Introduction:

A power management integrated circuit (PMIC) is a highly integrated silicon that offers designers a range of high voltage power capabilities to enable their designs. Specifically, the AS8650B-ZQFP-01 from Texas Instruments is a PMIC that provides designers a reliable and cost-effective supply voltage monitoring, LED current control and a wide range of general-purpose inputs/outputs. This PMIC typically runs on 2.5 V supply and provides a wide operating voltage range of 1.8V to 3.6V. This allows it to be integrated into many applications, especially for battery-powered product designs, making it an ideal solution for low-power applications. This article will discuss the application field and working principle of The AS8650B-ZQFP-01.

Application Field

The AS8650B-ZQFP-01 can be used in multiple applications. It can be used in LED lighting and video applications. It can be used in mobile phones ande-pens, where long battery life is highly desired. It is also suitable for industrial and automotive applications, as its wide operating voltage range allows it to cover a variety of power configurations. In addition, the AS8650B-ZQFP-01 is especially suitable for battery-powered product designs due to its low-power operation.

Working Principle

The AS8650B-ZQFP-01 PMIC uses an advanced energy-saving algorithm to keep the power supply low and provides a wide operating voltage range of 1.8V to 3.6V, which allows it to be used in a variety of power configurations. It consists of a pulse-width modulation (PWM) controlled step-down converter, two linear regulators and two input pins that can be connected to two external voltage sources as alternatives. The external voltage sources can be used for system operation and for support of the internal supply circuitry. The step-down converter can provide up to 1.5A output current and can be used to power digital logic, high current loads, or be used to charge batteries. The two linear regulators can provide up to 200mA output current each.

In addition, the AS8650B-ZQFP-01 provides a Low Voltage Detector (LVD) to detect the supply voltage and can be used to control the operating mode of the system. It also features a programmable supply voltage monitoring circuit with an adjustable threshold. The LVD monitors the system supply voltage and can be used to control the shutdown of the system in case of a voltage drop. In addition, the AS8650B-ZQFP-01 provides LED drivers and a wide range of general-purposed inputs/outputs, making it highly suitable for LED lighting and video applications.

Conclusion

The AS8650B-ZQFP-01 from Texas Instruments is a reliable and cost-effective PMIC that provides a wide range of power capabilities to enable product designs. It provides system designers with a reliable and cost-effective power solution for large-scale, battery-powered product designs. It offers supply voltage monitoring, LED current control and a wide range of general-purpose inputs/outputs. It is very suitable for mobile phones ande-pens that require long battery life.
