Introduction

An ADM803RAKSZ-REEL7 PMIC - Supervisors is an integrated circuit designed to prevent a system from being permanently damaged due to system over-voltage faults, over-current faults and short circuit conditions. It is a miniature package that can be easily integrated into the system design and is used in critical circuit protection applications.

Application Areas

ADM803RAKSZ-REEL7 PMIC - Supervisors can be used in a variety of applications including automotive, consumer electronics, and industrial control systems. It is especially useful in circuits that require precise monitoring of power supply voltages and currents. Other applications of this supervisor include powering and protecting microprocessors, LED drivers, voltage regulators and battery management systems.

Features

The ADM803RAKSZ-REEL7 PMIC - Supervisors has a wide operating temperature range from -40°C to +85°C and operates over a wide input voltage range from 4.5V to 28V. Its features include an adjustable reset trip point, adjustable comparator voltage levels, adjustable shutdown delay delay period, and an over-temperature warning output. The supervisors can also be configured for open-drain or push-pull output drive configurations.

Working Principle

The ADM803RAKSZ-REEL7 PMIC - Supervisors is a programmable voltage supervisor which monitors input voltage supplied or generated in the system and provides over-voltage and under-voltage protection by generating a reset signal. It monitors the input voltage continuously, checking if it is within the set voltage range. If the input voltage is out of range, the supervisor will trip, sending a reset signal to the system circuitry, protecting the system from any damage caused by an over-voltage or under-voltage situation.The supervisors also have an adjustable comparator voltage level, adjustable reset trip point, adjustable shutdown delay period and an over-temperature warning output. The adjustable comparator voltage level feature is designed to enable the user to set the input voltage at which the supervisor will trip, and the adjustable reset trip point feature allows the user to set the voltage required for resetting the supervisor. The adjustable shutdown delay period enables the user to set the duration of reset signal when the supervisor trips, and the over-temperature warning output feature informs the user when the system temperature reaches a certain threshold.

Conclusion

In conclusion, the ADM803RAKSZ-REEL7 PMIC - Supervisors is a versatile and reliable supervisor which is designed to protect critical circuits from over-voltage faults, over-current faults and short circuit conditions. It offers adjustable reset trip points, shutdown delays and over-temperature warning outputs and is ideal for use in markets such as automotive, consumer electronics, and industrial control systems. With its wide operating temperature range and wide input voltage range makes it an ideal choice for a variety of systems.
