The 140ms minimum power-on reset timeout ensures reliable processor initialization, while RESET is guaranteed valid for VCC down to 1V. Drawing only 12uA, the device requires no external components and fits in a tiny 3-pin SOT-23 package.","working_principle":"The MAX809 continuously compares VCC against an internal 2.93V reference threshold. When VCC drops below the threshold, RESET is asserted low. After VCC rises above the threshold, the internal timer maintains RESET low for at least 140ms to allow the power supply and processor to stabilize. The push-pull output stage provides strong drive without an external pullup resistor. Power supply transient immunity prevents false resets during brief voltage dips.","pin_description":"
