The DS1708REUA from Maxim Integrated is a highly reliable MicroMonitor chip designed to safeguard system integrity during power cycling and brownout conditions. This compact and efficient device ensures that microprocessors and microcontrollers are reset to a known state during power-up, power-down, or any unexpected power failure, making it an essential component for a wide range of electronic applications.
The DS1708REUA operates by monitoring the system voltage and providing a reset signal to the connected microprocessor when the voltage drops below a predetermined threshold. This active-low reset signal is maintained for a minimum period after the voltage returns to an acceptable level, ensuring that the system has stabilized before normal operation resumes.
Key Features:
- Precision Monitoring: Features a precision temperature-compensated voltage reference and comparator circuit to monitor the status of the power supply.
- Programmable Reset Timeout: Offers a programmable reset timeout delay, which can be set by an external capacitor to meet specific system requirements.
- Low Power Consumption: Designed for low power consumption, this device is ideal for battery-operated systems.
- Manual Reset Input: Provides a manual reset input that allows for a reset to be triggered with an external pushbutton or logic signal.
- High Reset Output Drive Capability: The reset output can sink or source current, which is suitable for driving heavy loads such as LEDs or relays.
- Robust Packaging: Available in an 8-pin µSOP package, the DS1708REUA is both compact and robust, suitable for space-constrained applications.
This MicroMonitor chip is an excellent choice for managing system resets in personal computers, embedded systems, portable electronics, and other microprocessor-based systems. Its ability to ensure a safe and orderly system startup and shutdown protects against data corruption and hardware damage that can result from improper power supply levels.
With Maxim Integrated's reputation for quality and reliability, the DS1708REUA is a trusted solution for designers looking to improve the resilience and stability of their electronic systems.
