Description
Key features include:
1. Reset Output: It generates a reset signal when the supply voltage drops below a preset threshold or when the watchdog timer is not serviced within a predetermined time frame.
2. Supply Voltage Monitoring: It monitors the system's supply voltage and asserts a reset if the voltage falls below a specific level (typically 4.65V).
3. Watchdog Timer: Ensures that the microprocessor is functioning properly by requiring periodic toggling of a pin to avoid system resets.
4. Manual Reset Input: Allows an external pushbutton or signal to reset the system manually.
The device is commonly used in applications where reliable reset and power supervision are critical, such as in embedded systems, computers, and automotive electronics.
Equivalent
1. TPS3823-33 from Texas Instruments
2. MCP1316 or MCP1318 from Microchip Technology
3. CAT705 from ON Semiconductor
4. DS1231 from Dallas Semiconductor
5. ADM706 from Analog Devices
These alternatives offer similar voltage monitoring, reset functionality, and watchdog timer features critical for microprocessor systems. Ensure to check the specific parameters to match your application's needs.
Features
1. Supply Voltage Supervision: Monitors the supply voltage and provides a reset signal when the voltage drops below a predefined threshold, ensuring safe microprocessor operations.
2. Reset Output: Provides an active-low reset signal to reset the microprocessor during power-up, power-down, or brownout conditions.
3. Manual Reset Input: Allows a user-initiated reset by providing an external input.
4. Watchdog Timer: Ensures the microprocessor is operating correctly by requiring periodic toggling; otherwise, it triggers a reset if the microprocessor fails to respond in time.
5. Low Voltage Thresholds: Offers multiple threshold options to suit different system requirements.
6. Small Package: Available in a compact 8-pin SO package, making it suitable for space-constrained applications.
These features make the MAX706TESA ideal for improving reliability and performance in microprocessor-based systems.
Pinout
1. GND (Pin 1): Ground reference for the device.
2. VCC (Pin 2): Power supply input that monitors the voltage level.
3. \(\overline{\text{RESET}}\) (Pin 3): Active-low reset output that indicates when the monitored voltage is below the threshold.
4. RESET (Pin 4): Active-high reset output.
5. MR (Pin 5): Manual reset input, active-low. Pulling it low can trigger a reset.
6. WDI (Pin 6): Watchdog timer input. Regularly toggling this pin prevents the watchdog timer from resetting the system.
7. WDO (Pin 7): Watchdog timer output, active-low. It goes low if the watchdog timer is not serviced within the specified interval.
8. VOUT (Pin 8): Output providing a regulated voltage source.
These pins together ensure that the system operates reliably by providing reset signals, monitoring voltage levels, and managing the watchdog timer.
