BU4326F-TR

PMIC (Power Management Integrated Circuit) supervisors offer enhanced performance and monitoring features to extend system reliability and reduce design time and cost. In particular, the BU4326F-TR supervisor is a new-generation 3-terminal reset IC with a built-in delay circuit. It can monitor the power supply system to optimize system stability and reduce power consumption.

The BU4326F-TR can be used in a variety of applications and power systems, including microcontrollers, digital circuits, and analog circuits. It is designed to detect sudden power supply voltage drops and generate a reset signal to protect the system. It also provides a low-power reset signal for periodically supplying a reset signal to the device during power on. The reset signal is generated when the voltage reaches the detection threshold during power-up, power down, and power brownout, and maintains the reset state until the voltage returns to a safe voltage level.

The application field of the BU4326F-TR includes laptop computers, PDAs, digital cameras and other portable electronic devices, as well as automobile electronics systems. The BU4326F-TR can also be used for battery charging control, fault diagnosis and monitoring, LED backlight protection, boost protection and surge protection.

The BU4326F-TR is a 3-terminal reset IC with built-in delay circuit and two outputs, reset output (RESET) and toggle output (TOGGLE). The reset signal is output when the voltage reaches the detection threshold, with the time interval depending on the voltage drop rate. The toggle output is normally at low voltage, but switches to high voltage when the reset signal is input. The reset signal remains active as long as the voltage remains below the detection threshold.

The BU4326F-TR works in three phases: the operating phase, reset phase, and standby phase. During normal operation, the IC monitors the supply voltage and generates a reset signal when the voltage drops below the detection threshold. The reset signal is active for a fixed period. After the reset signal is generated, the IC enters the standby phase. During the standby phase, the IC monitors the supply voltage and is ready to generate a reset signal in the event of a voltage drop. During the reset phase, the IC monitors the supply voltage and generates a reset signal when the voltage drops below the detection threshold. After the reset signal is generated, the IC returns to the operating phase.

The BU4326F-TR has excellent voltage protection performance, with a low detection threshold and a high noise tolerance. It also has a wide operating temperature range of -40°C to +125°C and is resistant to noise and electromagnetic interference. The reset output is also available in both active high and active low configurations.

In summary, the BU4326F-TR supervisor is an excellent 3-terminal reset IC with built-in delay circuit, offering the enhanced performance and monitoring features needed to control and protect the power supply system and improve system stability. With its wide application field, excellent voltage protection performance, low detection threshold, and wide operating temperature range, the BU4326F-TR offers the reliability and protection that is essential for today’s powerful and complex electronics systems.
