BU4337FVE-TR is a voltage supervisor IC specifically designed for use in place of discrete 3-pin voltage supervisor components. This IC is ideal for commercial supervisory applications such as system sleep, system reset and feature enable pins, where replacing a discrete component with a single IC provides cost savings, design simplification and a more reliable system. The BU4337FVE-TR is built with a combination of advanced precision voltage monitoring/detector, timer, and output driver technologies, making it suitable for a broad array of commercial applications where reliability and tight tolerance tolerances are paramount.

The BU4337FVE-TR is a members of ICs of PMIC - Supervisors, which aim to provide stable, precise and reliable power supply for many applications such as PC, battery-powered handheld devices, embedded systems, and automotive systems. PMIC - Supervisors often require to work with a low power supply current. For this reason, the BU4337FVE-TR is generally implemented in areas where very low power is needed.

The BU4337FVE-TR is designed to monitor low voltage levels in a variety of applications. It features a low quiescent current pin compatible alternative to traditional three pin supervisor ICs, and offers three-pin functionality in a single package. Additionally, it has a low quiescent current that meets the needs of the most power-sensitive systems. The monitor is able to detect voltage changes and begin a reset action process depending on how much time is programmed and how many power cycles are permissible before the reset is initiated. Further, the monitor provides a latched output pin to allow for the system to recognize and process reset commands.

The BU4337FVE-TR features an internal timing circuit to detect input voltage transitions. When the voltage level is below a predetermined threshold, the monitor sends an active high output pulse as an indication of a power-on reset (POR). The monitor also has a power-good output that is asserted when the input voltage is within a preset threshold. This output can be used by the system to detect and process reset commands, or that the power is good and stable. Additionally, the monitor features a timer circuit which can be programmed to extend the output duration of the POR, allowing the system additional time to respond before resetting.

The BU4337FVE-TR has a wide operating temperature range and can operate from -40 to +85°C. The monitor has a shutdown mode and also a low-power sleep mode, which can reduce the quiescent current consumption. Further, the monitor has excellent noise immunity, making it suitable for sensitive applications such as those operating in noisy environments. It is also very reliable, and offers high accuracy and good linearity for reliable voltage monitoring.

The BU4337FVE-TR can be used in a variety of applications, including system sleep and system reset, battery monitoring, power supply monitoring, motor control, system shutdown, feature enable, and many other industrial, automotive and consumer applications. The monitor offers a cost-effective, reliable solution for any application requiring precise voltage monitoring.
