AS3711-BQFP-00 is a power management IC (PMIC) device manufactured by Austria Microsystems. It is classified as a Specialized PMIC, and is designed to provide a versatile, low-power system-level solution for embedded applications. This device integrates an extensive set of features for load power management, including a wide range of adjustable lineart and non-linear regulators along with an adjustable pulse-width modulator (PWM) for digital power conversion. The AS3711-BQFP-00 is a highly integrated PMIC and offers a designer the flexibility to achieve low power at system level, while enabling a range of applications from single-cell to multi-cell systems.

The primary application field for the AS3711-BQFP-00 is the consumer electronics market, specifically those applications with a large display or backlighting that require a powerful, efficient power source. Such products include smartphones, tablets, notebooks, and consumer audio/video products.

The AS3711-BQFP-00 is designed to solve the power supply related problems faced by embedded applications. The device integrates a DC-to-DC step-down converter, which allows power to be regulated in a wide range of near-zero power and high-performance solutions. The PMIC also features an adjustable low-noise, high-efficiency LDO for circuits requiring low output voltages of 0.8V to 3.3V. The AS3711-BQFP-00 also includes adjustable linear and non-linear regulators that can be used in a wide range of applications.

The device also integrates a pulse-width modulation (PWM) facility that allows the user to define and adjust the pulse width of the output signal. This PWM feature significantly improves the power efficiency compared to traditional solutions, allowing for a more efficient power supply for embedded applications. In addition, the device integrates a tamper protection circuit to protect against malicious power supply manipulation.

The AS3711-BQFP-00 also features integrated temperature and overvoltage protection circuits that detect if the temperature or voltage of the device exceeds a predetermined level and then shut off the device in order to prevent damage to the device or other components. These features ensure that the device operates in a safe and secure manner, reducing the risk of any electrical malfunction.

The AS3711-BQFP-00 is also capable of being configured in a way so as to support a variety of power modes, such as sleep, standby, and active. This allows the user to conserve power when not in use, whilst also allowing for a quick switch when necessary. Also, several dynamic current limits can be programmed to allow for flexibility in the current usage of the device.

The working principle of the AS3711-BQFP-00 lies in its ability to provide a wide range of output voltages, as well as its wide range of input/output protection and control features. The device utilizes an efficient DC-to-DC step-down converter and an adjustable low-noise linear regulator, allowing for a range of regulated voltages depending on the voltage range the device is presented with. In addition, the adjustable linear regulator is used to ensure that if the output voltage of the device is over- or under-volted, the device will shut off in order to prevent any damage to the device or surrounding components.

The device also features an adjustable pulse-width modulator (PWM), which is used to vary the pulse width of the output signal. With the use of the PWM, the device can be fine-tuned to ensure the most power efficient solutions for embedded applications. Furthermore, the PWM also enables designers to implement a range of digital power management schemes, such as those that employ special non-linear controllers, digital inputs, and load-current detection.
