The BU4320F-TR is a high efficiency voltage supervisor product released by ROHM Corporation. It has wide application fields such as computers, cellular phones, digital cameras, fax machines, measuring instrumentation and other consumer electronic related fields. The BU4320F-TR is a voltage supervisor designed to detect out-of-tolerance voltage, and provide automatic reset or warning output. It also provides over-voltage protection, brown out protection, and other functions.

The BU4320F-TR is an enhanced programmable voltage supervisor. It contains a power reset/reset controller IC. This IC features features designers with a wide range of voltage supervision options, including both open- and closed-loop voltage supervision, with comprehensive programmable options such as hysteresis and delay times. It has a wide-range of input voltages, and a variety of fixed and programmable watchdog output options. It is also capable of handling the vast majority of voltage supervision tasks encountered in consumer electronic applications and machines.

The BU4320F-TR features two main operating modes: open loop and closed loop. The deviceis capable of operating in either mode depending on the configuration of the hardware. The open loop mode is used when the external environment has predictable and fixed voltage levels, while the closed loop mode is used when the external environment has unpredictable or variable voltage levels.

In the open loop mode, the BU4320F-TR monitors the voltage level on the input voltage pin. Any signal outside the pre-set voltage range triggers a reset signal. This signal can be either active-low or active-high depending on the configuration of the circuit.

In the closed loop mode, the BU4320F-TR uses an internal reference voltage to monitor the input voltage. Any signal outside the pre-set voltage range will results in an adjustment signal, which is used to control the output voltage of an external regulator.

The BU4320F-TR is used in a variety of applications, such as computer motherboards, automotive systems, portable device power, solar inverters, industrial systems, and other consumer electronic related fields. The BU4320F-TR has been designed for use in high voltage applications up to 35V, making it suitable for a wide range of applications.

The BU4320F-TR is a highly integrated voltage supervisor, designed to provide designers with a wide range of programmable options including a comprehensive programmable reset, push/pull watchdog reset, brown out protection, and other functions. It is also capable of handling a wide range of voltage supervision tasks, making it an ideal choice for consumer electronics. The BU4320F-TR is a must-have product for all consumer electronics related applications, providing powerful voltage supervision and protection.
