Diodes Incorporated AP2182AFGEG-7

Overview

AP2182AFGEG-7 from Diodes Incorporated is a dual-channel, active-low enable, current-limited high-side power switch in U-DFN3030-8 (Type E) package, designed for USB 2.0 and hot-swap applications. It delivers 1.5A continuous per channel, features 85mΩ typical R_DS(ON), 2µs short-circuit response, integrated output discharge, and 7ms deglitched FLG reporting - enabling robust protection in systems with heavy capacitive loads such as USB hubs and docking stations.

For engineers reviewing the AP2182AFGEG-7 datasheet, AP2182AFGEG-7 pinout, AP2182AFGEG-7 application, or AP2182AFGEG-7 equivalent, key selection criteria include active-low EN polarity, dual-channel independent control, 2.7V–5.5V input range, reverse-current blocking, and thermal/overcurrent fault flag timing behavior under real-world load transients.

Technical Context

The AP2182AFGEG-7 implements two independent P-channel MOSFET high-side switches with matched current-limit thresholds (2.0A typ per channel) and separate open-drain FLG outputs. Each channel includes dedicated current-sense circuitry, UVLO (2.0V threshold), and thermal shutdown at 140°C with 25°C hysteresis.

Its discharge function activates on disable via internal N-MOS path (R_DIS = 100Ω), ensuring controlled V_OUT decay without external components. The 0.6ms typical rise time and 7ms FLG blanking are hardware-deglitched - no external RC filtering required for reliable overcurrent reporting in noisy hot-plug environments.

FAQ

What is the maximum continuous load current per channel for AP2182AFGEG-7?

The AP2182AFGEG-7 is rated for 1.5A continuous output current per channel under recommended operating conditions (TA = –40°C to +85°C, VIN = 2.7V–5.5V). This rating accounts for thermal derating in the U-DFN3030-8 package; peak current limit is 2.0A typical, but sustained operation above 1.5A risks thermal shutdown due to junction temperature rise.

Does AP2182AFGEG-7 require external components for overcurrent fault reporting?

No. The AP2182AFGEG-7 integrates a 7ms hardware deglitch timer on each FLG output, eliminating false triggers from capacitive inrush currents without external RC networks. The open-drain FLG pins drive standard logic-level inputs directly; only a pull-up resistor (typically 10kΩ to VIN) is needed for proper logic-level translation.

How does the output discharge function operate, and when is it active?

The discharge function activates automatically when either EN1 or EN2 is de-asserted (driven high), or during power-up/power-down when VIN falls below UVLO (≈2.0V). It engages an internal 100Ω N-MOS path between OUTx and GND, discharging external load capacitors within milliseconds - preventing floating outputs and ensuring safe hot-removal of USB peripherals.

Can AP2182AFGEG-7 be used in automotive applications?

The AP2182AFGEG-7 is not AEC-Q100 qualified and is specified for industrial temperature range (–40°C to +85°C), not automotive grade (–40°C to +125°C). Diodes Incorporated explicitly states that automotive-qualified versions require separate change control, PPAP capability, and IATF 16949 manufacturing - this part is intended for commercial/industrial USB and hot-swap systems only.
