MIC1810_U中文资料麦瑞半导体数据手册PDF规格书

Description

The MIC1810 is an inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor based systems.

The function of these devices is to assert a reset if the power supply drops below a designated reset threshold level. Several different reset threshold levels are available to accomodate 5, 10, or 15 drop in 5V powered systems.

The MIC1810 has an active low RESET output. The reset output is guaranteed to remain asserted for a minimum of 100ms after VCC has risen above the designated reset threshold level. The MIC1810 comes in a 3-pin SOT-23 package.
