The 20 ms minimum reset timeout holds the processor in reset long enough for the supply to stabilise after a brownout event — a common requirement for microcontrollers that need a clean power-on reset sequence. ## Package and temperature grade for the bill Housed in a SOT-143 package (TO-253-4, TO-253AA), the device occupies a compact footprint on the PCB.","metaTitle":"MIC6315-46D2UY Power Supply Monitor, 4.63V Threshold","metaDescription":"Microchip MIC6315-46D2UY power supply monitor, active-low open-drain reset, 4.63V threshold, 20ms min timeout, -40°C to +85°C, SOT-143.
