摘要： An undervoltage protection circuit, system and method is prodded for sending a reset signal to an electronic device during undervoltage time periods in which the device power supply voltage is less than a desired amount. The protection circuit includes a sensing circuit and a latching network adapted to quickly discharge a storage capacitor when the sensing circuit senses the undervoltages. A buffer network is included to send a reset signal to the electronic device whenever the storage capacitor discharges to a low latched level. The reset signal exists substantially throughout the undervoltage time period and also for a set delay period after the undervoltage time period ceases. During receipt of the reset signal, the electronic device will be inhibited from incurring damage or loss of data.
