Overview
The AP2166SG-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 1 A per channel with a 1.5 A current limit. The device features a maximum on-resistance of 135 mOhms, ensuring efficient power distribution. It includes interface enable functionality for active-low control. The component is designed for surface mount installation in SOP-8 packages and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel high-side power switching capability
- Active-low interface enable control logic
- Integrated overcurrent protection with defined limits
Applications
- USB port power distribution and management
- Peripheral circuit power sequencing
- Embedded system load switching
Procurement Notes
Verify the specific suffix 'SG' against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required SOP-8 configuration. Cross-reference the datasheet for moisture sensitivity levels and recommended soldering profiles prior to procurement to guarantee component integrity during assembly.
Selection Notes
Select this component when dual independent high-side switching with low on-resistance is required for 3.3V or 5V systems. The active-low enable feature simplifies control logic integration. Consider the SOP-8 footprint and thermal performance characteristics relative to the application's space constraints and ambient operating conditions.
Part Context
This part belongs to the AP2166 series of USB power switches from Diodes Incorporated. The series focuses on compact, high-efficiency power distribution solutions for portable electronics. The SG suffix typically denotes the specific package variant and packaging method, distinguishing it from other pinout or thermal options within the same functional family.
Replacement Considerations
Consult official manufacturer substitution guides for verified alternatives. Generic cross-references may not match the specific interface enable logic or exact on-resistance values.
