Overview of TPS3823-50DBVR

The TPS3823-50DBVR is a highly reliable supervisory circuit designed and manufactured by Texas Instruments. This compact device is essential for monitoring the power supply and system health of microprocessors (µPs), microcontrollers (MCUs), and other digital systems. With its precision voltage detection and watchdog timer functionality, it ensures that systems operate within safe parameters, enhancing system reliability and preventing data corruption.

Key Features

• Voltage Supervision: The TPS3823-50DBVR offers a fixed-sense threshold voltage of 4.55V, which is ideal for 5V systems. This threshold level ensures that the device can accurately detect under-voltage conditions, signaling the system to take appropriate action to avoid malfunction.
• Watchdog Timer: A built-in watchdog timer serves as a system check, ensuring that the system does not hang or operate erratically. If the watchdog timer is not reset within a preset time frame, it triggers a system reset, which helps in maintaining system integrity.
• Manual Reset: The device features a manual reset input that allows for an immediate reset initiation, giving users direct control over the system's reset conditions.
• Power-On Reset Generator: The automatic power-on reset generator ensures that the system's microprocessor starts up in a known state, preventing any erratic behavior from the outset.
• Temperature Range: It operates over a wide temperature range, from -40°C to +85°C, making it suitable for various industrial and commercial applications.
• Small Form Factor: Encased in a 5-pin SOT-23 package, the TPS3823-50DBVR is designed for space-constrained applications, providing essential monitoring capabilities without occupying significant board space.

Applications

The TPS3823-50DBVR is versatile and can be used in a wide array of applications. It is particularly useful in systems that require a high degree of reliability and operational stability, such as:

• Portable Electronics
• Networking Equipment
• Computers and Computer Peripherals
• Industrial Controls
• Embedded Systems

With its robust feature set and Texas Instruments' reputation for quality, the TPS3823-50DBVR is an excellent choice for system designers looking to enhance the reliability and safety of their electronic products.
