This datasheet provides STM1810, STM1811, STM1812, STM1813 STM1815, STM1816, STM1817, STM1818 features description, including precision monitoring of 3V, 3.3V, and 5V supply voltages, four output configurations, reset pulse width, low supply current, guaranteed assertion down to VCC = 1.0V, factory-trimmed reset thresholds, power supply transient immunity, push-button/manual reset detect, operating temperature, ±2.5% reset threshold accuracy and SOT23-3 package.
This document provides preliminary information on the STM1810, STM1811, STM1812, STM1813, STM1815, STM1816, STM1817, and STM1818 Low Power Reset Circuits. These devices are designed to monitor power supplies for microcontrollers, asserting a reset signal when the supply voltage drops below a preset value and maintaining it for a minimum period of time.
