The MAX690SCSA+ is a microprocessor supervisory circuit from Analog Devices, designed to reduce component count and improve reliability in µP systems. It is suitable for systems powered by 3.0V or 3.3V supplies.
Key features include a precision supply-voltage monitor with a threshold of 2.925V, an active-low reset output with a 140ms minimum timeout, and a watchdog timer with a 1.6-second timeout. The device also supports battery-backup power switching and guarantees RESET assertion down to 1V.
This supervisory circuit is ideal for critical µP power monitoring applications, battery-powered computers, embedded controllers, intelligent instruments, and portable equipment. It comes in an 8-pin SOIC package suitable for surface mounting.
The MAX690SCSA+ operates within a temperature range of 0°C to 70°C (TA). Its low supply current (40µA typical for VCC and 1µA for battery) makes it suitable for power-sensitive applications.
