Description
Equivalent
1. MCP130T-450I/TT - from Microchip
2. DS1233DZ-5 - from Dallas Semiconductor (Maxim Integrated)
3. STM706T - from STMicroelectronics
4. ADM811TARTZ - from Analog Devices
5. TPS3823-33DBVR - from Texas Instruments
These equivalents may have different features, so it's important to verify compatibility with your application's specific requirements.
Features
1. Voltage Monitoring: It monitors three supply voltages, including a primary supply voltage, and provides reset signals when voltage levels drop below predefined thresholds.
2. Reset Functionality: It provides a reset output to prevent code execution errors during power-up, power-down, or brownout conditions.
3. Watchdog Timer: The device includes a watchdog timer to ensure the microprocessor is functioning correctly, resetting it if it fails to toggle the watchdog input within a preset timeout period.
4. Manual Reset Input: A manual reset input allows external push-button reset capability.
5. Low Supply Current: It operates with low supply current, making it suitable for battery-powered applications.
6. Package: The MAX708ESA+T is available in an 8-pin SOIC package, which is compact and suitable for space-constrained designs.
These features make the MAX708ESA+T ideal for ensuring system reliability in various embedded and digital applications.
Pinout
1. VCC (Pin 1): Power supply input.
2. GND (Pin 2): Ground reference.
3. RESET (Pin 3): Active-low reset output. It asserts when VCC is below a specified threshold or when a manual reset occurs.
4. RESET (Pin 4): Active-high reset output, similar functionality to the RESET pin.
5. MR (Pin 5): Manual reset input. A low signal on this pin asserts the reset outputs.
6. WDI (Pin 6): Watchdog input. A timer function that requires periodic toggling by the microprocessor to avoid a reset.
7. PFO (Pin 7): Power-fail comparator output. It indicates power failure when an external voltage falls below a specified threshold.
8. PFI (Pin 8): Power-fail comparator input. Used to monitor an unregulated power supply.
The MAX708ESA+T ensures reliable operation by generating resets during power anomalies and monitoring system activity through its watchdog and power-fail functions.
