TPS3825-33DBVTG4 - Voltage Supervisor IC by Texas Instruments

The TPS3825-33DBVTG4 is a highly reliable voltage supervisor integrated circuit (IC) designed and manufactured by Texas Instruments. This component is specifically engineered to monitor the system voltage in microprocessor (µP), microcontroller (MCU), and other digital systems, ensuring that the proper operation is maintained by providing a reset signal whenever necessary. The TPS3825-33DBVTG4 is an essential component for applications that require a high level of system reliability and resilience to voltage fluctuations.

This voltage supervisor IC has a fixed-sense threshold voltage of 3.3V, which is ideal for systems operating at this voltage level. The device features a built-in delay time after becoming active, which provides the system with enough time to stabilize before it starts operating again. This delay can be very useful in preventing system errors during power-up, power-down, or brown-out conditions.

The TPS3825-33DBVTG4 comes in a compact SOT-23-5 package, making it suitable for space-constrained applications. It has a temperature range of -40°C to +85°C, allowing it to operate reliably in a wide range of environmental conditions. This makes it an excellent choice for industrial, automotive, and consumer electronics where temperature variations are common.

Key features of the TPS3825-33DBVTG4 include a low supply current, which is critical for battery-powered devices, and a manual reset input. The manual reset input allows for a system reset to be triggered with an external signal, providing an additional layer of control. The device also offers a reset time delay of 200ms, ensuring that the system has ample time to return to a stable state before resuming operation.

In summary, the TPS3825-33DBVTG4 voltage supervisor IC by Texas Instruments is a robust and essential component for maintaining system stability and reliability. Its precise voltage monitoring capabilities and built-in delay features make it an ideal choice for a wide range of applications that require consistent system performance and resilience to power irregularities.
