Product Summary

The ADM809MARTZ-REEL7 supervisory circuit monitors the power supply voltage in microprocessor systems. The device provides 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 ADM809RAKSZ-REEL7 provides an active low reset signal (RESET). The device has push-pull outputs. The ADM809MARTZ-REEL7 is ideal for: (1)Microprocessor systems; (2)Computers; (3)Controllers; (4)Intelligent instruments; (5)Automotive systems.
