The Texas Instruments TPS3710DSER is a Resistor (R) monitored supervisor integrated circuit (IC) designed to keep a system in reset until all of the power supplies, voltage rails, and inputs reach and remain stable within an acceptable window. The TPS3710DSER is part of Texas Instruments\' Power Management IC (PMIC) - Supervisors lineup.

Overview

The TPS3710DSER is designed to monitor the positive voltage on a given voltage rail, and keep the system in reset until all of the requirements are met. It contains one set of threshold inputs, and one reset output. The voltage threshold of the TPS3710DSER is factory trimmed to 2.97V ±99mV. The TPS3710DSER accepts any analog input from 0.90V to 5.50V, but the voltage threshold remains constant at 2.97V ±99mV. The reset output is an active low open drain output that can be used to reset a microcontroller, microprocessor, and/or an entire system when all of the conditions are met.

Features and Benefits

The TPS3710DSER has several features and benefits that make it suitable for a variety of applications. First and foremost, the device\'s factory trimmed threshold ensures the accuracy of the voltage threshold, preventing false resets or erroneous system behavior. The device also contains a low current-draw, allowing it to maintain a very low quiescent current and preserve extremely low power consumption. Lastly, the device is offered in a small, space-saving package that allows for flexibility in board layout.

Applications

The TPS3710DSER is designed for use in a variety of different applications and can be used in systems that require power supply and voltage stability detection and reset. Additionally, the device can be used to ensure that the power supplies, voltage rails, and inputs remain within an acceptable window in order to prevent any system malfunction. Examples of applications that are ideally suited for the TPS3710DSER include LED lighting, communications systems, automotive systems, power management systems, industrial systems, and many more.

Working Principle

The TPS3710DSER\'s working principle is simple and efficient. It contains a comparator circuit with a factory trimmed threshold that is connected to a power supply or voltage rail. When the input voltage is below the threshold, the TPS3710DSER will keep the system in reset and the output asserted low. As the input voltage rises above the threshold and remains above for a predetermined time (tHYS), the reset will be released and the output will be deasserted. The TPS3710DSER will continue to monitor the input voltage and keep it within an acceptable window. If the voltage dips below the threshold again, the reset will be asserted and the cycle repeats.

Conclusion

The TPS3710DSER is a highly efficient and accurate resistor monitored IC designed for use in a variety of systems that require power supply and voltage stability detection and reset. The device has several features and benefits such as low quiescent current, factory trimmed voltage threshold, and small package size, which make it ideal for embedded and IoT applications. Its working principle is simple and effective, and will keep the system in reset until all of the requirements are met.
