DS1830AS+

Supervisors Overview

The DS1830AS+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed as a voltage sequencer with manual reset capabilities. It features two monitored inputs and operates within a supply voltage range of up to 5.5 V. The device provides an active low, open-drain output type and includes a reset delay time of 75 ms. It detects power failures and has a threshold voltage of 3.3 V with an accuracy of 20%. The component functions without a watchdog timer or battery backup switch. It supports a maximum operating temperature of +85 C and a minimum of -40 C, drawing a working supply current of 25 uA.
