Detailed Product Description
Product Details
GENERAL DESCRIPTIONThe ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds reset asserted for 240 ms. This holds the microprocessor in a reset state until conditions have stabilized. The reset output remains operational with VCC as low as 1 V. The ADM803 and ADM809 provide an active low reset signal (RESET), whereas the ADM810 provides an active high signal (RESET) output. The ADM809 and ADM810 have push-pull outputs, whereas the ADM803 has an open-drain output, which requires an external pull-up resistor.
FEATURESSpecified over temperatureLow power consumption: 17 μA Precision voltage monitor: 2.5 V, 3 V, 3.3 V, 5 V options Reset assertion down to 1 V VCC 140 ms minimum power-on reset Open-drain RESET output (ADM803) Push-pull RESET output (ADM809) Push-pull RESET output (ADM810) SC70 and SOT-23 packages
