Introduction to BU4332FVE-TR

The BU4332FVE-TR is a precision reset IC (Integrated Circuit) from ROHM Semiconductor. It is a power management IC (PMIC) that belongs to the Supervisors family. As mentioned before, this IC is a precision reset IC, specially designed to provide industrial grade performance. The integrated reset circuit in this IC provides high accuracy reset detection while maintaining low power consumption.

Applications of BU4332FVE-TR

The BU4332FVE-TR is mainly used in embedded systems and industrial control systems. It can provide reset (power-on reset) and over-voltage detection (OVP) to ensure reliable operation of micro-controllers, processors, debugging and other power management related operations.The BU4332FVE-TR is suitable for a wide range of applications due to its features like high accuracy detection of reset signals, low power consumption, wide operating temperature range, low I/O pin count, and fast response time.

Features of BU4332FVE-TR

The BU4332FVE-TR offers a number of features: • Low operating power: The BU4332FVE-TR can operate with a supply voltage of 1.8 to 5.5V and consumes only 6.5 microamperes. This makes it ideal for battery-powered system applications. • Wide operating temperature range: The BU4332FVE-TR can operate from -40 to 125°C. This means it can be used in a wide range of environments. • High accuracy detection: The BU4332FVE-TR can detect reset signals with an accuracy of +/-2%. This makes it suitable for high-accuracy, precision applications. • Low I/O pin count: The BU4332FVE-TR has only five pins, making it ideal for space-constrained applications. • Fast response time: The BU4332FVE-TR can respond to reset signals in as little as 50ns, making it suitable for fast switching applications.

Working Principle of BU4332FVE-TR

The BU4332FVE-TR, as a precision reset IC, is designed to detect the reset signal and, upon detection, send a reset signal to the system. It consists of a threshold comparator, a comparator output driver, error/interrupt flag detection circuit, and an output latch.The output of the comparator is connected to the comparator output driver which converts the comparator output signal into a logic signal. This logic signal is the reset signal sent to the system when there is a power failure or a reset signal is triggered. The error/interrupt flag detection circuit detects the reset signal and initiates the reset signal process.The output latch holds the reset state until the reset signal is removed.

Conclusion

The BU4332FVE-TR is a precision reset IC from ROHM Semiconductor. It belongs to the Supervisors family of power management ICs and is mainly used in embedded systems and industrial control systems. The BU4332FVE-TR offers features like low power consumption, wide operating temperature range, high accuracy detection, low I/O pin count and fast response time. The BU4332FVE-TR works by detecting reset signals and, upon detection, sending a reset signal to the system.
