TPS3837K33DBVR Voltage Supervisor by Texas Instruments

The TPS3837K33DBVR is a highly precise voltage supervisor designed to maintain system integrity by monitoring the supply voltage in digital systems. Manufactured by Texas Instruments, a leader in semiconductor solutions, this device is an essential component for applications requiring reliable voltage supervision. It is commonly used in a variety of electronics, including portable devices, computers, and industrial equipment.

This voltage supervisor is specifically designed to monitor a 3.3V power supply, ensuring that the system operates within its intended voltage range. The TPS3837K33DBVR features a fixed-sense threshold voltage set at 3.07V, which is a critical level for many 3.3V-powered systems. When the supply voltage drops below this threshold, the supervisor outputs a reset signal, which can be used to reset the system or trigger an interrupt to prevent data corruption or other malfunctions.

The device comes in a compact 5-pin SOT-23 package, designated by the suffix 'DBVR', which is suitable for space-constrained applications. It offers a low quiescent current of only 1.5 µA, making it an energy-efficient choice for battery-operated devices. The low power consumption helps extend battery life and reduces the overall power demand of the system.

Moreover, the TPS3837K33DBVR provides a manual reset input, allowing for an external trigger to initiate a system reset. This feature is particularly useful for performing system diagnostics or for user-initiated resets. The device also includes a built-in delay before issuing a reset signal, ensuring that transient voltage dips do not cause unnecessary resets.

With a wide operating temperature range from -40°C to +85°C, the TPS3837K33DBVR is versatile and reliable in diverse environmental conditions. Its robust design and high accuracy make it an excellent choice for critical applications that demand consistent performance and minimal downtime.

For engineers and designers looking for a dependable voltage supervisor, the TPS3837K33DBVR from Texas Instruments offers the perfect combination of precision, low power consumption, and compact packaging.
