TPS3823-33DBVR

The TPS3823-33DBVR is a voltage supervisor from Texas Instruments designed to monitor the supply voltage in microcontroller and microprocessor systems. It ensures reliable operation by resetting the system during power-up, power-down, and brownout conditions. The device is specifically tailored for applications requiring a 3.3V supply, where it monitors the voltage and generates a reset signal if the voltage drops below a specified threshold, typically 2.93V for the TPS3823-33 variant.
Key features include a precision voltage threshold, low supply current, and a push-pull reset output. It provides a manual reset input and a fixed reset delay time of 200ms. This supervisor is housed in a small SOT-23-5 package, making it suitable for space-constrained applications. Typical applications include embedded systems, personal computers, and portable devices. The TPS3823-33DBVR enhances system reliability by preventing undefined system states due to inadequate supply voltage levels.

The TPS3823-33DBVR is a voltage supervisor IC from Texas Instruments. It is designed to monitor supply voltages in microprocessor systems and provide a reset signal to the microprocessor during power-up, power-down, and brownout conditions.
The TPS3823-33DBVR comes in a 5-pin SOT-23 package. The pin functions are as follows:
1. Pin 1 (RESET): Active-low reset output; it is driven low when the monitored voltage (VDD) drops below the specified threshold.
2. Pin 2 (GND): Ground connection.
3. Pin 3 (MR): Manual reset input; pulling this pin low externally causes the RESET to assert.
4. Pin 4 (VDD): Supply voltage input; the voltage that is monitored by the supervisor.
5. Pin 5 (NC): No internal connection; typically not used.
The device is configured to monitor a 3.3V supply voltage, and the RESET output is held low when the VDD falls below approximately 2.93V.
