Pinout
The TPS3824-25DBVR is a voltage supervisor IC from Texas Instruments. It comes in a SOT-23-5 package, which means it has 5 pins. The primary function of this device is to monitor supply voltage levels in electronic systems and provide a reset signal to ensure safe operation when the supply voltage falls below a specified threshold. The "25" in its name refers to a 2.5V threshold voltage.
Here's a brief overview of the pin functions:
1. VDD (Pin 1): Supply voltage input.
2. GND (Pin 2): Ground reference.
3. ~RESET~ (Pin 3): Active low reset output.
4. MR (Pin 4): Manual reset input, which can be used to trigger a reset externally.
5. WDI (Pin 5): Watchdog input for monitoring system operation.
The TPS3824-25 ensures that when the monitored voltage dips below 2.5V, it will assert a reset signal, preventing potential errors in microcontrollers or other digital systems.
