PMIC - Supervisors: DS1833-15/T&R Application Field and Working Principle

PMIC (Power Management Integrated Circuit), or PMU (Power Management Unit), is a primary component of today’s sophisticated power electronics systems. It houses a wide array of external components such as voltage regulators, voltage detectors, converters, and supervisors. The supervisors within it supervise the power system, detect any indication of a fault or abnormality in the system, and respond with corrective actions. The DS1833-15/T&R, an innovative power system supervisor, is one such type of supervisor, which was introduced by Maxim Integrated in January 2021. This article provides a detailed overview of the DS1833-15/T&R, its application fields, and its working principle.

Overview

The Maxim Integrated DS1833 Power System Supervisor is a dual-channel, ultra-low power supervisor that can accurately monitor multiple voltage rails in both DC and AC systems. It includes an over-voltage (OV) detection, low-voltage (LV) detection, and watchdog timer (WDT) functions, providing comprehensive protection against transient and over-voltage conditions. The device also includes an on-chip temperature sensing capability and other various protective functions. In addition, the device consumes only 8μA of typical power during monitoring and 225nA of typical low-power standby current.

Application Field

The DS1833-15/T&R is designed for use in a variety of applications that require accurate monitoring of multiple voltage rails. These include PC motherboards and video cards, graphics cards, gaming devices, computer memory modules, and high-end gaming consoles such as console gaming systems. The device is also suitable for industrial applications such as automotive, medical, and other industrial control systems. The voltage detection accuracy of the DS1833-15/T&R makes it ideal for use in DC/DC converters and other power conversion applications, as well as battery management systems.

Working Principle

The DS1833-15/T&R utilizes several key protection techniques to protect circuit components from power surges, overvoltages, and other transient conditions. These techniques are used to detect changes in the voltage levels of monitored rails, and respond accordingly. The device includes an over-voltage (OV) detection system, which monitors the input/output voltage level of the device and sends an alert if it detects an over-voltage condition. The device also features a low-voltage (LV) detection system that monitors for changes in the input/output voltage levels. If a low-voltage condition is detected, the device will send out an alert. Additionally, the device features a watchdog timer (WDT) system, which can be used to detect any sudden changes in the system temperature and protect the system components from thermal damage. It also includes an on-chip temperature sensing function which can be used to track changes in the system temperature.

Aside from its protection functions, the DS1833-15/T&R also features a set of sophisticated functions to further enhance its operation. These features include output voltage monitoring and adjustment, as well as output ripple detection. The device also has programmable voltage and temperature thresholds, enabling it to accurately detect any changes in the input/output voltage levels and temperature. Additionally, the device features temperature compensation and temperature auto-reset capability, which can be used to maintain the voltage level of the monitored rails.

Conclusion

PMICs provide better protection for the components of a power system. The DS1833-15/T&R is a type of dual-channel ultra-low power supervisor which includes a range of protection functions including an OV detection system, an LV detection system, and a WDT system. It also has various sophisticated functions such as voltage and temperature monitoring, as well as output voltage auto-reset capability. All these features make the DS1833-15/T&R an ideal choice for applications requiring accurate monitoring of multiple voltage rails, such as PC motherboards and video cards, graphics cards, gaming devices, computer memory modules, automotive, medical, and other industrial control systems.
