BU4835G-TR Application Field and Working Principle

Power management integrated circuits (PMIC), such as the BU4835G-TR, are a type of integrated circuit (IC) used to monitor and control the voltage, current, and temperature of various types of circuitry. The BU4835G-TR a type of PMIC known as a supervisor which is designed to detect overvoltage and undervoltage conditions on a single rail. This device is commonly used to protect circuits from malfunction or damage due to supply voltage fluctuations.

The BU4835G-TR is a small temperature-compensating, single-channel supervisor IC, suitable for battery-powered systems, low-voltage or small-current systems, as well as power-sensitive applications. The device has a wide operating supply voltage range of 2.0 to 5.5V and is able to support a power supply range of 1.8V to 5.5V in the presence of short-term overvoltage conditions. This allows the circuit to be robust enough to protect complex circuits, while still being compatible with a wide range of voltage supply conditions.

The BU4835G-TR is designed to monitor one power source, with any overvoltage or undervoltage condition indicating a fault. An adjustable trip-point voltage sets the voltage threshold at which the device will transition from normal operating mode to a fault status. In this state, the device will usually trigger an interrupt signal or a shutdown of the system to prevent the circuit from malfunctioning or being damaged. The fault status may also be latched so that, after the fault condition has passed and the voltage has been restored to normal, the device will remain in a fault status until explicitly reset to restore the system. If desired, the overvoltage and/or undervoltage thresholds can be set independent of each other, with each provided a dedicated set of pins on the package.

The BU4835G-TR is an excellent solution for many applications that require voltage monitoring and protection. Its wide operating voltage range, adjustable trip point, and dual-level fault indicators make it suitable for a variety of applications. It is especially suited for battery-powered systems, low-voltage or small-current systems, wearable devices, network applications, and other power-sensitive applications.

The BU4835G-TR is an easy-to-use and effective solution for monitoring power supply voltages. Its features and wide operating voltage range make it well suited for use in many applications and give users confidence that their circuit is well protected from voltage fluctuations.
