Overview
The AP2151AMP-13 is a single-channel high-side power switch optimized for USB and hot-swap applications. It operates within a supply voltage range of 2.7 V to 5.5 V. The device supports a continuous output current of 0.5 A with a peak capability of 0.6 A. It features an on-resistance of 115 mOhms maximum and includes built-in transient, overcurrent, thermal, and undervoltage protection. The component is housed in an MSOP-8-EP package and complies with USB 2.0 standards.
Feature Summary
- Integrated high-side power switching with controlled rise time and undervoltage lockout functionality
- Built-in protection mechanisms including current limiting, thermal shutdown, and short circuit protection
- Open-drain Flag output with 7ms deglitch capability to prevent false over-current reporting
Applications
- Universal Serial Bus (USB) power distribution
- Hot-swap applications requiring controlled power sequencing
- Peripheral driver circuits needing single-channel current limiting
Procurement Notes
Verify the specific suffix AMP-13 against official Diodes Incorporated documentation to confirm the MSOP-8-EP package configuration. Ensure compatibility with required enable input polarity options. Cross-reference datasheet revision DS31562 Rev. 10 for accurate electrical characteristics and pin assignments prior to integration.
Selection Notes
Select this component for designs requiring a single-channel USB-compliant power switch with integrated protection. Consider the MSOP-8-EP package for space-constrained layouts. Verify that the 0.5 A continuous current rating meets load requirements and that the 2.7 V minimum operating voltage aligns with system power rails.
Part Context
The AP2151AMP-13 belongs to the AP2151 series of power switch ICs manufactured by Diodes Incorporated. This family is designed for high-side switching applications, offering robust protection features suitable for sensitive peripheral connections. The part integrates control logic and power MOSFETs into a compact surface-mount package.
Replacement Considerations
AP2151MPG-13: Single-channel variant in MSOP-8-EP package. AP2151AFM-7: Single-channel variant in UDFN-6 package. AP2151AW-7: Single-channel variant in SOT-25-5 package.
