Overview
The AP2151DM8G-13 is a single-channel, high-side power switch IC from Diodes Incorporated, designed for USB and hot-swap applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 0.5 A with a peak current capability of 0.6 A. The device features a maximum on-resistance of 115 mΩ and includes built-in protection against overcurrent, thermal overload, reverse current, and under-voltage lockout. It is housed in an MSOP-8 package with an exposed pad.
Feature Summary
- Integrated high-side P-channel power switch optimized for USB distribution
- Built-in fault protection including current limiting, thermal shutdown, and reverse current blocking
- Low on-resistance for efficient power delivery
- Single-channel configuration with enable control
Applications
- USB hub power distribution
- Hot-swap peripheral connections
- Portable device power management
- Battery-powered equipment load switching
Procurement Notes
Verify the exact suffix 'DM8G-13' matches the required MSOP-8EP package and RoHS compliance status. Confirm lead times as they may vary by distributor. Ensure ESD handling procedures are followed during assembly due to the sensitive gate structure. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component when a single-channel, current-limited high-side switch is required for 5V USB systems. It is suitable for applications needing integrated protection against short circuits and reverse polarity. Consider the MSOP-8EP package for thermal performance if space allows. Compare on-resistance and current limits against other AP2151 variants if higher current or different packaging is needed.
Part Context
This part belongs to the AP2151 series of power switches from Diodes Incorporated. The series offers various packages and current ratings for USB and general power distribution needs. The AP2151DM8G-13 specifically denotes the MSOP-8 package variant with standard commercial temperature range operation.
Replacement Considerations
Direct substitutes include other AP2151 variants such as AP2151MPG-13 (MSOP-8) or AP2151DMPG-13 (MSOP-8EP), provided pinouts and electrical characteristics match. Verify package dimensions and thermal pad requirements before substitution.
