AP2146MPG-13

Overview

The AP2146MPG-13 is a dual-channel high-side power switch IC manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA per channel with an 800 mA current limit. The device features a maximum on-resistance of 135 mOhms, a turn-on time of 50 us, and a turn-off time of 10 us. It is housed in an MSOP-8 EP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel high-side power switching capability for independent load control
• Integrated over-current protection limiting output to 800 mA
• Active-low interface enable control for logic compatibility

Applications

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

Procurement Notes

Verify the specific suffix 'MPG' against official Diodes Incorporated documentation to confirm the active-low enable configuration and MSOP-8 EP package type. Ensure design compliance with the specified 2.7 V to 5.5 V operating voltage range and thermal requirements for the intended application environment.

Selection Notes

Select this component when dual-channel switching with low on-resistance is required for 5V USB applications. Compare against the AP2146SG variant if active-high enable logic is preferred instead of active-low. Consider the MSOP-8 EP package for surface-mount assembly constraints and thermal dissipation needs.

Part Context

This part belongs to the AP2146 series of power distribution ICs from Diodes Incorporated. It provides dual-channel switching solutions designed for portable devices and USB interfaces. The series emphasizes low on-resistance and fast switching speeds to optimize power efficiency and signal integrity in compact electronic systems.

Replacement Considerations

AP2146SG-13 offers identical electrical specifications but utilizes active-high enable logic instead of active-low.
