The TPS3705-50DR is an integrated circuit from Texas Instruments designed for supervisory functions in microprocessor-based systems. It comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. The device is primarily used for monitoring supply voltage levels to ensure proper system operation and to prevent malfunctions due to undervoltage conditions.
Here are the pin functions:
1. VDD: Power supply input.
2. GND: Ground reference.
3. RESET: Active-low reset output. It triggers a reset condition when VDD falls below a predefined threshold.
4. MR (Manual Reset): A manual reset input. When pulled low, it activates the reset output.
5. WD (Watchdog Input): Monitors the activity to detect faults. It requires a periodic signal to prevent the reset output from being activated.
6. WDI (Watchdog Disable): Disables the watchdog function when tied to ground.
7. RESET: Active-high reset output.
8. NC (No Connect): Not internally connected, often used for mechanical stability.
This device is used in applications where ensuring the reliability and proper function of a system during power-up, shutdown, or brownout conditions is critical.
