Introduction to the X5328S8IZ-4.5A Supervisors

The X5328S8IZ-4.5A is a new type of supervisor integrated circuit (IC) intended for automotive, communication and industrial hosts in applications where reliable system operations are critical. Unlike standard power management integrated circuits (PMICs) or supervisor ICs, the X5328S8IZ-4.5A provides additional features such as a flexible power supply design, low standby current, and fast active transition time.

Application Field

The X5328S8IZ-4.5A is highly suitable for automotive, communication and industrial system applications. It is specifically designed to enhance system reliability, reduce power consumption and provide stability in extreme operating conditions. As a supervisor IC, the X5328S8IZ-4.5A can detect voltage dropouts and safely power down the system when out-of-limit conditions are detected. It ensures system stability and robustness in operating environments where AC line-dropouts are present. It is also suitable for regulators and voltage monitors in battery-powered systems that require extended operating times.

The X5328S8IZ-4.5A supervisor IC is especially designed for data-centric systems, where the system operates in battery-powered and AC-powered modes. The X5328S8IZ-4.5A detects dropped power supplies and provides an instant low standby current mode with a fast power-up and power-down switchover. This ensures data preservation and system stability. In addition, the X5328S8IZ-4.5A can identify out-of-limit conditions, offering improved system robustness and reliability.

Working Principle

The X5328S8IZ-4.5A is a low voltage supervisor IC. It includes an on-chip voltage regulator and power monitoring features. The X5328S8IZ-4.5A works through an internal comparator and reference voltage which compare an external power supply voltage to a preset threshold. The comparator triggers an active transition with a fast transition time, either from standby to active mode or from active to standby mode, depending on the power supply voltage.

The X5328S8IZ-4.5A includes an adjustable sleep current. This is usually set to a predefined low value, low enough to extend the system\'s operating time on battery-powered mode. It continuously monitors the external power supply voltage, reducing power consumption while ensuring system stability.

The X5328S8IZ-4.5A integrated circuit also eliminates the need for external power supply monitoring components. The X5328S8IZ-4.5A requires no external components to function, and can be configured to work with a wide range of external power supply voltages. The X5328S8IZ-4.5A also integrates temperature monitoring, offering improved over-temperature protection.

The X5328S8IZ-4.5A offers selectable active/standby thresholds and independent reset functions. It provides an adjustable reset delay time from 0 to 16 seconds. It increases reliability by allowing the system to reset itself if an unexpected power cycle occurs. The X5328S8IZ-4.5A also offers an optional SCR & diode reverse supply protection, making it suitable for automotive environments.

Conclusion

The X5328S8IZ-4.5A supervisor IC is a reliable and versatile low voltage supervisor. It provides a wide range of features including low standby current, fast active transition, adjustable reset delay, independent reset functions, and temperature monitoring. The X5328S8IZ 4.5A is an ideal supervisor IC for automotive, communication, and industrial systems looking for improved reliability in operation.
