PMIC Supervisors are an important type of passive componet – they watch over the system, makig sure that all operations are running properly. The TPS3710DSET is one of the most popular PMIC supervisors and has a range of applications in a wide range of industries, from consumer electronics to industrial electronics and automotive industries. Here, we look at the field of applications for the TPS3710DSET and its working principle.

Fields of Application

The TPS3710DSET is a low-dropout (LDO) supervisor with reset, and is suitable for use in a wide range of environments, including but not limited to consumer electronics, industrial electronics, automotive and medical industries. Consumer electronics applications include mobile phones and various other consumer electronics devices, while industrial applications include power supplies, industrial set-ups and systems, and automotive applications include security systems, infotainment systems and telematics. In addition, the TPS3710DSET is suitable for use in medical devices such as pacemakers and other implanted devices, imaging technologies and portable diagnostics.

Working Principle

The TPS3710DSET has five primary functions – overvoltage protection, undervoltage protection, reset control, microprocessor supervisor and power supply sequencing. Its overvoltage and undervoltage protection functions automatically monitor the input voltage and activate the reset pin when the voltage exceeds the set value. The reset control function also sets the reset delay time and can support manual reset. The microprocessor supervisor monitors the reset pin, enabling the reset circuit to function correctly even when the reset signal is altered.

The power supply sequencing function ensures that the necessary power supply is activated in the right sequence, thus maintaining the security and stability of the system. It also includes soft start and power-off sequencing, so that the necessary power sequence is done in a safe manner, avoiding abrupt shutdowns. Last, but not least, the TPS3710DSET\'s active low reset output ensures that the system restarts as soon as power is restored.

Conclusion

The TPS3710DSET is an LDO supervisor with reset and is suitable for use in a wide range of applications and environments. It has five primary functions – overvoltage protection, undervoltage protection, reset control, microprocessor supervisor and power supply sequencing – that enable it to maintain the stability, reliability and security of the system. Its active low reset output is an additional advantage, allowing the system to quickly restart after power is restored.
