The AWS70803 supervisory circuit monitor the power supply voltage in microprocessor and digital systems. It provides a reset output during power-up, power-down and brownout conditions. On power-up, an internal timer holds reset asserted for 200ms. This holds the microprocessor in a reset state until conditions have stabilized. The RESETN output remain operational with VCC as low as 1V. The AWS70803 provides an active low reset signal (RESETN). The AWS70803 has open-drain output.
Eight reset threshold voltage options are available, suitable for monitoring 1.8V, 2.5V, 3.3V, and 5V supply voltage.
The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC.
The low supply current of typically 1.6μA makes the AWS70803 ideal for using in portable, battery operated equipment. It is specified over the extended -40°C to +125°C temperature range.
