AP2155SG-13 is a Power Management Integrated Circuit (PMIC) developed by Diodes Inc. It is a single-channel programmable Power Distribution Switch (PDS) and Load Driver (LD). This device is especially suitable for use in mobile applications, providing regulated power supply, as well as remote power control, from a single supply voltage.

Application Fields

AP2155SG-13 is widely used in various applications including SIMST, serial ATA, USB, radio frequency (RF), and modem interfaces. It is also used in battery-powered and automotive applications, such as cameras and display interfaces. The device can be used in audio and video interface applications, as well as energy meter, medical and industrial automation applications.

Working Principle

The AP2155SG-13 works by distributing power uniformly across all channels of a PDS. It provides a regulated power supply that can be adjusted to match the current demand. In addition, it also supports a wide range of load drivers, allowing users to adjust the output current for different loads. This is achieved by using the enable pins which control the flow of current between the supply voltage and the load.

The device can also be used to provide power sequencing for multiple serially connected devices. This is achieved by using the enable pins which are configured to set a unique time delay for each output channel.

The AP2155SG-13 also has overvoltage protection and undervoltage protection, which helps protect the device against extreme voltage changes.

Conclusion

AP2155SG-13 is a highly integrated PMIC with many applications. It is perfect for mobile applications, providing a regulated power supply and remote power control from a single supply voltage. In addition, it also supports a wide range of load drivers, overvoltage protection and undervoltage protection.
