The STM1810/1811/1812/1813/1815/1816/1817/1818 is a low power reset circuit with 4 output configurations, low current, guaranteed minimum voltage, factory trimmed reset thresholds, power supply transient immunity, push-button/manual reset detection, wide operating temperature range, ±2.5% reset threshold accuracy, SOT23-3 package, and full compatibility with DS181x and MXD181x products.
The STM1810 through STM1818 are low power reset devices designed to monitor power supplies for microcontrollers. They assert a reset signal when the supply voltage drops below a preset threshold and keep it asserted until the voltage rises above the threshold for a minimum period. These devices are ideal for portable equipment and are available in the space-saving 3-pin SOT23 package.
