Features
1. Voltage Monitoring: It monitors the system's power supply and asserts a reset when the voltage drops below a preset threshold, ensuring reliable system startup and operation.
2. Manual Reset Input: Allows external control over the reset signal, providing additional flexibility for system designs.
3. Active-Low RESET Output: Offers a stable logic low output when the monitored voltage is below the threshold or during a manual reset, ensuring connected devices are properly reset.
4. Reset Timeout Period: Features a defined reset timeout period, allowing adequate timing for the system to stabilize before operations resume.
5. Low Supply Current: Designed for efficiency with minimal power consumption, contributing to longer battery life in portable applications.
6. Package and Temperature Range: Available in compact packaging suitable for space-constrained applications, and operates over a wide temperature range, making it versatile for various environments.
These features make it suitable for ensuring the stability and reliability of microprocessor-based systems.
Pinout
- Pin Count: The MAX6747 generally comes in a 4-pin package.
- Pin Functions:
1. VCC: Power supply input.
2. GND: Ground.
3. RESET: This output pin goes low when the monitored voltage drops below the specified reset threshold and remains low for a specified reset timeout period after the voltage returns above the threshold.
4. MR (Manual Reset Input): An input that allows an external push-button or signal to trigger a reset manually.
This configuration ensures reliable operation by monitoring and controlling the voltage levels, thereby safeguarding microprocessors and other devices from voltage-related issues. Always consult the datasheet for detailed specifications and operational guidance.
