X4165S8 is a high accuracy supervisor designed based on the advanced CMOS technology. It is a three pin voltage supervisor that contains a precision voltage detector, a TTL-compatible reset output, and a manual reset input. The X4165S8 offers high voltage accuracy and low supply current to meet the demands of the regulated power supplies and modern systems equip with high-density circuit boards. It has become the popular choice for many system designs with small form factor and high temperature operating applications.

The X4165S8 is mainly used for design, power on reset, microprocessor resetting and fail safe application. It provides microprocessor reset function or system failure signal in applications of computers, controllers, microcontrollers, instrumentations and other digital equipments. The X4165S8 is commonly used in the application fields such as industrial control, telecommunication power systems, consumer electronics, industrial automation and aerospace.

The X4165S8 works by sensing the voltage level at its reference pin and comparing it with its normal voltage threshold. An active-low open collector output is available to indicate the result of this comparison which can be used to detect abnormal conditions. When the reference voltage exceeds the normal value, the output will be inactive, otherwise the output is active. If the reference voltage is higher than the trip level, the reset output will automatically handle the reset signal until the voltage returns to its normal value.

The X4165S8 provides a wide voltage range because of its low supply voltage. It has one manual reset input and one adjustable reset output. It offers power up reset, power down reset and fail safe reset in a wide frequency range from DC to 1MHz. It also has built-in hysteresis, low supply current and low input bias current for better stability. The X4165S8 also has multiple protection functions such as open collector protection and reverse voltage protection for improved safety and reliability.

The X4165S8 offers superior performance in its class with its accuracy, low supply current and small form factor. It has been used in many systems that require reliable reset signals and a wide voltage range. It is a great choice for systems that require large number of reset signals to operate. Its reliability and high accuracy make it a popular choice in the PMIC - Supervisors application field.
