BD46385G-TR is a product in the PMIC - Supervisors family that has many applications and uses. This device is widely used in consumer electronics, automotive, and industrial systems to provide power and reset functions. It has multiple reset outputs, adjustable monitoring thresholds, and a low-power consumption feature.

The device is a 4-channel low drop-out (LDO) voltage supervisor with an adjustable reset threshold. The reset threshold can be adjusted from 0.9 to 5V by adding resistors. It has two independent reset output pins that can provide both active-low level and active-high level signals. The device is powered by a 2.6 to 5V power supply voltage, with a wide operating temperature range from -40 to 125°C.

The BD46385G-TR is designed to detect an undervoltage or an overvoltage condition on a power supply line and produce reset or monitoring signals accordingly. It can monitor the power supply voltage on a system, and if the voltage drops below or rises above the adjusted threshold, the device can issue a reset signal to reset the device or alert the system. The reset output levels are adjustable with an external voltage, and the reset delay time can also be adjusted.

The device has an integrated power-on reset circuit that provides a reset signal when the power is applied or removed. The power-on reset can be configured to be either active-high or active-low, depending on the configuration. The VDD pin has an adjustable undervoltage threshold that ensures that the voltage does not go below the set value before any action is taken. This pin can also be used as an active-low reset output.

As for the working principle, the BD46385G-TR monitors the voltage at the B1 pin and compares it to the user-programmed threshold. When the voltage at the B1 pin falls below or rises above the threshold, the device will output a reset signal. This reset signal can be configured to be either active-high or active-low, depending on the configuration.

The device also has a watchdog timer, which is used to detect faults in the system. If the voltage on the B1 pin does not toggle within the programmable time period, the device will issue a reset signal. This reset signal will reset the system or alert the controller if a fault occurs.

The BD46385G-TR is an ideal device for systems with multiple voltages, as it can detect when the voltages go outside the thresholds and issue a reset signal. This device is also useful for monitoring power supplies in systems that may be subject to large voltage fluctuations. As it has an adjustable reset threshold, it can be tailored to suit the particular applications.

Overall, the BD46385G-TR is a versatile and powerful device that can be used in a variety of applications. It is easy to use and configure, and provides excellent performance and reliability in power and reset functions. With its multiple reset outputs, adjustable thresholds, low power consumption, and wide operating temperature range, it is the perfect choice for applications that require monitoring and reset functions in a power-supply–based system.
