Most μP supervisor ICs has reset threshold voltages between 5% and 10% below thevalue of nominal sup-ply voltages. This ensures a reset will not occur within 5% of then om inal supply, but will occur when the supply is 10% below nominal. When using IC srated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply isbetween 5% and 10% low, and where the reset may or may not be asserted

最μP主管ICS的复位阈值电压5%和10%低于标称供应电压值之间。这确保了复位不会发生在5%的OM最终供应，但何时会出现供应低于10%的名义。采用IC额定只有标称电源±5%时，这使得不确定性的供应在5%和10%低区，并在复位可能会或可能不会声称
