PMIC Supervisors are integrated circuit devices used to monitor and control the power supply in an electronic system. The TL7702ACP/A is a simple and cost-effective PMIC supervisor with excellent performance and low standby current. It is suitable for portable and low power applications.

The TL7702ACP/A can be used as a replacement for manual resetting circuits in power supplies and electronic designs. It provides protection against undervoltage, overvoltage, and open circuit conditions. It also provides automatic reset and power reset delay, which makes it suitable for a variety of system power applications. The low current consumption of the TL7702ACP/A makes it suitable for use in battery-powered, portable devices.

The TL7702ACP/A has two operating modes. It can be used as a power-on reset (POR) controller, or as an under-voltage reset (UVR) monitor. In POR mode, the TL7702ACP/A monitors the power supply voltage for a user-defined time after power-on. If the voltage is lower than the specified minimum threshold during this time, the device will generate a reset signal and reset the system. In UVR mode, the device will reset the system if the voltage drops below the specified minimum threshold. The reset signal is deasserted once the voltage returns to normal operating levels.

The TL7702ACP/A has configurable overvoltage protection. It can be programmed with a maximum allowed output voltage and will generate a reset signal if the voltage is higher than the programmed limit. This feature is particularly useful when the system is powered by a wide range of voltages, such as when a device is being charged or used in a mobile application.

The TL7702ACP/A has an adjustable reset delay. This allows the system to be reset if the power supply voltage is outside the specified operating range for more than the preset time. The reset delay can be set to any value between 0.1 ms and 8.8 s. The delay is adjustable using the on-chip resistor.

The TL7702ACP/A also has a user-programmable power-on reset output (POROUT) pulse width. This can be set to any value between 1 ms and 8.8 s. This feature is useful for providing accurate timing of the power-on reset action in applications such as microcontrollers where tight control over reset timing is required.

The TL7702ACP/A is a highly versatile and cost-effective PMIC supervisor that provides excellent protection and performance for electronic systems. It can be used in a wide range of applications, including battery-powered and portable devices, and can be easily configured to meet the specific needs of the system.
