PMIC - SupervisorsThe XC6124D740MR-G is a microprocessor (MPU) supervisor. MPU supervisors are used to monitor and protect microprocessors from unexpected power drops and from accidental resets due to low voltage levels. This particular supervisor was developed by ROHM Semiconductor for use in automotive applications.The XC6124D740MR-G is a 2-channel monitoring device, which makes it ideal for monitoring both primary power supply and backup power supply. It offers an adjustable voltage monitor that monitors the voltage of the power supply, and it also includes a power-on-reset (POR) output that is activated when the power supply\'s voltage drops below a certain threshold.The XC6124D740MR-G also features a power-on reset (POR) channel to reset the processor and all its peripheral devices when the power supply drops below a predetermined level. This ensures that the processor and its peripherals are restarted at a known safe state. It also features a watchdog timer that is activated if the processor does not periodically reset itself. This feature is designed to ensure that if the processor encounters a fault or a problem, the processor will automatically be reset and the problem resolved.The XC6124D740MR-G is designed with a wide range of input voltage capabilities. It can be used with a variety of power supplies, such as 1.8V to 5.5V or an adjustable voltage range, to suit different applications. The device also includes voltage supervisor hysteresis to avoid unnecessary reset cycles.The XC6124D740MR-G also includes an undershoot and overshoot protection function to protect the processor against extreme push-pull transitions. This feature provides protection against transients caused by switching noise, power supply deglitching and overvoltage conditions.In addition, the XC6124D740MR-G features a reset signal output signal that is active when the supervisor detects a reset signal. This signal can be used to reset peripheral components when the supervisor detects a fault condition. The signal is generated when the voltage of the power supply drops below the threshold voltage of the power-on reset (POR) channel.The XC6124D740MR-G also has a wide operating temperature range of -40 to +125 degrees Celsius. This is ideal for automotive applications where operating temperature range is more challenging.In conclusion, the XC6124D740MR-G is an ideal microprocessor supervisor for automotive applications due to its wide input voltage range, voltage supervisor hysteresis, reset signal output, undershoot and overshoot protection, and wide thermal range. It is an ideal solution for applications requiring reliable and automatic reset and monitoring of microprocessors.
