Introduction

The BD9860MUV-E2 PMIC (Power Management Integrated Circuit) is a linear voltage regulator used in a wide variety of applications, such as consumer electronics, automotive electronics, computing and communication systems, and industrial electronics. It is a highly-integrated PMIC solution that offers low quiescent current and low noise performance, while providing flexibility in controlling power to various system components.

Features

The BD9860MUV-E2 PMIC offers several features to provide a comprehensive power management solution. First, it can regulate up to three output voltages from 3V to 24V. Depending on the configuration, the BD9860MUV-E2 also has an adjustable voltage-sharing capability, which can be used to reduce power dissipation during low power usage. Additionally, the BD9860MUV-E2 has a low quiescent current of only 33 mA, which allows for longer battery life in portable devices. Also, the BD9860MUV-E2 can support up to five system power domains, allowing it to be used in multi-power domain systems.

Application Fields

The BD9860MUV-E2 PMIC is suitable for a wide range of applications in consumer electronics, automotive electronics, computing and communication systems, and industrial electronics. Consumer electronics applications include portable audio/video products, power banks and charging systems, toys, and hand-held products. Automotive applications include in-vehicle entertainment systems, instrument clusters, and car infotainment systems. For computing and communication systems, the BD9860MUV-E2 can be used for handheld computing, IoT devices, and wireless communication devices. Industrial electronics applications include automatic controllers and programmable logic controllers.

Working Principle

The BD9860MUV-E2 PMIC is based on a linear voltage regulator topology, in which a low-voltage input signal is converted to a higher-voltage output signal by a finite amount. The PMIC utilizes the transistor-based operational amplifier (op-amp) circuit to adjust the output voltage. The op-amp is configured to act as a voltage follower, meaning that the output voltage is controlled by the input voltage and is regulated by an internal control circuit.The BD9860MUV-E2 also utilizes a feedback control loop to ensure that the output voltage is kept within the range specified by the user. The control loop regulates the op-amp output amplitude by comparing the output voltage signal with a reference signal. The reference voltage is either user-defined or can be set automatically. If the output signal deviates from the reference voltage, the control loop adjusts the output signal level in order to maintain a constant output voltage.Finally, the BD9860MUV-E2 also includes several other features to enable efficient operation, such as an enable pin for system power control and an enable signal for controlling the output current. Additionally, the control loop can be disabled to reduce quiescent current when the system is in standby mode.

Conclusion

The BD9860MUV-E2 PMIC provides a comprehensive solution for power management needs. It utilizes a linear voltage regulator topology and a feedback control loop to regulate voltages from 3V to 24V. This PMIC also offers an adjustable voltage-sharing capability, low quiescent current, and support for up to five system power domains. The BD9860MUV-E2 is suitable for a wide range of applications in consumer electronics, automotive electronics, computing, communication systems, and industrial electronics.
