Maxim Integrated DS1706LEPA MicroMonitor Chip

The DS1706LEPA from Maxim Integrated is a state-of-the-art microprocessor supervisory circuit that provides a full suite of monitoring functions essential for ensuring the reliable operation of microprocessor (µP) systems. This compact and efficient component is designed to monitor power supply voltages, generate a reset signal for the µP during power-up, power-down, and brownout conditions, and offer a precise watchdog timer to maintain system integrity.

Key Features:

• Power Supply Monitoring: The DS1706LEPA actively monitors the system's power supply voltage and ensures that it remains within acceptable thresholds for stable operation. It is capable of asserting a reset signal to the µP to prevent erratic behavior in the event of power supply irregularities.
• Programmable Reset Signal: The reset output is guaranteed to remain in the active state for a minimum of 150ms after the power supply has stabilized, ensuring the µP has adequate time to initialize upon power-up.
• Watchdog Timer: A built-in watchdog timer serves as a fail-safe mechanism, requiring periodic servicing by the µP. If the µP fails to refresh the watchdog circuit within a preset time frame, the DS1706LEPA will issue a system reset, thereby preventing system hang-ups and malfunctions.
• Low Power Consumption: Designed for energy-sensitive applications, the DS1706LEPA operates with minimal power consumption, making it ideal for battery-powered and portable devices.
• Manual Reset Input: An additional feature of this MicroMonitor is the manual reset input that allows for an external trigger to initiate a system reset, providing further flexibility and control to the user.

Applications:

The DS1706LEPA is suitable for a wide range of applications, particularly where system reliability and integrity are of paramount importance. These applications include embedded systems, portable devices, computers, and industrial control systems, among others.

Technical Specifications:

With a supply voltage range typically from 2.5V to 5.0V, the DS1706LEPA is versatile and can be integrated into various µP systems with different power requirements. The chip is offered in an 8-pin µSOP package, providing a compact footprint for space-constrained applications.

For engineers and system designers seeking a reliable microprocessor supervisory solution, the DS1706LEPA from Maxim Integrated offers the necessary features to maintain system stability and performance.
