MAX690ACSA+T Description

Short technical summary and product information.

The MAX690ACSA+T is a microprocessor supervisory circuit designed by Analog Devices / Maxim Integrated. This component is crucial for monitoring power supply conditions in microprocessor systems, significantly improving system reliability and accuracy. It provides a reset output during power-up, power-down, and brownout conditions, ensuring stable operation.

 

Key electrical features include a precision supply voltage monitor with a threshold of 4.65V and a reset timeout of 140ms minimum. It also incorporates a watchdog timer with a 1.6s timeout and battery-backup power switching capabilities. The device operates with a quiescent supply current of 200µA, reducing power consumption, and a low 50nA in battery-backup mode.

 

Packaged in an 8-SOIC format, the MAX690ACSA+T is designed for surface mount applications. Its operating temperature range is 0°C to 70°C (TA). This supervisory circuit is suitable for critical μP power monitoring in battery-powered computers and controllers, as well as intelligent instruments.

 

The device guarantees reset assertion down to 1V VCC. It offers a push-pull, totem pole output and monitors a single voltage. The MAX690ACSA+T is RoHS3 compliant, has an MSL of 1, and is REACH unaffected, though these compliance statuses are currently unverified.
