MC33AR6000BGWS Application Field and Working Principle
Introduction
MC33AR6000BGWS is a type of Voltage Regulator (VR), which falls into the category of Special Purpose Power Management IC (PMIC). This device provides constant voltage, current, and adjustable power source for industrial, automotive and other electronic applications to ensure desired reliability, accuracy, and efficiency. It is able to regulate the input voltage from a wide range from 7V to 14V and output voltage from 1V to 13V with +/-1% accuracy. It is also able to deliver up to 10A of peak current and 2A of continuous output current.Being able to operate over a wide temperature range, the device is suitable to work in extreme environmental conditions. It also has a high power efficiency with low power dissipation, which makes it ideal for use in battery powered solutions. The component possesses multiple protection features, like over voltage, over current, over temperature, and short-circuit protection, to ensure system safety.
Application Field
The MC33AR6000BGWS is best suited for automotive, telecommunication, avionic, and industrial applications. It is specifically designed for those applications in which an adjustable, highly accurate, low voltage source is required and should provide high reliability without causing a burden for the system.In automotive applications, MC33AR6000BGWS is compatible with those batteries with varying voltage characteristics, like the lithium ion battery packs, and provides a constant voltage output to some components in the vehicle, like anti-lock brake system (ABS) and airbag control module. The component can also be used to provide power stabilization for other applications such as air-conditioning systems.In telecommunication applications, the MC33AR6000BGWS can be used to provide regulated output for auxiliary circuits, like line interface and cable notch filter circuits, in multiple systems including low and medium power transmission applications. It is also suitable for powering up other subsystems, like buffered switches and digital signal processor.The component finds one of its most suitable applications in avionics. Because of its stability and high accuracy, it can be used to keep the various communication systems, navigation devices, and even the airspeed sensors, of a flying aircraft, in working order for reliable activity. In industrial applications, MC33AR6000BGWS can be used to provide regulated power supply to systems operating in harsh environmental conditions. It can also be used to provide power stabilization to sensitive measuring and control equipment, like flow meters and controllers.
Working Principle
The MC33AR6000BGWS is a pulse width modulated (PWM) voltage regulator. In the device, the input voltage is rectified by the diode bridge, and then filtered by Cin capacitor. The filtered voltage is sensed by the input voltage control circuitry connected to the VIN pin. This control circuitry keeps monitoring the voltage and if the voltage drops below a certain threshold, the circuit triggers the PWM logic to reduce the conduction time of the off time of the power switch to increase the output voltage. This in turn reduces the current at the output, thus regulating the output voltage.The MC33AR6000BGWS also has an internal voltage reference (Vref) which works in sync with the current feedback loop. When the Vref is positive and the load current is more than what is expected, the PWM logic reduces the conduction time of the power switch, thus reducing the output voltage. On the other hand, if the load current is less than what is required, the control circuitry increases the duty cycle of the power switch, thus increasing the output voltage.In the MC33AR6000BGWS, the output voltage is fine-tuned with the help of an integrated variable reference voltage. This voltage provides the same voltage to the Vref pin and to the external resistor divider network. This variable reference voltage is also used to prevent over temperature and over current condition by either reducing the current or reducing the duty cycle.
