The XC6122C340MR-G is part of the XC6122 series of Voltage Supervisors by Panasonic. This integrated circuit is a supervisor, which monitors power supply system voltage, detects and protects against under-voltage and over-voltage conditions. It is based on the integration of a voltage comparator, an over-voltage comparator, a low supply voltage detector, reset circuitry and a manual reset input.The XC6122C340MR-G is an integrated PMIC (Power Management IC) supervisor specifically designed to provide high accuracy voltage monitoring and power supply protection. It is suitable for use in circuits operating on wide operating supply voltages ranging from 1.5V to 5.5V.The XC6122C340MR-G is based on a Voltage Comparator. It is designed to operate on +3.3VV and +5V power supplies and requires a minimum supply current of 3.5mA. The Voltage Comparator uses two reference voltages to enable voltage comparison and comparison of output voltage levels via internal switching. When the battery voltage is lower than the reference voltage, the device will detect an under-voltage and produce a Reset indication up to 1.2V.In terms of its working principle, the XC6122C340MR-G integrates reset circuitry, which will determine the reset flag that is then sent to the system. The reset flag can be triggered by a fault flag provided by the system itself, or an external reset override of a manual reset flag generated by pressing the reset button of the device. When the under-voltage or over-voltage conditions are removed, the reset flag is removed and the supply voltage returns to its nominal value, the latch reset flag is cleared. The XC6122C340MR-G application field includes but is not limited to consumer electronics, automotive and industrial applications. This particular device can operate as a power supply supervisor, power-on reset (POR) circuit, brown-out detector (BOD) circuit, and fault latch for over-voltage, and over-current events. It can also work in conjunction with a push-pull transistor and an output buffer so that an output signal is triggered for an established period of time in response to an input signal. Specifically, it can be used in application such as LCD (liquid crystal display) and LED (electrical discharge) backlighting, inverters, and other low voltage, low current applications.The XC6122C340MR-G is also extremely versatile and comes with two power saving modes, active mode and standby mode. The standby mode is used to further reduce the overall power consumption of the device. It can therefore be used in a wide variety of applications that require minimal power consumption but must remain reliable.In conclusion, the XC6122C340MR-G is an excellent choice for power supply protection and voltage monitoring. It is suitable for application ranging from consumer electronics and automotive to industrial, and it is versatile enough to handle all types of power saving, low voltage and low current applications. The fully integrated package combined with its low power consumption makes it an extremely cost effective and reliable solution.
