or electrical failures. The working principle of the circuit is quite simple, with the incoming voltage being divided and compared with the reference voltage, before being sent to the input stage logic and eventually to the output buffer.
