Maxim Integrated MAX6713REXS+ Microprocessor Supervisory Circuit
The Maxim Integrated MAX6713REXS+ is a highly reliable and robust 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 systems that require voltage monitoring and processor supervision.
This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6713REXS+ has the capability to monitor voltages above +1.8V, +2.5V, +3.0V, +3.3V, and +5.0V. It is ideal for use in a variety of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.
Key features of the MAX6713REXS+ include:
- Precision Monitoring: Accurate monitoring of multiple supply voltages to ensure that the system operates reliably.
- Manual Reset Input: A manual reset input is provided to allow for a reset to be triggered with an external pushbutton or logic signal.
- Low Power Consumption: With its low power consumption, this device helps conserve battery life in portable applications.
- Reset Timeout: It features an adjustable reset timeout period which can be set by external capacitors.
- Power Supply Glitch Immunity: Ensures stable operation without false resets during power supply transients.
- Compact Package: Available in a small, 4-pin SC70 package, saving valuable board space in space-constrained applications.
The MAX6713REXS+ operates over a wide temperature range of -40°C to +125°C, making it suitable for industrial applications. Its factory-trimmed reset thresholds and built-in debounce logic provide a reliable reset signal without external components. The device's active-low reset output is guaranteed to be in the correct state for V_CC down to 1.0V, ensuring that the µP starts in a known state even during low-voltage conditions.
Overall, the Maxim Integrated MAX6713REXS+ is an essential component for systems that require dependable monitoring of their power supply and processor activity, offering a cost-effective solution for enhancing system reliability.
