PMIC - SupervisorsThe APX810-44SAG-7 is a power management integrated circuit (PMIC) supervisor that is designed specifically to help protect digital circuits from overvoltage and turn-on transients. It is part of a family of APX devices that gather a variety of different features to help manage and protect power consumption in a wide variety of applications.The APX810-44SAG-7 is capable of supplying thresholds from 0.335V to 6.225V with a tolerance of ±0.2%. It combines precision voltage references, a watchdog timer, two general purpose inputs, and a temperature monitor for comprehensive power control. The device also has a built-in push-pull output to help with the selectable power on reset functionality. It is designed for use in highly integrated systems that require low power consumption, fast start-up times, and precision voltage thresholds.The main purpose of the APX810-44SAG-7 is to monitor system input voltages and provide a power on reset signal when a specific threshold is reached. The device is able to detect over voltage and under voltage conditions, as well as low-level, high-level, and temperature threshold conditions. If these conditions are detected, the device will deliver a reset signal to the system. This reset signal can help protect the system from potential damage due to high system voltages or temperature spikes, as well as provide a non-maskable reset when the conditions occur, ensuring that the system is able to quickly reset itself.The voltage and temperature thresholds of the device can be set via the built-in digital trimming option. This option allows the user to customize the device for a wide range of input voltage and temperature conditions. Additionally, this trimming capability also allows the user to control how quickly the device responds to an over-voltage or under-voltage situation. The device has a relatively quick response time ranging from 0.2ms to 8ms (depending on trimming setting).The device also has two general purpose inputs that allow the user to give external control to the device. The inputs can be used for a variety of purposes, such as providing the means for the user to reset the system, setting system parameters, and specifying current limits. The general purpose inputs can also be used to determine if a critical temperature threshold has been exceeded.The APX810-44SAG-7 is also equipped with a watchdog timer that can be used to detect erroneous conditions within the system. If the timer is not reset within a specified period of time, the device will reset the system and deliver a reset signal. This reset signal can be used to detect a range of conditions, such as system lockups, incorrect data readings, and erroneous code execution.In summary, the APX810-44SAG-7 is a powerful PMIC supervisor that combines precision voltage references, a watchdog timer, two general purpose inputs, and a temperature monitor for comprehensive power control. It is designed for use in highly integrated systems that require low power consumption, fast start-up times, and precise absolute temperature thresholds. The device has a built-in push-pull output for selectable power on reset functionality, as well as a digital trimming option for adjusting over-voltage and under-voltage thresholds and response times. The device also has two general purpose inputs for external control, as well as a watchdog timer for detecting erroneous conditions. With its robust feature set, the APX810-44SAG-7 is an ideal solution for a variety of power management applications.
