Description

The ADM809SARTZ is a supervisor integrated circuit that monitors the voltage supply in microprocessor systems and provides a reset output during power up, power down, and brownout conditions. This IC is designed for applications with VCC voltage less than 5 V, which is common among modern microprocessors used in computers, controllers, and intelligent instruments.

Specifications and features

• Low 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 and ADM810)
• SC70 and SOT-23 packages

Application Scenarios

The ADM809SARTZ is commonly used in microprocessor systems, such as computers, controllers, and intelligent instruments.
