Overview
The AP2145SG-13 is a high-side dual-channel 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 500 mA with an 800 mA current limit. The device features a maximum on-resistance of 160 mOhms and includes thermal limiting and short-circuit protection. It utilizes active-low enable logic and offers controlled rise times to meet USB specifications. Packaged in an SOP-8 format, it functions reliably across temperatures from -40°C to +85°C.
Feature Summary
- Dual-channel high-side switching architecture optimized for USB applications
- Integrated current and thermal limiting with short-circuit protection
- Active-low enable logic for flexible control interface
Applications
- USB hub power distribution
- Hot-swap peripheral connections
- Portable electronic device power management
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate electrical parameters such as on-resistance and operating temperature ranges before finalizing procurement orders.
Selection Notes
Select this component when dual-channel high-side switching is required for low-voltage systems. It is suitable for designs needing integrated over-current protection without external sensing resistors. Consider the SOP-8 package constraints and active-low enable requirement during schematic capture. Verify that the 500 mA continuous current rating aligns with the load requirements of the connected peripherals.
Part Context
This part belongs to the AP214x series of power switches from Diodes Incorporated. These devices are engineered for portable electronics and USB interfaces, offering compact solutions for power routing. The series typically includes variants with different channel counts and current ratings, all sharing common protection features like thermal shutdown and under-voltage lockout.
Replacement Considerations
AP2145MPG-13: Offers identical electrical performance but utilizes an MSOP-8EP package instead of SOP-8. Verify footprint compatibility if substituting directly on existing PCB layouts.
