The BD46471G-TR is a voltage supervisor product in the PMIC (Power Management Integrated Circuit) Supervisors category. It is used to monitor, detect and respond to the voltage input from a power source, and is typically used by circuit designers making electrical equipment for powering multiple electronic devices for home, automotive, and industrial applications.

The BD46471G-TR has a stable threshold voltage level of 4.7V, which can be adjusted with a resistive voltage divider and externally. It uses a built-in circuit protection system with an overvoltage protection window of 4.3-4.7V, for applications with a 3.2-4.6V system voltage range. It also has an operating temperature range of -40°C - 85°C.

The BD46471G-TR is designed to be used in applications where a low voltage signal is required, such as a low voltage detector or signal line protector. It can be used to provide an alert or warning to the user in the event of a power disruption. This alert or warning can be an audible sound, a visual signal, or both.

The BD46471G-TR features an active low active RESET output pin, which can be used to trigger an interrupt in the target system. This pin is used to signal the host system when the voltage falls below the preset threshold level. The active low characteristic of this pin ensures that the target system knows that the signal from the BD46471G-TR is valid. The RESET output can be connected to an interrupt pin on the target system to ensure that the target system is aware of any power disruptions.

The BD46471G-TR also features a power on reset (POR) input pin, which can be used to reset the system when the power is restored after a power off situation. The POR input is an active low pin, and is used to reset the target system when the voltage goes above the preset threshold level. The POR input can also be used to reset the target system when the power is restored after a power failure.

The BD46471G-TR also features a failed power alarm output, which can be used to signal the user that the system has gone into low power mode. This output is an active high pin, and it is used to generate an alarm signal or a warning signal to the user when the voltage drops below the preset threshold level. The alarm output can be connected to an audible alarm or a visual signal to alert the user of the power disruption.

In addition, the BD46471G-TR also features an adjustable reset delay time, which can be used to customize the reset time for different applications. This feature is used to provide the host system with a longer period of time to respond to power disturbances. This allows the host system to adjust its own power rail and reset the target system in a safe manner, without having to wait for the voltage level to drop below the preset threshold.

The BD46471G-TR provides an efficient, reliable, and convenient way to monitor and protect power sources from voltage fluctuations. It is an essential tool for designing reliable applications with power monitoring and protection capabilities. It is ideal for automotive, industrial, and home electronics applications.
