AP2146SG-13

Overview

The AP2146SG-13 is a dual-channel high-side power switch IC manufactured by Diodes Incorporated, designed for USB interface applications. 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 a current limit of 800 mA. The device features a maximum on-resistance of 135 mOhms, ensuring efficient power distribution. Key timing parameters include a maximum turn-on time of 50 µs and a maximum turn-off time of 10 µs. It functions reliably across an operating temperature range from -40 °C to +85 °C and is available in surface-mount packaging.

Feature Summary

• Dual-channel configuration for independent load control
• Integrated current limiting to protect downstream circuits
• Low on-resistance for minimized power loss
• Fast switching speeds for responsive power management

Applications

• USB port power distribution
• Peripheral device power switching
• Battery-powered equipment load management

Procurement Notes

Verify the specific suffix 'SG-13' against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required thermal dissipation standards for the intended PCB layout. Cross-reference RoHS compliance status directly with the manufacturer's latest datasheet to meet regulatory requirements for your target market.

Selection Notes

Select this component when dual-channel high-side switching is required for low-voltage interfaces. Compare the 500 mA continuous output and 800 mA limit against load requirements. Evaluate the 135 mOhm on-resistance for thermal performance needs. Confirm that the SOP-8 package fits the design constraints and that the 2.7 V to 5.5 V input range matches the system power supply.

Part Context

This part belongs to the AP214x series of power switch ICs from Diodes Incorporated. These devices are engineered for portable electronics and USB peripherals requiring compact, efficient power distribution solutions. The series typically offers integrated protection features such as current limiting and thermal shutdown, making them suitable for modern low-power interface designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as the AP2142SG-13 or AP2156SG-13, which share similar dual-channel architectures. Verify that substitute parts maintain identical electrical characteristics, particularly the 500 mA output current and 135 mOhm on-resistance, to ensure circuit functionality remains unchanged.
