MAX690ACPA Description

Short technical summary and product information.

The MAX690ACPA from Maxim Integrated is a versatile microprocessor supervisory circuit that simplifies power supply monitoring and battery control in μP systems. It provides critical functions such as a reset output during power fluctuations, battery-backup switching for CMOS RAM or microprocessors, and a watchdog timer to ensure system reliability.

 

Key electrical specifications include a precision supply voltage monitor with a threshold of 4.65V for the MAX690A series, a reset time delay of 200ms, and a watchdog timer with a 1.6s timeout. The device also features low quiescent supply currents of 200μA and 50nA in battery-backup mode.

 

This supervisory IC is available in 8-pin DIP and SO packages, supporting through-hole mounting. Its applications include battery-powered computers, intelligent instruments, and critical μP power monitoring, where reliable power management is essential.

 

The MAX690ACPA enhances system reliability and accuracy compared to discrete component solutions, making it an ideal choice for robust power monitoring in embedded systems.
