MIC2775-46YM5 Supervisor Push-Pull, Totem Pole 1 Channel
The MIC2775-46YM5 is a high-precision complementary output microprocessor supervisory reset IC from Microchip Technology (formerly Micrel), housed in an ultra-compact 5-pin SOT-23 surface-mount package. It features 4.68V precision reset threshold, 140ms minimum guaranteed power-on reset timeout, both active-high and active-low complementary reset outputs, and 1µA ultra-low quiescent current, specified for -40°C to +85°C industrial temperature range, making it a highly reliable, space-saving 5V system power monitoring and dual-reset solution for industrial control systems, automotive non-safety auxiliary modules, and high-performance 5V embedded platforms.
Key Features and Highlights
1. 4.68V Precision 5V System Reset Threshold: Accurate 4.68V reset detection threshold perfectly matches standard 5V digital system power supply requirements, triggering reliable reset before system voltage drops below 5V MCU and logic IC stable operating voltage to prevent abnormal code execution.
2. Dual Complementary Active-High/Active-Low Reset Outputs: Native complementary dual-output structure provides both active-high and active-low reset signals simultaneously, directly driving mixed-signal systems that require both reset polarities without extra discrete logic components.
3. 140ms Minimum Guaranteed Power-On Reset Timeout: Fixed 140ms minimum reset delay ensures system power rail fully stabilizes before releasing reset, eliminating unstable system startup issues caused by insufficient power supply rise time and transient voltage dips.
4. 1µA Ultra-Low Quiescent Current: Extremely low operating supply current minimizes extra system power overhead, drastically extending battery runtime for low-power 5V battery-powered portable industrial devices and field-deployed sensor nodes.
