Introduction

AI Translation

MIC809 and MIC810 are low-cost microprocessor supervisory circuits designed to monitor power supplies in microprocessor-based systems. These devices assert a reset signal when the supply voltage falls below a specified reset threshold. Several reset threshold options are available to accommodate systems powered by 3V, 3.3V, or 5V supplies. The MIC809 provides an active-low /RESET output, while the MIC810 provides an active-high RESET output. After VCC rises above the specified reset threshold, the reset output is guaranteed to remain asserted for a minimum of 140ms. The MIC809/810 feature a push-pull output stage, eliminating the need for an external pull-up resistor. The MIC809/810 are available in 3-pin SOT-23 and SC-70 packages. A shorter reset timeout version (30ms minimum) is also available for the MIC809; refer to MIC809-5.
