PMIC - Supervisors

The X4163PI is an advanced peripheral supervisor circuit which offers complete protection for I/O, core, and low voltage supply/start-up control. It works to maintain proper power sequencing by monitoring the supply voltages, signal conditions and other preset levels. In addition, the device provides system reset generation, temperature sense diagnostics, brown-out detection and many other system safety features.

The X4163PI can monitor the power supply voltages (VCC, VDD, VIO). It has programmable voltage range and delay times for various locations. It also provides a low voltage reset/wake-up output for system power sequencing, and a temperature sense output for fan control. Moreover, the X4163PI has a dedicated brown-out reset output which can be configured to respond to an under-voltage condition.

The X4163PI has a wide application field. It is used in computers, servers and networking systems, consumer electronics, automotive, industrial, and other applications. It can be used to maintain proper power sequencing and system reset generation, as well as providing temperature sense diagnostics and brown-out detection.

The working principle of the X4163PI is to monitor supply voltages, signal conditions, and other preset levels. For each voltage it can be programmed with an upper and lower limit, along with a programmable delay time. This information is then used to generate the appropriate power on/off sequences, system reset signals, temperature sense outputs, and brown-out detection. This ensures that the system is always powered on in the correct sequence, and that it is always functional and protected from any anomalies.

In conclusion, the X4163PI is a powerful peripheral supervisor circuit which offers complete power management and protection for I/O, core, and low voltage supply/start-up control. It has a wide application field, and its working principle ensures that the system is always powered on in the correct sequence, and that it is always functional and protected from any anomalies.
