Beyond supplying power to each module, power management systems must be able to control when and how much current is allocated to each circuit, according to the need. Load switching and current drive are core functionalities of such systems. With regard to integrated circuits, PI5PD2560ZEE is a driver developed to provide coordinated load switching and current drive.

PI5PD2560ZEE is part of a comprehensive portfolio of power management integrated circuits (PMIC) offered by NXP Semiconductors. This PMIC is categorized as a Power Distribution Switch, Load Driver, and is designed to meet the most diffused portfolio of switch and load requirements. PI5PD2560ZEE can drive up to four loads, each one with its own independent control port. It is an ideal solution for applications such as battery-powered LED lighting and automated home appliances.

Features

PI5PD2560ZEE is a device specifically designed for low-power applications where a low number of switches and/or loads are required. The integrated four load switching DSMs support robust, low-power operation, while the PMOS load drivers have enhanced immunity against 25V transients or battery power-up. Other notable features include:

• Fast GPIO interface with no external crystal required
• High TS family performance
• A lifetime of up to 100 million triggers
• Operating temperature range of -40°C to +85°C
• Low voltage drop
• 4-port load switch supporting working voltage range of 1.8V to 6.1V

Application Field

PI5PD2560ZEE is an incredibly versatile part. This is because it includes four low-current PMOS MOSFETs, providing the regular load switch independent control and flexible current drive capabilities. As such, it is suitable for a wide variety of different scenarios.

Applications include those scenarios where both load switch control and current drive are required. This can be any situation where the equipment is powered off and on in different stages. This includes Battery-Powered LED lighting, Automated Home Appliances and Measurements and Verifications Systems.

Working Principle

PI5PD2560ZEE is a four-controlled, single-indication device. When the main power supply is on, the function of the device is to switch on and off the loads, and to drive their corresponding PMOS MOSFETs to host the peripheral circuits currents.

When the main power supply is off, PI5PD2560ZEE is enabled, and the DSMs gate turn-off signal is enabled, and the device goes into battery Drain mode. The PI5PD2560ZEE periodically switches the loads off for a short period of time, to allow the connected batteries to drain the necessary power. The PI5PD2560ZEE will return to its regular on/off load switch functionality once the main supply is back on.

When each load is turned on (or off) by a digital control signal, they draw current according to their own characteristics. PI5PD2560ZEE provides the necessary voltage and current drive, acting as a load switch and a load current driver.

Conclusion

PI5PD2560ZEE is a power distribution switch, load driver device capable of managing the various current requirements of different loads. This IC is capable of switching and driving up to four loads, and is suitable for applications such as battery-powered LED lighting and automated home appliances. It features a fast GPIO interface, enhanced immunity against 25V transients and high temperature performance.
