Overview
The AP2191SG-13 is a single-channel high-side power switch IC from Diodes Incorporated, designed for USB power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1.5 A with a maximum current limit of 2.1 A. The device features a typical on-resistance of 95 mΩ and a maximum of 115 mΩ. It includes thermal limiting, short-circuit protection, and undervoltage lockout. The component is housed in an SOP-8 surface-mount package and functions reliably across an operating temperature range of -40 °C to +85 °C.
Feature Summary
- Integrated high-side power switching optimized for USB 2.0 compliance
- Built-in thermal limiting and short-circuit protection mechanisms
- Undervoltage lockout functionality ensures stable operation during low voltage conditions
Applications
- USB port power distribution circuits
- Hot-swap applications requiring controlled rise times
- Battery-powered devices needing efficient power management
Procurement Notes
Verify the specific suffix 'SG-13' against the manufacturer's official datasheet DS31562 or equivalent documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the SOP-8 package. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as manufacturing updates may occur.
Selection Notes
Select this component when a single-channel solution with 1.5 A continuous current capability is required for USB interfaces. Consider the 95 mΩ typical on-resistance for efficiency calculations. Verify that the SOP-8 package fits the design constraints. Compare against the AP2191AMP variant if different packaging is needed, ensuring electrical parameters remain consistent with system requirements.
Part Context
This part belongs to the AP2191 series of power switches from Diodes Incorporated. The series focuses on providing robust protection features for portable electronics. The SG suffix typically denotes the SOP-8 package configuration. This family is engineered to meet industry standards for USB power delivery while minimizing external component count.
Replacement Considerations
The AP2191AMP-13 is a documented alternative within the same product family, offering identical electrical characteristics but potentially differing in package style or reel specifications. Verify pin-to-pin compatibility before substitution.
