Introduction

The ISL95712IRZ is a product from Renesas, belonging to its family of PMICs, voltage regulators and special purpose voltage regulators. The device is a high performance, low noise and precise load switch, designed to control high current flow between two power rails, while simultaneously providing supply and ground isolation between two circuits or components.

Application Field

The ISL95712IRZ offers a wide variety of applications. It is ideal for use in portable and embedded applications such as mobile phones, camera modules, MP3 players and other digital devices. It is also suitable for applications that require precise power control, such as those found in medical equipment.

Working Principle

The working principle of the ISL95712IRZ is based on detecting a voltage threshold, and then controlling the passage of current, regulating between two power rails. It has two threshold inputs, TIME and OFF, which are used to control the output voltage.

The TIME input determines how long the device will remain in the on-state before transitioning to the off-state. The OFF input is used to monitor the output voltage and will immediately transition the device to the off state if the connected output voltage falls below this value.

The ISL95712IRZ is capable of operating in a continuous, timed or manually activated mode depending on the configuration of the inputs. When in the continuous mode, the device will maintain the output voltage within a certain range, while when it is in the timed mode, the device will remain in the on-state for a given period of time. The manual activation mode allows the user to manually control the output voltage with a digital logic signal.

Conclusion

The ISL95712IRZ is a high performance and low noise load switch, designed to regulate the current between two power rails. It is ideal for use in portable and embedded applications and can be used to provide precise power control in medical applications. Additionally, its threshold inputs allow for configurable operation modes, such as continuous, timed and manual.
