Overview
Description
Key specifications include a threshold voltage of 3.3V, low supply current, and a push-pull reset output. The TPS3824-33DBVR is housed in a small SOT-23 package, making it ideal for space-constrained applications. It has a typical active current consumption of 9 µA, ensuring minimal power draw. The reset output remains active for a specified delay period after the voltage returns to acceptable levels, allowing the system to stabilize before resuming normal operations. This IC is used in various applications, including battery-powered devices, embedded systems, and industrial equipment, to enhance reliability and prevent data corruption or hardware malfunctions.

Features
1. Voltage Monitoring: It monitors a fixed threshold of 3.3V, ensuring the system operates within safe voltage limits.
2. Precision: Offers high accuracy in voltage detection with a typical threshold accuracy of ±2%.
3. Reset Function: Provides a reset signal to the microcontroller or processor when the monitored voltage falls below the threshold, ensuring reliable system startup and operation.
4. Low Supply Current: Operates with a very low quiescent current, making it suitable for battery-powered applications.
5. Compact Package: Available in a small SOT-23 package, ideal for space-constrained designs.
6. Wide Temperature Range: Functions over a temperature range of -40°C to +85°C, suitable for various environmental conditions.
7. Push-Pull or Open-Drain Output: Comes with different output configurations to suit specific design requirements.
These features make the TPS3824-33DBVR an efficient and reliable choice for voltage supervision in embedded systems.
Pinout
1. GND (Ground): Provides the ground reference for the device.
2. MR (Manual Reset Input): An active-low input that allows an external reset signal to be applied.
3. RESET: An active-low output that signals a reset condition when the supply voltage drops below a specified threshold or when MR is asserted.
4. VDD (Supply Voltage): Connects to the monitored supply voltage. The IC monitors this supply voltage and asserts RESET when VDD falls below the threshold.
5. NC (No Connect): Typically not connected; ensures correct pin alignment.
The TPS3824-33DBVR is specifically tailored for systems requiring a reset signal when the supply voltage drops below 3.3V. It helps prevent microprocessor damage or malfunction by ensuring that reset conditions are met before normal operation resumes.
