Diodes Incorporated AP2182MPG-13

Overview

AP2182MPG-13 from Diodes Incorporated is a dual-channel, active-low-enable, high-side USB power switch with 2.1A current limiting, 115mΩ on-resistance (MSOP-8EP), and integrated short-circuit/thermal protection. It operates from 2.7V–5.5V input and delivers controlled 0.6ms rise time for hot-swap USB port management in host-powered hubs and docking stations.

For engineers reviewing the AP2182MPG-13 datasheet, AP2182MPG-13 pinout, AP2182MPG-13 application, or AP2182MPG-13 equivalent, key selection criteria include enable polarity (active-low), dual independent fault reporting via open-drain FLG pins with 7ms deglitch, reverse current blocking, and thermal shutdown at +140°C with 25°C hysteresis.

Technical Context

The AP2182MPG-13 integrates two independent high-side MOSFETs with matched current-limit sensing and separate EN/FLG pins per channel. Its UVLO threshold is fixed at 1.9V (typ), and it employs internal sense-FET current monitoring-eliminating external sense resistors while maintaining low R_DS(ON).

Each channel features independent deglitched open-drain FLG outputs that assert low only after sustained over-current or over-temperature events exceed 7ms blanking time. Thermal shutdown activates at +140°C and recovers after cooling to +115°C, enabling safe auto-retry behavior during persistent faults.

Key Specifications

Pinout & Package

AP2182MPG-13 is housed in an MSOP-8EP (Exposed Pad) package. The exposed pad must be soldered to PCB ground plane for thermal performance but is not an electrical ground conduction path.

FAQ

What is the maximum continuous load current supported by AP2182MPG-13?

The AP2182MPG-13 supports 1.5A maximum continuous load current per channel, as specified in the Recommended Operating Conditions table. This rating accounts for thermal derating across the full -40°C to +85°C ambient range and ensures reliable operation within the MSOP-8EP package's 60°C/W θ_JA thermal resistance.

Does AP2182MPG-13 require external components for over-current protection?

No external components are required for basic over-current protection. The device integrates current-sense FETs, deglitched FLG outputs, and thermal shutdown. Only external pull-up resistors on FLG1/FLG2 are needed for proper open-drain operation; bypass capacitors (0.01–0.1µF ceramic) are recommended but not protection-critical.

Can AP2182MPG-13 be used in 3.3V-only systems?

Yes. The AP2182MPG-13 operates across 2.7V–5.5V input, making it fully compatible with 3.3V systems. Its EN input logic thresholds (V_IL ≤ 0.8V, V_IH ≥ 2V) ensure reliable active-low control from standard 3.3V GPIOs, and its 115mΩ R_DS(ON) remains effective at 3.3V input.

How does the 7ms FLG deglitch function interact with short-circuit events?

The 7ms deglitch timer requires sustained over-current or over-temperature conditions beyond 4ms (min) before asserting FLG low. During brief inrush or transient shorts (<4ms), FLG remains inactive-preventing false interrupts. Once asserted, FLG stays low until both fault conditions clear, ensuring reliable host-level fault detection without spurious resets.
