Product Overview: TPS3823-50DBVTG4

The TPS3823-50DBVTG4 is a highly reliable supervisory circuit designed and manufactured by Texas Instruments. This device is engineered to monitor the system voltage in microprocessor (µP) systems, providing a crucial safeguard against power failures or low voltage conditions. It is an essential component for maintaining the integrity and stability of electronic systems, ensuring that all operations are performed within safe voltage levels.

Key Features

• Voltage Monitoring: The TPS3823-50DBVTG4 is equipped with a precision voltage sensor, set to monitor a threshold voltage of 5.0V. This feature is critical for systems that require consistent and reliable voltage levels to operate correctly.
• Power-On Reset Generator: The device includes an integrated power-on reset generator that asserts a reset signal when the monitored voltage falls below the threshold. The reset signal remains asserted for a fixed time interval after the voltage exceeds the threshold, ensuring the system has stabilized before resuming normal operation.
• Manual Reset: A manual reset input allows for an external trigger to initiate a system reset, providing additional control and security for system maintenance and troubleshooting.
• Watchdog Timer: The built-in watchdog timer serves as an independent system monitor, which can reset the microprocessor if it fails to stroke the watchdog within a preset time frame, indicating a system malfunction.
• Temperature Range: The TPS3823-50DBVTG4 operates over a wide temperature range, making it suitable for various industrial and commercial applications that may encounter extreme environmental conditions.
• Package: This device is available in a small, 5-pin SOT-23 package, which is ideal for space-constrained applications.
