The X4163S8I supervisor IC is a popular supervisors IC for on-board power systems and other embedded applications. It can control a wide range of regulated outputs from 1.8 V to 5.5 V, and can easily integrate into existing designs due to its small size, low power requirements and minimal external components. This article will discuss the basics of the X4163S8I supervisor and its applications, as well as its working principle.

Overview

The X4163S8I supervisor is a small, low-power supervisor IC that maintains system power integrity and provides power sequencing and fault protection for embedded systems. It is designed for use on a single 3.3 V supply and features an on-chip 1.8 V LDO regulator that can provide up to 1A of output current. The X4163S8I can provide up to 8 regulated outputs, with adjustable voltage settings from 1.8 V to 5.5 V. In addition, the IC has a programmable voltage-to-time conversion timer and a programmable reset timer.

The X4163S8I is designed to protect against reverse polarity, over-voltage, under-voltage, thermal runaway, and other system fault conditions. It also has a self-time capability, which allows the supervisor to execute various system operations in the event of a fault condition. The supervisor has an on-chip status register, which can be queried and set from the microcontroller to control the state of the reset and power pins. The IC also includes an on-chip oscillator for precise timing control.

Application Field

The X4163S8I supervisor IC is suitable for a wide range of applications that require robust system power integrity and fault protection. It is commonly used in embedded systems, rack-mounted power supplies, and other onboard power systems. Due to its small size, low power requirements, and minimal external components, it can easily be integrated into existing designs.

The X4163S8I can also be used in automotive applications, such as engine and lighting controllers. The supervisor\'s fault protection can quickly detect over-voltage, under-voltage, and thermal runaway conditions and take steps to protect the system from these faults. The supervisor can also be used to control engine start/stop, LED lighting systems, and other automotive components.

The X4163S8I can also be used in industrial applications, such as PLCs, automation equipment, and test & measurement systems. It can be used to protect the system from power glitches and over-voltage conditions, and its programmable voltage-to-time conversion timer can be used to precisely control system operations.

Working Principle

The X4163S8I works by monitoring the system voltage and taking action to protect the system if a fault condition is detected. When the voltage on VCC rises above the preset over-voltage threshold, the supervisor will take steps to protect the system. First, it will assert its reset pin to force the system controller into a reset state. The supervisor will also latch off its regulated power outputs, preventing power from being supplied to the system components. When the over-voltage condition has passed, the supervisor will unassert the reset pin and allow the system to resume normal operations.

When the voltage on VCC falls below the preset under-voltage threshold, the supervisor will again take steps to protect the system. First, it will assert its reset pin to force the system controller into a reset state. The supervisor will also activate its precision timer circuit and latch off its regulated power outputs. This will prevent too much current from being supplied to the system until the under-voltage condition has passed and the power can be safely restored.

The X4163S8I also has a self-time capability, which allows the IC to initiate system operations in the event of a fault condition. The supervisor can be programmed to execute various system operations, such as powering down equipment, resetting devices, and disabling outputs, in order to protect the system from further damage.

Conclusion

The X4163S8I supervisor IC is a popular supervisors IC for on-board power systems and other embedded applications. It can control a wide range of regulated outputs from 1.8 V to 5.5 V, and can easily integrate into existing designs due to its small size, low power requirements and minimal external components. The IC provides robust system power integrity and fault protection, as well as a self-time capability for precise timing control. The supervisor is suitable for a wide range of applications, including embedded systems, automotive applications, and industrial applications.
