Product details
Overview
AP2172MPG-13 from Diodes Incorporated is a dual-channel, 1.5A current-limited high-side power switch with active-high enable logic, designed for USB 2.0-compliant hot-swap applications. It delivers 115mΩ typical RDS(ON) (MSOP-8EP), 0.6ms typical output rise time, and integrated 7ms deglitch on open-drain FLG outputs-enabling robust over-current and thermal protection without external components in laptop docking stations and USB hubs.
For engineers reviewing the AP2172MPG-13 datasheet, AP2172MPG-13 pinout, AP2172MPG-13 application, or AP2172MPG-13 equivalent, this device supports precise current limiting (1.5A typ), reverse current blocking, UVLO (1.9V threshold), and dual independent channel control-critical for reliable power sequencing in consumer electronics and embedded USB peripherals.
Technical Context
The AP2172MPG-13 integrates two independent N-channel MOSFET high-side switches with matched current-limit sensing, UVLO circuitry that disables switching below 1.9V, and thermal shutdown at 140°C with 25°C hysteresis. Each channel features dedicated EN and FLG pins, enabling per-port fault reporting and discrete enable control.
Its internal deglitch timer (7ms typ) filters transient over-current events caused by capacitive loads, while the 115mΩ RDS(ON) (MSOP-8EP, 5V, +25°C) and 1µA max shutdown current support low-power, thermally constrained designs-particularly where board space and thermal management are critical, such as in thin-profile notebooks and portable docking solutions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.5A typical-clamps output during overload to prevent damage to downstream circuitry and upstream supply. |
| RDS(ON) | 115mΩ typical (MSOP-8EP, VIN=5V)-minimizes conduction loss and self-heating at 1A load (≈115mW dissipation). |
| Input Voltage Range | 2.7V to 5.5V-supports full USB 2.0 bus voltage range and accommodates brown-out conditions down to 2.7V. |
| Enable Logic | Active High-simplifies interface with 3.3V/5V GPIOs without level-shifting or inverters. |
| FLG Blanking Time | 7ms typical-suppresses false fault reports from inrush currents of up to 68µF output capacitance. |
| Shutdown Current | 1µA maximum-enables ultra-low quiescent power in battery-backed or always-on standby modes. |
| UVLO Threshold | 1.9V typical-ensures switch remains off during unsafe low-voltage startup or hot-removal, preventing erratic behavior. |
Pinout & Package
AP2172MPG-13 is housed in an MSOP-8EP (Exposed Pad) package, with the exposed pad thermally connected to GND for enhanced heat dissipation (θJA = 60°C/W). Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference and thermal sink | Primary return path for power and signals; exposed pad must be soldered to PCB ground plane for thermal performance. |
| IN | Main power input | Accepts 2.7–5.5V supply; feeds both channels and internal bias circuitry. |
| EN1 / EN2 | Channel 1 / Channel 2 enable inputs | Active-High TTL/CMOS-compatible inputs; independently control each switch with no cross-talk. |
| OUT1 / OUT2 | Switched power outputs | Drive downstream loads (e.g., USB ports); include reverse-current blocking to isolate powered peripherals. |
| FLG1 / FLG2 | Open-drain fault indicators | Assert low (with 30–50Ω pull-down strength) after 7ms deglitch upon over-current or over-temperature event. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables isolated power control per USB port-prevents single-point failure from disabling both ports. |
| Integrated 7ms deglitch on FLG | Eliminates need for external RC filters or microcontroller debouncing logic when monitoring fault status. |
| Reverse current blocking | Prevents backflow from powered downstream devices (e.g., USB peripherals with local caps) into the host supply rail. |
| Thermal shutdown with hysteresis | Shuts down at 140°C and auto-recovers only after cooling ≥25°C-provides self-resetting protection during sustained overload. |
| Green, RoHS-compliant packaging | Halogen- and antimony-free MSOP-8EP meets IEC60950-1 CB Scheme and UL E322375 recognition. |
Applications
| USB 2.0 Dual-Port Hub | Laptop Docking Station |
|---|---|
|
Use Scenario: Power delivery to two downstream USB 2.0 ports with independent over-current detection and reporting. IC Role / Device Role / Timing Role: Dual-channel high-side power switch providing per-port enable, current limiting, and fault flagging.

IC Role / Device Role / Timing Role: Hot-swap power controller with 0.6ms controlled rise time to limit inrush into large output capacitances (e.g., 68µF per port). Use Value: Prevents system brown-out during plug-in and ensures clean power ramp-up across multiple peripheral rails without external soft-start circuitry. |
| Smartphone/Tablet Dock | Set-Top Box USB Expansion |
|
Use Scenario: Adding USB host functionality to mobile devices via accessory docks with strict thermal and size constraints. IC Role / Device Role / Timing Role: Compact high-side switch (MSOP-8EP) delivering 1.5A per channel with 60°C/W θJA for passive thermal management. Use Value: Supports fanless, sealed enclosure designs by maintaining safe junction temperature (<125°C) at 1A continuous load in +70°C ambient. |
Use Scenario: Adding external USB storage or HID peripherals to set-top boxes requiring robust short-circuit immunity. IC Role / Device Role / Timing Role: Fault-tolerant power switch with UVLO and thermal cycling protection for unattended operation. Use Value: Eliminates field failures due to accidental short circuits on USB ports-auto-recovers after fault removal without host intervention. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IPWR | USB 2.0 transceiver + integrated hub controller-not a standalone power switch; requires external VBUS switches. | Designed for full hub IC implementation; lacks independent current-limit reporting per port. | Select only if full USB protocol handling (enumeration, packet routing) is required alongside power control. |
| TPS2051BDBVR | Single-channel, 500mA current limit, SOT-23-5 package; no FLG deglitch or reverse blocking. | Requires two units for dual-port use; higher total RDS(ON) (200mΩ per channel) and no thermal hysteresis. | Choose only for cost-sensitive, low-current (<500mA) applications where dual independent FLG reporting is unnecessary. |
Compared with TUSB2036IPWR and TPS2051BDBVR, the AP2172MPG-13 uniquely combines dual-channel 1.5A current limiting, per-port FLG with hardware deglitch, reverse current blocking, and MSOP-8EP thermal efficiency-making it optimal for compact, self-protected USB power distribution where protocol awareness is not required.

FAQ
What is the maximum continuous load current per channel for AP2172MPG-13?
The AP2172MPG-13 supports a recommended maximum continuous load current of 1.0A per channel under normal operating conditions (TA ≤ +85°C, VIN = 5V). Its 1.5A current limit is a protective trip threshold-not a sustained rating-and thermal derating applies above +70°C ambient due to its 60°C/W θJA in MSOP-8EP.
Does AP2172MPG-13 require external components for over-current protection?
No. The AP2172MPG-13 integrates all necessary circuitry for over-current protection-including current-sense FETs, deglitch timing (7ms typ), and open-drain FLG outputs-requiring zero external components for basic fault detection and current limiting. Only input/output ceramic bypass capacitors (0.1µF) are recommended for stability.
Can AP2172MPG-13 be used in automotive applications?
The AP2172MPG-13 is specified for −40°C to +85°C ambient operation and carries UL/IEC safety certifications, but it is not AEC-Q200 qualified and lacks extended temperature grade (−40°C to +125°C) or automotive-specific reliability testing. It is intended for commercial/industrial USB power applications-not under-hood automotive systems.
How does the FLG output behave during a short-circuit event?
Upon detecting over-current or over-temperature, the FLG pin transitions low after a nominal 7ms deglitch period and remains low until both fault conditions are fully cleared. During thermal shutdown cycling, FLG stays asserted low throughout each off-cycle and only releases after the die cools ≥25°C below the 140°C trip point and load current returns to safe levels.
