Diodes Incorporated AP2186MPG-13

Overview

AP2186MPG-13 from Diodes Incorporated is a dual-channel, active-low enable, high-side USB power switch with integrated current limiting (2.1A typ), 90mΩ R_DS(ON) (MSOP-8EP), and 7ms deglitched fault reporting. It operates from 2.7V–5.5V input, delivers up to 1.5A continuous per channel, and is qualified for USB 2.0 hot-swap applications in consumer electronics and computing peripherals.

For engineers reviewing the AP2186MPG-13 datasheet, AP2186MPG-13 pinout, AP2186MPG-13 application, or AP2186MPG-13 equivalent, this device supports dual-port USB power management with reverse-current blocking, thermal shutdown at 140°C, UVLO at 1.9V, and controlled 0.6ms rise time-critical for reliable hot-plug insertion in HUBs, docking stations, and embedded systems.

Technical Context

The AP2186MPG-13 integrates two independent high-side N-channel MOSFET switches with matched current-limit thresholds (2.1A typ) and separate open-drain FLG outputs. Each channel features independent EN control (active-low), internal sense-FET current monitoring, and thermal foldback that disables output above 140°C with 25°C hysteresis.

Its UVLO circuit ensures switch disable below 1.9V input, preventing erratic behavior during brownout or hot-removal. The 7ms deglitch on FLG outputs suppresses false over-current reports caused by capacitive inrush transients, eliminating need for external RC filtering in typical USB load configurations.

Key Specifications

Pinout & Package

AP2186MPG-13 is housed in an MSOP-8EP (Exposed Pad) package. The exposed pad must be externally connected to GND and thermal mass for optimal θ_JA = 60°C/W performance; it is not intended as primary electrical ground conduction path.

FAQ

What is the function of the exposed pad on the AP2186MPG-13 MSOP-8EP package?

The exposed pad is a thermal enhancement feature requiring external connection to GND and a dedicated copper pour for heat dissipation. It reduces θ_JA to 60°C/W but must not serve as the sole electrical ground path. Soldering the pad improves thermal performance without altering signal integrity or current routing.

Can AP2186MPG-13 drive a 2.1A load continuously?

No. Its recommended maximum continuous load current is 1.5A per channel, as specified in the datasheet. While the current limit trips at 2.1A typ, sustained operation above 1.5A risks exceeding thermal limits due to R_DS(ON) power dissipation, especially in non-ideal PCB layouts or elevated ambient temperatures.

How does the 7ms FLG deglitch work during capacitor charging?

The deglitch timer starts when FLG would otherwise assert low. If the over-current condition clears within 7ms-such as during normal 68µF output capacitor inrush-the FLG output remains high. Only faults persisting beyond 7ms trigger a valid low-level flag, eliminating false interrupts without external components.

Is AP2186MPG-13 compatible with USB Battery Charging (BC) 1.2 specification?

No. AP2186MPG-13 implements USB 2.0 power delivery only and lacks BC1.2-specific D+/D− detection circuitry or dedicated charging port identification logic. It supports standard downstream port (SDP) current limiting but cannot negotiate higher charging currents or identify dedicated charging ports.
