Overview
The AP2172ASG-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 A per channel with a maximum on-resistance of 110 mOhms. The device features a 1.4 A current limit, a maximum turn-on time of 500 us, and a maximum turn-off time of 300 us. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual-channel high-side switching capability for independent load control
- Integrated over-current protection with fixed current limiting
- Low on-resistance design for efficient power delivery
Applications
- USB hub power distribution circuits
- Portable electronic device power management
- Peripheral port protection and switching
Procurement Notes
Verify the specific suffix ASG-13 against the manufacturer's official datasheet to confirm the SOIC-8 package and electrical parameters. Ensure compatibility with the target PCB footprint and thermal requirements. Cross-reference the RoHS status and lead-free specifications with current production notices. Confirm that the ordering information matches the exact part number required for the design implementation.
Selection Notes
Select this component when dual-channel high-side switching is required for 5V USB applications. The 1A output rating and low on-resistance make it suitable for powering standard USB peripherals. Consider the SOIC-8 package for standard surface-mount assembly processes. Verify that the 2.7V to 5.5V input range aligns with the system's power supply architecture and load requirements.
Part Context
This part belongs to the AP2172 series of USB power switches by Diodes Incorporated. It provides dual-channel functionality compared to single-channel variants like the AP2171. The series is designed for portable electronics and USB hubs, offering protection and power distribution in a compact form factor. It complements other Diodes Incorporated PMIC solutions for comprehensive power management systems.
Replacement Considerations
AP2172AMPG-13 offers similar dual-switch functionality but uses an MSOP-8 EP package with a slightly lower on-resistance of 105 mOhms. Designers must verify pinout compatibility and thermal pad requirements when substituting between SOIC-8 and MSOP-8 packages.
