AS1918 - Microprocessor Supervisory Circuit

This page provides the datasheet information for the AS1918, a member of the AS1916 Microprocessor Supervisory Circuit family.

Description

The AS1916 - AS1918 microprocessor supervisory circuits were designed to generate a reset when the monitored supply voltage falls below a factory-trimmed threshold.

The reset remains asserted for a minimum timeout period after the supply voltage stabilizes.

Features

VCC Supervisory Range: +1.8 to +3.6V Guaranteed Reset Valid Down to VCC = +1.0V Reset Timeout Delay: 215ms Manual Reset Input Three Reset Output Types - Active-Low Push/Pull (AS1916) - Active-High Push/Pull (AS1917) - Active-Low Open-Drain (AS1918) Watchdog Timeout Period: 1.5s Immune to Fast Negative VCC Transients External Components Not Required Operating Temperature Range: -40 to +125°C 5-pin SOT23 Package 3.

Technical coantmesntAsGtill valid Datasheet AS1916 - AS1918 Microprocessor Supervisory Circuits with Manual Reset and Watchdog 1 General Description The AS1916 - AS1918 microprocessor supervisory circuits were designed to generate a reset when the monitored supply voltage falls below a factory-trimmed threshold. The reset remains asserted for a minimum timeout period after the supply voltage stabilizes. Guaranteed to be in the correct state for VCC higher than +1.0V, these devices are ideal for portable and battery-powered systems with strict monitoring requirements. The devices feature factory-trimmed thresholds to monitor a supply voltage between 1.8 and 3.6V. The devices are available with the reset output types listed in Table 1. Table 1.
