TPS3825-33DBVR

The TPS3825-33DBVR is a voltage supervisor or reset IC manufactured by Texas Instruments. It is designed to monitor the supply voltage in electronic systems and ensure that the system operates correctly by generating a reset signal when the voltage falls below a specified threshold. The '33' in its name indicates that it is tailored for monitoring a 3.3V supply voltage.
Key features of the TPS3825-33DBVR include a low supply current, a high precision voltage threshold, and an open-drain reset output. The device is designed to assert a reset signal when the monitored voltage drops below the threshold, and it maintains this reset until the voltage returns and stabilizes above the threshold level for a predefined period. The device typically features a fixed delay time for the reset signal, promoting stability and allowing the system to establish normal operation before deasserting the reset signal.
This IC is commonly used in microprocessor and microcontroller applications, ensuring reliable operation by preventing erroneous behavior during brownout conditions, power-up, and power-down sequences. It is housed in a small SOT-23 package, making it suitable for compact designs.

8. Wide Operating Temperature Range: Functions reliably over a temperature range of -40°C to +85°C, making it suitable for various environmental conditions.
These features make the TPS3825-33DBVR an efficient choice for safeguarding microprocessor systems by ensuring they reset correctly during power-up, power-down, or brownout conditions.

The TPS3825-33DBVR is a microprocessor supervisory circuit from Texas Instruments. It comes in a SOT-23-5 package type, which is a small outline transistor package with five leads.

The TPS3825-33DBVR is a voltage supervisor IC from Texas Instruments, designed to monitor supply voltages in microprocessor systems. It features a 5-pin package. Here are the pin functions:
1. VDD (Pin 1): Power supply input pin. This is where the supply voltage is applied to the device.
2. GND (Pin 2): Ground pin. It is the common ground reference for all the other pins.
3. MR (Pin 3): Manual Reset input. This is an active-low input that allows a user to manually trigger a reset. If driven low, it will initiate a reset regardless of the VDD voltage level.
4. RESET (Pin 4): Reset output. It is an active-low output that signals when the monitored voltage is below the threshold level or when the MR pin is asserted.
5. NC (Pin 5): No Connect. This pin is typically not connected internally and can be left unconnected or connected to ground for stability.
The TPS3825-33DBVR is used primarily for ensuring microprocessor systems reset correctly under low voltage conditions.
