PMIC supervisors are devices that monitor a system\'s power supply and reset the voltage when needed. The X4163P-4.5A is a PMIC supervisor designed for use with microcontrollers, processors and DC-DC converters. It ensures constant availability of the microcontroller or processor by resetting the power supply when needed. It also protects against over-voltage and over-temperature conditions, as well as low supply voltage. This application note provides an overview of the X4163P-4.5A\'s application field and working principle.

Application Field

The X4163P-4.5A\'s application field includes microcontroller and processor-based systems, such as those used in industrial and automotive applications, consumer electronic products and communication equipment. It is a low-cost, low-power solution that can be used in a variety of applications, such as power supply monitoring, power management, voltage and current regulation, power sequencing and system reset functionality. It is also well suited for use in distributed systems, where power is provided by a distributed network of power supplies.

Working Principle

The X4163P-4.5A operates according to an internal time sequence, which monitors the manufacturer-specified limit for its nominal VDD voltage level. The device takes an error-corrected voltage measurement of the power supply at regular intervals. If the voltage falls below the limit for its nominal VDD voltage level, the device asserts an active-low reset signal, which will reset the system. The reset is also asserted if the device detects a sudden increase or decrease in the power supply voltage, or if the voltage goes above or below its upper and lower supply voltage limits.

The X4163P-4.5A\'s voltage monitor feature activates the reset signal when the output voltage is outside the specified limits. The device can also be programmed to detect a gradual change in the power supply voltage, and can be programmed to capture and hold an event counter for the number of times a reset occurs. The device can be programmed to detect low voltage at the beginning of power-up, or during operation, and can also sense an over-voltage condition.

The device also features an adjustable temperature monitor, which will activate the reset signal when it detects an over-temperature situation. In addition, the device can be programmed to monitor and compare the two channels of its digital high-side and low-side current sensor. The device will issue a reset if the current in either channel exceeds the user-defined threshold.

The X4163P-4.5A is a small-footprint, low-power PMIC supervisor that can be used in a wide variety of applications. Its small size, low power requirements and easy programming make it an ideal choice for power supply monitoring and reset functionality in microcontroller and processor-based systems.
