X5083V8IZ-2.7 is a popular PMIC-Supervisors product from the ROHM Semiconductor family. It is a precision timebase chip that provides a combination of features for a wide range of applications.

The X5083V8IZ-2.7 integrates three key functions - voltage detection, voltage regulator and temperature protection - into one device. It is used for voltage detection and regulation for digital circuits and as a timebase for various applications, including LED DRAM and flash memory. The device features an on-chip voltage detector, voltage regulator and temperature protection circuit, providing these functions with excellent accuracy and reliability.

The X5083V8IZ-2.7 is designed with a switch mode control circuit to provide a voltage detection function and a built-in thermal protection circuit to protect the device from over-current conditions. The voltage detector detects the voltage of an external circuit, and the output of the voltage detector is sent to an upper limit (UL) or lower limit (LL) setting circuit, with the output of that circuit setting the asymptotic voltage of the circuit.

The regulator circuit has a hysteretic width control circuit to accurately control the output voltage. It also features a temperature protection circuit to protect the device from excessive temperature conditions. This function is monitored and checked by the supervisor circuit and can be shut down if the temperature rises above a user-defined setting.

The device has an adjustable threshold voltage of either 1.2V or 2.4V, and it operates over an operating temperature range of -40°C to +125°C. The device also features a power-on reset (POR) function that resets the operating state of the circuit on power-up. The POR function is enabled by default and can be disabled by writing the status bit.

The X5083V8IZ-2.7 is suitable for battery-type applications, such as mobile phones and portable music players. It is also suitable for automotive applications with its wide operating temperature range and excellent EMC/EMI performance, making it an ideal choice for a variety of applications.

In conclusion, the X5083V8IZ-2.7 is a highly reliable and versatile PMIC-Supervisors product from the ROHM Semiconductor family. It provides excellent accuracy, reliability and temperature protection functions, making it an ideal choice for a variety of applications, from mobile phones to automotive applications.
