Power management integrated circuits (PMICs) are utilized in a variety of electronics applications to organize and manage the overall power consumption of a system. PMICs are capable of regulating the voltage and current delivered from a source while also overseeing thermal protection and power management. Within PMICs, power distribution switches, load drivers and logic controllers are used to manage the various aspects of a system’s energy requirements. One such device, the MP5016HGQH-Z, is one of the many available PMICs designed for today’s modern everyday products.

MP5016HGQH-Z Application Field

The MP5016HGQH-Z is a 2.5V to 3.6V input, 4-channel low-side power distribution switch with power sequencing logic and I2C compatible interface from Macronix. The device is targeted at rapidly developing mobile phone, tablet, wearable, and IoT applications. The MP5016HGQH-Z simplifies the power sequencing on multiple rails for mixed-signal systems by interacting with and controlling external power switches and variable voltage regulators. The device integrates a 4-channel low-side power distribution switch, two differential I2C compatible inputs and outputs, an asynchronous reset output and a unique power sequencing logic.

The device includes over voltage and over current protection circuitry, open load detection and reverse battery protection features. The MP5016HGQH-Z also features a protection mode that reduces the current of the channel selected down to 0.15N A, when an Over Current event occurs, without affecting the continuity of the signal and protecting other channels. The device can be programmed through the I2C interface and its configuration settings are stored in a non-volatile memory array.

MP5016HGQH-Z Working Principle

The primary principle of the MP5016HGQH-Z is its ability to control the sequencing of power on multiple rails. The onboard power sequencing logic simplifies the task of driving numerous isolated rails for a multi-rail system with as few as one I2C command. The device operates in a closed-loop control mode from its absolute input voltage to its main voltage output. This makes power sequencing simpler and more efficient in comparison to the traditional method.

In addition to its primary purpose, the device can also be utilized to optimize power management in a variety of other applications. It can be used to control numerous power rails simultaneously; to monitor the status of each rail; provide logic feedback from devices and modules; issue a warning before a potential over-current or over-voltage situation; and provide a shut-down voltage level for powering down the system.

To simplify configuration and operation, the MP5016HGQH-Z provides several I2C commands to create a register of output voltages, power-on/off timing, and power-on seqences. Furthermore, the MP5016HGQH-Z incorporates various protection features, such as over current and over voltage protections, open load detection, and reverse battery protection.

Conclusion

The MP5016HGQH-Z is a feature rich and highly configurable low-side power distribution switch with integrated power sequencing logic. The device is used to control the sequencing of power on multiple rails in a variety of mobile, tablet, and IoT applications. With its integrated protection features and I2C commands, the MP5016HGQH-Z simplifies the task of creating power rails and managing power distributed in electrical systems.
