S-80122BLMC-JEHT2U

The S-80122BLMC-JEHT2U is a supervisor integrated circuit (IC) that is primarily used to provide an accurate and reliable monitoring of a host circuit’s operating parameters. By employing two comparators, this device measures the supply voltage and sends out an alarm when the voltage stays out of a designed range.

Application Fields

The S-80122BLMC-JEHT2U is principally helpful in the areas of system and power monitoring. Serve in the role of power supply voltage monitors, they are intended to be attached to the circuit which is being monitored. When the input supply falls below the pre-determined value, a push-pull output provides both a reset and an alarm signal.

Working Principle

The S-80122BLMC-JEHT2U employs two voltage comparators to monitor two supply voltage levels. The total number of pins is 5 and these are the power supply pin, reset pin, comparator pin, and two output pins. When the voltage increases, the supply voltage pin provides voltages to the comparator and to the reset pin. The reset pin is used to set the two supply voltage thresholds.

The comparator pin of the S-80122BLMC-JEHT2U compares the voltage at the supply voltage pin and the reset pin when a high input voltage is applied. Upon comparing the voltage, the output terminals connected to the output pins carry out the predefined output function such as a reset or an alarm. The output voltage level of the S-80122BLMC-JEHT2U is set to 3.3 V or it can be adjusted.

Conclusion

The S-80122BLMC-JEHT2U is a supervisor IC that can provide accurate and reliable monitoring of a host circuit’s operating parameters. It is ideal for use in power supplies, medical instruments, and various other electronic circuits where voltage surge, overshooting, or under-voltage must be detected. With its two power supply voltage thresholds and its four output pins, the S-80122BLMC-JEHT2U is an attractive and cost-effective choice for voltage monitoring.
