Introduction to APX803L-29SA-7

APX803L-29SA-7 is a power supervisor IC (PMIC) from ON Semiconductor designed to protect circuits from components failing due to over-voltage, under-voltage, brown-out, over-temperature, and overcurrent conditions. This IC monitors voltage, temperature, and current conditions of the system and provides fail-safe protection for the circuit by allowing for power-down or power-off activation of the system if any of the monitored conditions are in violation. It has a wide input voltage range of 1.8V to 5.5V, an adjustable input current limit with a maximum peak current of 770mA, and a variable maximum junction temperature protection limit.

Main Features of APX803L-29SA-7

The main features of APX803L-29SA-7 include the following:- Low Power Consumption: This IC features a low power consumption rating, making it ideal for battery-powered and low power applications.- 3-Volt to 5.5-Volt Input Range: This IC operates at an input voltage range from 3V to 5.5V, making it suitable for a variety of applications.- Over-Voltage, Under-Voltage, Brown-Out and Over-Temperature Protection: This IC provides comprehensive protection against over-voltage, under-voltage, brown-out, and over-temperature conditions.- Over-Current Protection: This IC also provides protection against over-current conditions above a threshold level.- Single Resistor Programmable Trip Points: The device features adjustable voltage and temperature trip points with a single resistor programming option.- On-Input Pin Indicator: This IC features a simple output indicator pin, which allows the user to determine the input voltage at any given time.

APX803L-29SA-7 Application Fields and Working Principle

The APX803L-29SA-7 is a highly sought-after PMIC for a range of applications including data storage, medical equipment, industrial equipment, communications and networking, and battery-powered systems. It is designed specifically to protect circuits from over-voltage, under-voltage, brown-out, over-temperature, and overcurrent conditions, keeping them functioning up to the design specification. This IC consists of a voltage regulator, a reset generator, temperature sensors, and a current limit protection circuit. The voltage regulator circuit monitors the supply voltage to ensure that it remains within the specified range, and will shut down the system when the voltage breaches the preset trip point. Similarly, the reset generator ensures that the system is reset when a fault is detected, while the temperature sensors detect any temperature conditions that are out of range. The current limit circuit detects excessive current within the system and will shut down the system when the peak current exceeds the preset limit. Overall, the APX803L-29SA-7 is an ideal PMIC for various types of equipment where protection against over-voltage, under-voltage, brown-out, over-temperature and overcurrent conditions is necessary. With its simple single-resistor programming option, as well as its comprehensive protection features, it can safeguard almost any application from unexpected power problems.
