Product details
Overview
AP2171MPG-13 from Diodes Incorporated is a single-channel, active-high enable, current-limited high-side power switch optimized for USB 2.0 hot-swap applications. It delivers 1.5A accurate current limiting, 95mΩ on-resistance at 5V, and integrated short-circuit/thermal protection with 7ms deglitch on the open-drain FLG output - used in laptop USB ports and set-top-box power distribution.
For engineers reviewing the AP2171MPG-13 datasheet, AP2171MPG-13 pinout, AP2171MPG-13 application, or AP2171MPG-13 equivalent, key selection criteria include enable polarity (active-high), thermal shutdown threshold (140°C), UVLO trip (1.9V typ), reverse current blocking capability, and compatibility with SO-8/MSOP-8EP/SOT25/U-DFN2018-6 footprint families.
Technical Context
The AP2171 implements a monolithic N-channel MOSFET high-side switch with integrated current-sense FET architecture - eliminating external sense resistors while maintaining precise 1.5A overcurrent limiting across -40°C to +85°C. Its UVLO circuit ensures turn-on only above 1.9V and immediate shutdown below 1.6V, supporting robust hot-plug sequencing.
Thermal protection uses die-temperature sensing with 140°C trip and 25°C hysteresis, enabling automatic cycling during sustained overload. The 7ms FLG deglitch window suppresses false fault reporting from capacitive inrush transients, and the 0.6ms typical rise time enables controlled voltage ramping without external RC networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.5A typical - clamps output current precisely during overload or short-circuit, preventing damage to downstream loads and upstream supply. |
| RDS(ON) | 95mΩ at VIN = 5V, TA = +25°C - minimizes conduction loss and self-heating in 1A continuous load applications. |
| Enable Polarity | Active-high - simplifies interface with 3.3V/5V logic controllers without level-shifting or inversion circuitry. |
| UVLO Threshold | 1.9V typical - ensures switch remains off until input rail stabilizes, critical for reliable hot-insertion in USB host systems. |
| FLG Blanking Time | 7ms typical - filters transient inrush currents (e.g., from 68µF output caps), eliminating need for external debounce components. |
| Shutdown Current | 1µA max - enables ultra-low-power standby in battery-backed or energy-sensitive embedded systems. |
| Reverse Leakage | 1µA max at VOUT = 5V, VIN = 0V - blocks backfeed from powered loads into disabled input rails. |
Pinout & Package
AP2171MPG-13 is supplied in MSOP-8EP (exposed pad) package - thermally enhanced variant with 60°C/W junction-to-ambient thermal resistance when mounted per Diodes' recommended layout (2oz copper, thermal vias to ground plane).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT | Power output node - dual pins internally connected; must be tied together externally for full 1A current handling. |
| 3 | GND | Analog/digital ground reference and primary thermal path - exposed pad must be soldered to PCB ground plane. |
| 4 | EN | Active-high enable input - drives internal driver stage; accepts 2.0V–5.5V logic high to activate switch. |
| 5 | FLG | Open-drain fault indicator - pulled low during overcurrent or thermal shutdown; requires external pull-up for system monitoring. |
| 6, 7 | IN | Power input node - dual pins internally connected; must be tied together externally for low-inductance VIN routing. |
| 8 | NC | No internal connection - electrically isolated; recommended to tie to OUT for EMI reduction and mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Controlled Rise Time | 0.6ms typical - limits inrush dv/dt to prevent bus droop and contact arcing during hot-plug insertion. |
| Integrated Thermal Shutdown | 140°C trip with 25°C hysteresis - enables autonomous recovery after fault removal without host intervention. |
| Reverse Current Blocking | Active MOSFET body-diode isolation - prevents backflow from powered peripherals into disabled upstream supplies. |
| ESD Robustness | 4kV HBM - protects against handling-induced ESD events during assembly and field service. |
| Green Packaging | Halogen- and antimony-free, lead-free, RoHS-compliant - meets IEC60950-1 CB Scheme and UL E322375 requirements. |
Applications
| USB Host Port Protection | Set-Top Box Power Distribution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current-limited power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2161MPG-13 | Active-low enable; identical RDS(ON), current limit, and protection features. | Requires inverted control signal - suitable where host MCU GPIO is low-active or open-drain. | Select when system logic naturally drives low to enable power; no change needed to thermal, timing, or protection behavior. |
| TCK112G,LF | 1.2A current limit, 120mΩ RDS(ON), 1.8V UVLO, no FLG output. | Lacks fault reporting and deglitch - requires external monitoring circuitry for overcurrent detection. | Choose only if lower cost and absence of FLG is acceptable; not drop-in due to missing diagnostic capability. |
Compared with AP2161MPG-13, the AP2171MPG-13 eliminates need for external inverters in active-high control systems; compared with TCK112G, it provides integrated fault visibility and tighter current accuracy - critical for USB-compliant designs requiring real-time overload response.

FAQ
What is the maximum continuous load current supported by AP2171MPG-13?
The AP2171MPG-13 supports 1.0A maximum continuous load current per Diodes' Recommended Operating Conditions - despite its 1.5A current-limit threshold, this derated value ensures safe operation within thermal limits across -40°C to +85°C ambient, especially in MSOP-8EP package with 60°C/W θJA.
Does AP2171MPG-13 require external components for basic operation?
No external components are required for core switching functionality. A 0.1µF ceramic bypass capacitor between IN and GND is recommended for stability, and an external pull-up resistor on FLG is needed only if fault monitoring is implemented - all protection, timing, and deglitch functions are fully integrated.
Can AP2171MPG-13 be used in battery-powered applications?
Yes - its 1µA maximum shutdown current and 45µA typical enabled quiescent current make it suitable for battery-backed systems. Combined with reverse current blocking, it prevents battery drain when input is disconnected while output remains biased, extending operational runtime in portable USB accessories.
How does the 7ms FLG deglitch improve system reliability?
The 7ms deglitch prevents false FLG assertion during benign output capacitor charging events - e.g., a 68µF load cap draws >2A peak for <1ms at turn-on. Without deglitch, this would trigger unnecessary fault interrupts; with it, only sustained overloads (>7ms) generate valid FLG signals, reducing firmware complexity and false alarms.
