Overview
FEATURES Specified over temperature Low power consumption: 17 μA Precision voltage monitor: 3 V, 5 V options Reset assertion down to 1 V VCC 30 ms minimum power-on reset Logic low RESET output Available in SOT-23 and SC70 packages APPLICATIONS Microprocessor systems Computers Controllers Intelligent instruments Automotive systems GENERAL DESCRIPTION The supervisory circuit of the ADM809-5L/ADM809-5S monitors the power supply voltage in microprocessor systems.
It provides a reset output during power-up, power-down, and brownout conditions.
On power-up, an internal timer holds reset asserted for 55 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 ADM809-5L/ADM809-5S provide an active low reset signal (RESET).
The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC.
The ADM809-5L/ADM809-5S consume only 17 μA, making them suitable for low power, ...
