Maxim Integrated MAX706AREPA+ Microprocessor Supervisory Circuits
The MAX706AREPA+ from Maxim Integrated is a highly reliable and efficient microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with +5V-powered circuits.
This supervisory circuit ensures that the µP is fully reset during power-up, power-down, and brown-out conditions. The MAX706AREPA+ features a combination of functions such as reset output during power-up, power-down, and brown-out conditions, manual reset capability, and watchdog timer. The reset output is guaranteed to remain in the active state for a minimum of 100ms after VCC has risen above the reset voltage threshold, providing ample time for the system to stabilize.
Key Features:
- Precision monitoring of +5V power-supply voltages
- Fully specified over temperature
- Reset threshold voltage: 4.65V
- 200ms reset pulse width
- Watchdog timer with 1.6s timeout (min)
- Manual reset input
- Debounced TTL/CMOS-compatible manual-reset input
- Active-low RESET output
The device is packaged in an 8-pin PDIP (Plastic Dual In-line Package), which is suitable for through-hole mounting, making it easy to integrate into a variety of system designs. The MAX706AREPA+ operates over the extended industrial temperature range of -40°C to +85°C, ensuring reliable performance in diverse operating environments.
With its combination of features, the MAX706AREPA+ is ideal for use in applications such as computers, controllers, intelligent instruments, critical µP and µC power monitoring. It is designed to enhance system reliability and reduce the complexity of designing power management functions in digital devices and embedded systems.
By choosing the MAX706AREPA+ supervisory circuit, designers can trust in Maxim Integrated's reputation for quality and performance, ensuring that their systems maintain optimal functionality and stability.
