AP2152AMPG-13

Overview

The AP2152AMPG-13 is a dual-channel current-limited high-side power switch from Diodes Incorporated, designed for USB and hot-swap applications. It operates within a supply voltage range of 2.7V to 5.5V and delivers an output current of 0.5A per channel with a typical on-resistance of 85mΩ. The device features a fast short-circuit response time of 2µs and includes built-in soft-start with a typical rise time of 0.6ms. It provides reverse current blocking, thermal protection, and fault reporting capabilities. Packaged in MSOP-8EP, it supports active-high enable inputs and functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture with integrated output discharge and reverse current blocking
• Fast short-circuit response time of 2µs with accurate 0.7A current limiting
• Built-in soft-start mechanism with typical 0.6ms rise time
• Integrated fault report (FLG) pin with blanking time

Applications

• Universal Serial Bus (USB) port protection
• Hot-swap circuit applications
• LCD TVs and monitors
• Set-top boxes and residential gateways
• Laptops, desktops, servers, printers, docking stations, and hubs

Procurement Notes

Verify the specific suffix 'MPG' corresponds to the MSOP-8EP package variant when sourcing. Confirm RoHS compliance and lead-free status through official manufacturer documentation. Ensure the active-high enable logic matches system requirements, as this variant differs from the active-low AP2142A. Cross-reference the datasheet revision to confirm thermal and electrical specifications align with design constraints.

Selection Notes

Select the AP2152AMPG-13 for designs requiring dual-channel protection with active-high control signals. Compare against the AP2142A family if active-low enable is preferred. Consider the 85mΩ on-resistance for power loss calculations in low-voltage USB applications. Evaluate the 2µs response time against load transient requirements. Verify that the MSOP-8EP exposed pad package meets thermal dissipation needs for the target environment.

Part Context

This component belongs to the AP2142A/AP2152A family of dual-channel current-limited power switches optimized for USB standards. The AP2152AMPG-13 specifically denotes the active-high enable version housed in an MSOP-8EP package. It complements single-channel variants like the AP2151AMP-13 by providing two independent protected outputs within a compact surface-mount footprint suitable for space-constrained consumer electronics.

Replacement Considerations

AP2142AMPG-13: Functional equivalent with active-low enable input instead of active-high.

FAQ

What is the difference between AP2152A and AP2142A?

The primary difference is the enable input polarity; AP2152A uses an active-high enable, while AP2142A uses an active-low enable.

Does the AP2152AMPG-13 support reverse current blocking?

Yes, the device features built-in reverse current blocking capability.
