AP2142AMPG-13

Overview

The AP2142AMPG-13 is a dual high-side power switch IC from Diodes Incorporated, designed for power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features two independent outputs with a maximum continuous output current of 500 mA per channel. The device specifies a maximum on-resistance of 105 mOhms and includes an internal current limit of 700 mA. Switching characteristics include a maximum turn-on time of 500 us and a maximum idle time of 300 us. It supports surface mount installation in an MSOP-8 EP package and functions reliably across an operating temperature range of -40 C to +85 C.

Feature Summary

• Dual high-side switching architecture for independent channel control
• Integrated overcurrent protection with defined current limiting threshold
• Low on-resistance design to minimize power loss during conduction

Applications

• USB port power switching and distribution
• Peripheral power management in consumer electronics
• Battery-powered device load switching

Procurement Notes

Verify the specific suffix PG-13 against official Diodes Incorporated documentation to confirm the exact tape and reel packaging configuration. Ensure the component meets RoHS compliance requirements as stated in the manufacturer's specifications. Cross-reference the datasheet revision date to confirm that all electrical parameters match the intended design constraints before finalizing procurement orders.

Selection Notes

Select this component when dual-channel high-side switching is required with a 500 mA per-channel current capacity. The low on-resistance value makes it suitable for applications where efficiency is critical. Verify that the system voltage remains within the 2.7 V to 5.5 V operational window. Consider the MSOP-8 EP package dimensions for PCB layout compatibility and thermal dissipation requirements relative to the expected load conditions.

Part Context

This part belongs to the AP2142 series of power switch ICs manufactured by Diodes Incorporated. The series focuses on compact solutions for distributing power to multiple loads in space-constrained environments. The AP2142AMPG-13 variant specifically denotes the dual-switch configuration with the associated packaging and marking codes defined by the manufacturer for traceability and quality control purposes.

Replacement Considerations

AP2142ASG-13 offers similar dual-switch functionality but utilizes an SOIC-8 package instead of MSOP-8 EP. Designers must evaluate pinout compatibility and physical footprint differences when substituting between these package variants. Other series members like AP2162 or AP2172 provide higher current ratings but may require different thermal management strategies.
