Diodes Incorporated AP2196MPG-13

Overview

AP2196MPG-13 from Diodes Incorporated is a dual-channel, active-high enable, high-side USB power switch with 2.1A current limiting, 90mΩ on-resistance (MSOP-8EP), and integrated short-circuit/thermal protection. It operates from 2.7V to 5.5V input, delivers controlled 0.6ms rise time, and supports hot-swap in USB 2.0-compliant host and self-powered hubs.

For engineers reviewing the AP2196MPG-13 datasheet, AP2196MPG-13 pinout, AP2196MPG-13 application, or AP2196MPG-13 equivalent, key selection criteria include active-high EN logic, dual independent FLG reporting with 7ms deglitch, reverse current blocking, UVLO at 1.9V, and thermal shutdown at 140°C with 25°C hysteresis.

Technical Context

The AP2196 integrates two independent high-side N-channel MOSFET drivers with dedicated current-sense FETs for accurate 2.1A over-current detection and thermal monitoring. Each channel features separate EN and open-drain FLG pins, enabling per-port fault isolation without shared control logic.

Its architecture implements UVLO (1.9V threshold), controlled turn-on via internal slew-rate limiting, and automatic thermal cycling (140°C trip / 115°C recovery) - all without external components. The MSOP-8EP package uses an exposed pad tied to GND for 60°C/W θ_JA, critical for sustained 1.5A continuous load operation.

Key Specifications

Pinout & Package

AP2196MPG-13 is housed in an MSOP-8EP (Exposed Pad) package. The exposed pad must be soldered to a PCB ground plane for thermal management and is not an electrical ground conduction path.

FAQ

What is the difference between AP2196MPG-13 and AP2186MPG-13?

The AP2196MPG-13 features active-high enable inputs (EN1/EN2), while the AP2186MPG-13 uses active-low enables. Both share identical current limit (2.1A), R_DS(ON) (90mΩ MSOP-8EP), FLG deglitch (7ms), and thermal shutdown (140°C). Pinout and package are identical; only logic polarity differs - requiring corresponding MCU GPIO configuration changes.

Can AP2196MPG-13 drive a 5V/1.5A load continuously in MSOP-8EP?

Yes - at 1.5A and 90mΩ R_DS(ON), power dissipation is 202mW. With θ_JA = 60°C/W and TA = 85°C, junction temperature reaches ~97°C, well below the 150°C absolute maximum. Use of the exposed pad with ≥3 thermal vias to a 1-in² GND plane ensures safe continuous operation.

Does AP2196MPG-13 require external components for basic USB 2.0 compliance?

No - the device integrates UVLO (1.9V), 7ms FLG deglitch, thermal shutdown, and reverse current blocking. Only mandatory external components are a 0.1µF ceramic capacitor from IN to GND and 68µF electrolytic capacitors on each OUT for stability - both specified in the USB 2.0 standard for port power delivery.

How does the FLG pin behave during a short-circuit event?

Upon detecting over-current, FLG asserts low after a nominal 7ms deglitch period and remains low until both over-current and over-temperature conditions clear. During thermal cycling (140°C trip → 115°C recovery), FLG stays low throughout the off-cycle and releases only after full recovery and stable current draw - enabling unambiguous fault latching in host firmware.
