The TPS3851G30EDRBR from Texas Instruments is a highly precise voltage supervisor designed to ensure the reliability and proper operation of microprocessors, microcontrollers, and other voltage-sensitive devices. This integrated circuit (IC) monitors the system voltage and provides a reset signal to the host device when necessary, helping to prevent system failure due to undervoltage conditions.

Key Features

• Adjustable Threshold Voltage: The TPS3851G30EDRBR comes with an adjustable threshold voltage feature, allowing designers to set the undervoltage detection level to suit the specific needs of their application.
• Low Quiescent Current: With its low quiescent current consumption, this voltage supervisor is an excellent choice for battery-powered and low-power applications, helping to extend the overall battery life of the system.
• High Accuracy: The device offers high threshold accuracy, which is crucial for systems that require precise voltage monitoring to maintain operational integrity.
• Manual Reset Input: A manual reset input is provided, allowing for an external signal to initiate a system reset, offering additional flexibility and control for system designers.
• Watchdog Timer: It includes a built-in watchdog timer that can be used to monitor the operation of the microprocessor or microcontroller, ensuring that the system does not hang or become unresponsive.
• Power-On Reset: The IC generates a power-on reset signal for a fixed delay time after supply voltage VDD reaches the threshold voltage, ensuring the system starts up correctly every time.
