概要
Description
The TPS3824-50DBVR is a voltage supervisor or reset IC designed by Texas Instruments. It monitors the supply voltage in electronic systems and ensures that microcontrollers or processors operate correctly. This device generates a reset signal when the supply voltage drops below a specified threshold, in this case, 5.0V, ensuring that devices remain in a known state during power-up, power-down, or brownout conditions.
Key features include a precision voltage threshold, low supply current, and an active-low reset output that remains asserted for a fixed delay time after the voltage recovers. The TPS3824-50DBVR is housed in a small SOT-23 package, making it ideal for space-constrained applications. It is commonly used in various applications like computers, servers, automotive systems, and other embedded systems that require reliable voltage supervision for secure and stable operation.

Pinout
The TPS3824-50DBVR is a voltage supervisor IC from Texas Instruments. It comes in a 5-pin SOT-23 package. The function of this IC is to monitor the supply voltage in microcontroller and microprocessor systems and provide a reset signal when the voltage drops below a predefined threshold. This particular model, TPS3824-50, is designed for a 5.0V system.
Here’s a brief overview of the pin functions:
1. VDD (Pin 1): Power supply input. It monitors the voltage level.
2. GND (Pin 2): Ground reference for the device.
3. /RESET (Pin 3): Active-low reset output. It goes low when VDD falls below the threshold and stays low for a preset delay after VDD returns above the threshold.
4. MR (Pin 4): Manual reset input. Pulling this pin low will force a reset.
5. NC (Pin 5): No Connect. This pin is not connected internally and can be left floating or tied to ground.
This IC is commonly used to ensure reliable operation of digital systems by preventing operation at low supply voltages.
