Introduction to PMIC - Supervisors

A Power Management Integrated Circuit (PMIC) - Supervisors are an Integrated Circuit (IC) which helps to oversee the power supply to an electronic device. This IC is usually a combination of several components such as voltage regulators, DC-DC converters, voltage references, and reset circuits. PMIC - Supervisors are designed to ensure that the power supply is not interrupted and keeps the device running properly. This article will discuss the Application field and Working Principle of the SP706REN-L/TR.

Application Field of SP706REN-L/TR

The application field of the SP706REN-L/TR is mainly focused on Point-of-Load (POL) converters and other low voltage supplies. The device is specifically intended for supervised power supply systems with a single output and is especially suitable for automotive applications. The Supervisor works by monitoring both the input power source and output voltage, and it can sense an over-voltage, under-voltage, short circuit, and brown-out conditions. The power supply system can also adjust its output voltage based on the supervisor’s input to ensure that the device is receiving the correct voltage level. This helps protect the electronic device from any potential damage due to excessive voltage or insufficient voltage.

Working Principles of SP706REN-L/TR

The SP706REN-L/TR application operates on a three-phase power supply, with each phase having a different voltage level and a common ground return. The primary function of the device is to monitor and analyze the incoming power source and output voltage, so that the output voltage can be adjusted if required. The device monitors the initial voltage levels and adjusts the output voltage if an under or over-voltage condition is encountered. A brown-out condition may also be sensed by the device and the output voltage is adjusted accordingly by the device. The device also monitors for a short-circuit or overload condition. In the case of a short-circuit, the output voltage is disconnected, and the device will wait until the short-circuit is resolved before allowing the output voltage to be connected again.The SP706REN-L/TR device also provides a power-failure output and a reset-request output. The power-failure output indicates that the output voltage of the device has dropped below a certain threshold and that the system is not operating correctly. This output can be used as an input to another system to ensure that the system is restarted, or to alert the user that there is an issue with the power supply. The reset-request output indicates that the system has learned of a potential failure, and that the system requires a reset in order to operate correctly.

Conclusion

The SP706REN-L/TR is a Power Management Integrated Circuit (PMIC) – Supervisors that is specifically designed for automotive applications. The device monitors and analyzes the incoming power source and output voltage in order to adjust the output voltage if required. The device provides a power-failure output and a reset-request output, and it can sense short circuits, under-voltages, over-voltages, and brown-out conditions. The SP706REN-L/TR is an ideal device for supervised power supply systems with a single output.
