Overview of Texas Instruments TPS386040RGPT

The TPS386040RGPT is a highly sophisticated quad supply voltage supervisor (SVS) designed by Texas Instruments (TI) to ensure the reliability and proper operation of microprocessor (µP) systems, field-programmable gate arrays (FPGAs), and other digital systems. This device is a part of TI's extensive power management integrated circuits, designed to monitor multiple supply voltages.

Key Features

• Quad Voltage Monitoring: The TPS386040RGPT can monitor up to four different voltage rails, making it an ideal solution for complex systems that require multiple power domains to be supervised.
• Adjustable Thresholds: Each of the four supervisors has an adjustable voltage threshold, which can be set using external resistors. This allows for precise voltage monitoring tailored to specific system requirements.
• Low Quiescent Current: With a low quiescent current of 10 µA (typical), it minimizes power consumption when in operation, making it suitable for power-sensitive applications.
• Programmable Delay Time: The device features programmable time delay for reset signals, providing designers with flexibility to set the delay according to system needs.
• Manual Reset (MR) Input: A manual reset input allows for a system reset to be triggered externally, providing additional control over the reset functionality.
