Power Management Integrated Circuit (PMIC) – Supervisors refer to a class of semiconductor devices designed to monitor and control the operations of various electrical and electronic components. In particular, they help maintain safe electrical operations and prevent any harmful conditions from occurring in both home appliances and industrial equipment. This article will explore the application field and working principle of BD46262G-TR, a PMIC-Supervisor from Toshiba.

The BD46262G-TR is an integrated 3-channel voltage supervisor IC with monitor, reset and OR functions for maximizing the reliability of powered systems. This IC works by monitoring the supply voltage to determine its level and, if necessary, sends a reset signal. Each of the three channels can be set up separately to monitor different voltages and quickly detect and provide a reset when any of them falls below the set thresholds. This makes the IC well-suited for use in three-voltage system and allows users to save space and costs in their designs.

The application field of the BD46262G-TR is quite vast. It can be used in various industrial, automotive and home appliance applications, such as those found in air-conditioners, IT equipment, audio amplifiers and microprocessor-based systems. It is also well-suited for use in DC/DC converters and battery-backed applications. It can even be used to monitor and detect voltage discrepancies in AC/AC converters, motor controllers and lighting systems.

The working principle of the BD46262G-TR is quite simple. It uses comparators to measure any discrepancies in the voltage across the input pins and to judge it compared to the reference voltage. When the input voltage is found to be lower or higher than the reference voltage, the IC triggers a reset signal to the reset pins. This reset signal will then cut off any current flowing through the circuits, allowing them to reset and bring the device back to a safe operating condition.

In addition to providing reset signals, the BD46262G-TR also offers several protection functions. For instance, it prevents current overloading and hot plugging. Its overcharge protection circuit can detect and handle over-voltage situations and its thermal protection circuit uses the temperature sensing element built into the IC to detect any temperature rising and act accordingly. Furthermore, its over-current-limit protection restricts the output current to the limit set by using the external resistors.

In summary, the BD46262G-TR is a versatile and reliable integrated 3-channel voltage supervisor IC from Toshiba with monitor, reset, and OR functions for optimizing the reliability of powered systems. Its working principle is based on the comparison of input and reference voltage; it then sends a reset signal to the reset pins when discrepancies are detected. This makes it an ideal solution for a variety of applications, from industrial and automotive use to home appliances. Furthermore, its overcharge protection circuit, thermal protection circuit, and over-current-limit protection make it a very reliable and safe option for any system.
