The BD46342G-TR is a PMIC - Supervisor that is used in microcontroller systems. It is comprised of two main components: a supervisor and a supervisor transistor that are integrated together in the same package. The supervisor monitors the power supply and system power supplies, while the supervisor transistor provides an input circuit that can be used for external system inputs, such as for an Analog-to-Digital Converter (ADC) or Digital-to-Analog Converter (DAC).

The BD46342G-TR features a wide supply voltage range from 3.3V to 20V. Its output current is up to 2A, and its operating temperature range is -40°C to 85°C. It is used to provide power to microcontroller or microprocessor circuits that require a high level of precision and accuracy. Its ability to provide accurate and reliable power management makes it suitable for use in many fields, including automotive, industrial, instrumentation and mobile applications.

The BD46342G-TR’s primary application field is microcontroller systems. The supervisor monitors the power supply and system power supplies, and the supervisor transistor provides an input circuit that can be used for external system inputs, such as for an Analog-to-Digital Converter (ADC) or Digital-to-Analog Converter (DAC). The supervisor is designed to detect any faults in the power supply, such as overvoltage, undervoltage, brownout or startup events, and will activate the transistor to re-supply power to the microcontroller. The transistor also allows for manual power on/off control by connecting it to the internal power switch.

The BD46342G-TR’s working principle relies on two integrated circuits (ICs): the supervisor and the supervisor transistor. The supervisor is a voltage monitor that constantly monitors the power supply and system power supplies, and will detect any power supply faults. In the event of a fault, such as overvoltage, undervoltage, brownout or startup events, the supervisor will send a signal to the supervisor transistor, instructing it to re-supply power to the microcontroller. The transistor will open a connection between the power supply and the microcontroller and will supply power until the fault is cleared.

The BD46342G-TR is typically used in automotive, industrial and instrumentation applications. It is designed to provide precise power management for microcontroller or microprocessor circuits and can operate in temperatures ranging from -40°C to 85°C. Its wide range of features makes it suitable for a variety of applications, and its ability to provide precise and reliable power management makes it a popular choice in many industries.
