Introduction

The DS1831AS+ is a voltage supervisor from the PMIC (power management integrated circuit) – Supervisors family. It is a cost effective, small footprint active-low reset IC (integrated circuit) for providing power-on reset functionality for battery-operated and 3.3V or 5V applications.

Applications

The DS1831AS+ is a low-cost active-low reset IC with a wide array of applications. It is designed to be used in automotive, industrial, communications, and consumer markets. The device is designed with an adjustable supply voltage (3.3 - 5.5V) with protection against over-voltage and under-voltage conditions, making it ideal for applications with fluctuating power needs. In addition, the DS1831AS+ also serves as a power-on reset signal to the microprocessor or microcontroller once the supply voltage declines below the reset threshold.

Features

The DS1831AS+ contains a voltage-controlled reset output, an active-low reset signal, and a power-on reset timer (80qS - 20ms adjustable). The timer will produce a reset signal once the supply voltage drops and stays below the reset threshold for the selected time period. This state-of-the-art voltage supervisor provides higher accuracy and better stability than most competitive products.

Functional Description

The DS1831AS+ consists of a voltage monitor, delay timer, and a reset output. The monitor consists of a voltage-controlled oscillator with hysteresis to detect different power supply states. When the supply voltage drops, the oscillator triggers and the delay timer starts to count. After the timer counts down to zero, the reset output signal is active. The reset signal remains active until the supply voltage increases above the reset threshold.

Conclusion

The DS1831AS+ is an ideal active-low reset IC for battery-operated and 3.3V or 5V applications. Its wide array of features like its adjustable supply voltage, protection against over-voltage and under-voltage conditions, and its power-on reset timer make it ideal for a number of uses. The DS1831AS+ is an outstanding voltage supervisor from the PMIC – Supervisors family and promise to meet the needs of many different applications.
