Introduction of SG6520SZ

The SG6520SZ is an integrated circuit that acts as a system supervisor, providing system power management and protection as well as voltage monitoring. It is a high-performance, two-channel voltage monitoring device that monitors two power rails, monitoring their health and protecting them from overcurrent situations. The SG6520SZ is designed for use in high-current systems, and can handle power limits up to 15A. The device features an independent power-on-reset (PPS) signal and programmable reset thresholds of 0.8V to 5V, making it ideal for a wide range of applications.

Application Fields

The SG6520SZ is used in a number of industrial and consumer applications such as automotive, factories, and home appliances. The device is designed to meet the performance and safety requirements for a wide range of systems and applications. In automotive applications, the SG6520SZ is used in powertrain systems, providing reliable over-current protection for vital components such as battery, starter motor, alternator and fuel system. In factory automation, the device is used to monitor and protect high power circuits and equipment such as transformers, switches and motor controllers. It is also used in home appliances such as washers, dryers and dishwashers.

Working Principle

The SG6520SZ is a voltage monitoring device, and its working principle is based on the concept of current limiting. The device monitors two independent power rails and has programmable reset thresholds of 0.8V to 5V. The SG6520SZ also includes a voltage reference and an accurate comparator, which are used to detect when the monitored voltage reaches the programmed threshold. When the voltage on either of the two power rails reaches the programmed threshold, the SG6520SZ triggers a power-on-reset (PPS) signal. This signal is used to reset the system, allowing it to safely recover from an overcurrent situation. The device also features a two-step power-on reset sequence, which provides additional protection against catastrophic power supply events such as brownouts and overvoltage transients.

Conclusion

The SG6520SZ is a high-performance system supervisor and voltage monitoring device. It provides reliable overcurrent and overvoltage protection for a wide range of industrial and consumer applications including automotive, factories, and home appliances. The device has programmable reset thresholds of 0.8V to 5V, and includes a power-on-reset (PPS) signal and two-step power-on reset sequence. The SG6520SZ is a cost-effective and reliable solution for power management and protection.
