The AZ431BZ-BTRE1 is a Voltage Reference device that belongs to the family of PMIC (Power Management Integrated Circuits). It is a three-terminal adjustable shunt regulator with programmable voltage, output voltage and current range. The AZ431BZ-BTRE1 has an input voltage range of 0.7V to 10V and an output voltage range of 0.2 to 10V. The device is suitable for applications such as low dropout (LDO) regulators, linear regulators and current references. It is ideal for controlling a wide range of power requirements and can be used in a variety of circuits.

The main application field of the AZ431BZ-BTRE1 is in power supply voltage regulation and current limiting. It is commonly used in automotive applications to provide drive current and protection for battery-related components. It is also used in industrial applications for controlling current and voltage of motors, heaters and fans. The device also finds its application in battery charging circuits and pulsed power systems.

The operating principle of the AZ431BZ-BTRE1 is based on the voltage controlled response of a shunt regulator. The output voltage is determined by the voltage drop of the control element. The output voltage is independent of temperature and load conditions typical of shunt regulator circuits. A comparison of the output voltage to a reference voltage is made, and depending on the comparison, either the output current is increased or decreased. This ensures that the output voltage is maintained at the desired level.

The AZ431BZ-BTRE1 also provides programmable precision current limit protection and adjustable current limit. It is able to detect short-circuit and over-temperature conditions which it reacts by limiting the output current or by shutting down the device completely. It has an output stage capable of passing up to 100mA of load current and can operate at input voltages up to 10V.

The AZ431BZ-BTRE1 is an efficient and robust solution for voltage regulation and current limit protection in a wide range of applications. It is a helpful tool for circuit designers in order to provide an adjustable and stable output voltage with zero-drift operation, robust current limit protection, low quiescent current, and reliable output current. The device is suitable for a wide range of power requirements and can be used in automotive, industrial and consumer applications where precision voltage regulation and current control is required.
