ADM810SARTZ 监控电路IC

ADM810SARTZ

监控电路 RESET GENERATOR I.C.

Microprocessor Supervisory Circuits  in 3-Lead SC70 and SOT-23

GENERAL DESCRIPTION ADM810SARTZ

The 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.
