Description

The STM811SW16F is a microprocessor Reset Circuit with active-low push-pull output and pushbutton reset input (MR). The low-power supervisory device used to monitor power supplies. It performs a single function - asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time (trec).
Guaranteed /RST assertion down to VCC = 1V
140ms Minimum reset pulse width
6µA Typical low supply current
