AP2182SG-13

Overview

The AP2182SG-13 is a dual-channel high-side power switch IC from Diodes Incorporated, designed for USB power distribution. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1.5 A per channel with a current limit of 2.1 A. The device features a maximum on-resistance of 135 mOhms and is housed in an SOP-8 surface-mount package. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel high-side switching architecture for independent load control
• Integrated overcurrent protection with defined current limiting thresholds
• Low on-resistance design to minimize power dissipation and heat generation

Applications

• USB hub power distribution circuits
• Peripheral device power gating
• Portable electronics load switching

Procurement Notes

Verify the specific suffix 'SG-13' against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure that the SOP-8 package variant matches the required PCB footprint and thermal management strategy for the target application environment.

Selection Notes

Select this component when dual-channel high-side switching is required within a 2.7V to 5.5V system. Consider the 1.5A continuous output capability and 2.1A current limit for load requirements. Evaluate the SOP-8 package constraints against available board space and thermal dissipation needs compared to alternative packages like MSOP.

Part Context

This part belongs to the AP2182 series of power switch ICs. It is categorized under Power Distribution switches within the broader PMIC portfolio. The device complements single-channel variants by providing two isolated outputs in a compact form factor suitable for multi-port interfaces.

Replacement Considerations

AP2196SG-13 offers similar dual-channel performance with comparable voltage and current ratings but may differ in timing characteristics or on-resistance values.
