X4163S8-4.5A

PMIC - Supervisors are versatile integrated circuits used to accurately monitor and control power-supply systems in a wide variety of high-end applications.

The X4163S8-4.5A is one type of supervisory IC used to provide high-quality voltage monitoring and reset application. It has a variety of features and functions, such as programmable reset delay and reset timeout, manual and automatic reset, and reset timeout counter. This IC can also be used to monitor multiple power supplies.

The X4163S8-4.5A application field ranges from telecom equipment to personal computers, server systems, and instrumentation. It is also used in automotive and industrial equipment. Its applications range from voltage monitoring, reset sequencing and sequencing, overvoltage protection, and system reset.

The X4163S8-4.5A working principle is to set the supply voltage threshold level, and the IC will monitor the voltage constantly. When the voltage drops below or exceeds the indicated threshold, it will issue a reset, or can be configured for interrupt mode. The reset delay, or reset timeout, can be adjusted as desired, and the reset output can be run as active-low, active-high, or open-drain.

The built-in security features in the X4163S8-4.5A supervisor IC include a manual reset input, a manual reset output, and a differential-mode power supply monitoring. Manual reset input can manually reset the IC, while the manual reset output can be used to indicate the reset status. It also incorporates a pulse count (PC) mode to reset the supply after a certain number of pulses from the internal clock. The differential-mode power supply monitoring helps protect the system from overvoltage and undervoltage, and can detect small changes in power supply voltage.

The X4163S8-4.5A IC has built-in ESD protection and can withstand voltage spikes up to 4500V. It is available in five-terminal SIP and DIP packages, and comes in versions with 2.3V, 2.7V, 3.0V, and 4.5V voltage thresholds.

In conclusion, the X4163S8-4.5A is a high-performance, versatile supervisory IC used to provide high-quality voltage monitoring and reset applications. It can be used to monitor multiple power supplies, and has a variety of features and functions for enhanced protection and control. It is useful for a variety of applications in telecom, automotive, industrial, and personal computer fields.
