The ADM690AARN is a single-chip solution for power supply monitoring and battery control in microprocessor systems, offered by Analog Devices. This supervisory circuit includes features such as a precise 4.65V supply voltage monitor and a reset timeout of 140ms minimum. It ensures reliable operation by asserting a reset signal during power-up, power-down, and brownout conditions, with the reset output remaining operational down to 1V VCC.
The device also incorporates automatic battery backup power switching for low-power devices like CMOS RAM or microprocessors. A watchdog timer with a typical timeout of 1.6 seconds provides an additional layer of system reliability by generating a reset pulse if the monitored system fails to toggle the watchdog input within the specified time. The ADM690AARN has a quiescent supply current of 100 mA.
Designed for ease of integration, the ADM690AARN is available in a space-saving 8-SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA), making it suitable for a variety of environmental conditions. This component is ideal for applications requiring robust power monitoring and system supervision.
