Product details
Overview
AP2176SG-13 from Diodes Incorporated is a dual-channel, 1.5A current-limited high-side power switch optimized for USB 2.0 hot-swap applications. It features active-high enable inputs, 90mΩ typical RDS(ON) (MSOP-8EP), 2.7V–5.5V input range, and integrated short-circuit/thermal protection with 7ms deglitch on open-drain FLG outputs. Used in USB hubs and portable computing peripherals to manage power sequencing and fault isolation.
For engineers reviewing the AP2176SG-13 datasheet, AP2176SG-13 pinout, AP2176SG-13 application, or AP2176SG-13 equivalent, key selection criteria include enable polarity (active-high), dual independent channel control, reverse current blocking, UVLO threshold (1.9V typ), and thermal shutdown at +140°C with +25°C hysteresis.
Technical Context
The AP2176SG-13 integrates two independent N-channel MOSFET high-side switches with matched current-limit circuitry, each capable of delivering up to 1.0A continuous load current. Its internal sense-FET architecture enables accurate 1.5A current limiting without external resistors while maintaining low conduction loss.
Each channel implements independent overcurrent detection with 7ms deglitch timing, open-drain FLG reporting, and under-voltage lockout (1.6–2.5V range) that disables switching until VIN exceeds ~1.9V. Thermal shutdown activates at +140°C junction temperature with +25°C hysteresis, enabling automatic recovery after fault removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.5A typical - clamps output current during overload without device damage |
| RDS(ON) | 90mΩ typical (MSOP-8EP, 5V, 1A) - minimizes power loss and self-heating at full load |
| Input Voltage Range | 2.7V–5.5V - supports USB 2.0 VBUS and wide-input industrial rails |
| Rise Time | 0.6ms typical - controls inrush current during hot-plug insertion |
| Shutdown Current | 1µA max - preserves battery life in always-on USB peripheral designs |
| UVLO Threshold | 1.9V typical - prevents erratic switching during brown-out or power-up sequencing |
| Thermal Shutdown | +140°C with +25°C hysteresis - enables autonomous recovery after sustained overload |
Pinout & Package
AP2176SG-13 is packaged in SO-8 (surface-mount, 150°C max junction rating) with exposed pad not electrically connected - must be soldered to PCB ground plane for thermal management only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 / EN2 | Channel 1 / Channel 2 enable input | Active-high logic control; drives internal gate driver when pulled ≥2V |
| FLG1 / FLG2 | Channel 1 / Channel 2 fault report | Open-drain output asserted low after 7ms deglitch upon overcurrent or overtemperature |
| OUT1 / OUT2 | Channel 1 / Channel 2 output | Switched high-side output; supports reverse current blocking when disabled |
| IN | Power input | Common input rail for both channels; accepts 2.7V–5.5V with UVLO protection |
| GND | Ground reference | Analog and power ground; connects to PCB ground plane and exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent channel control | EN1/EN2 and FLG1/FLG2 pins allow per-port enable/disable and fault monitoring in USB hubs |
| Reverse current blocking | Prevents backfeed from powered downstream loads into upstream supply during disable or fault |
| 7ms FLG deglitch | Eliminates false fault reporting from capacitive inrush transients - no external RC needed |
| Low RDS(ON) at 3.3V | 120mΩ typical enables efficient operation from single-cell Li-ion or 3.3V system rails |
| UL Recognized & CB Certified | E322375 file number and IEC60950-1 certification support safety-compliant end-equipment design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2166SG-13 | Identical specs except active-low EN inputs | Requires inverted enable logic from host MCU or level-shifting circuitry | Select when system control logic uses active-low signaling or legacy USB hub reference designs |
| TCK112G,LF | Single-channel, 2.5A rated, 45mΩ RDS(ON), no FLG output | Lacks dual-channel integration and fault reporting - requires two devices and external monitoring | Choose only if higher current per channel (>1.5A) or lower on-resistance is mandatory and FLG reporting is unnecessary |
Compared with AP2166SG-13, the AP2176SG-13 eliminates need for external inverters in active-high control systems; compared with TCK112G, it delivers dual-channel integration, fault visibility, and USB-optimized timing - reducing board area and firmware complexity.

FAQ
What is the maximum continuous load current per channel for AP2176SG-13?
The AP2176SG-13 supports 1.0A maximum continuous load current per channel under recommended operating conditions (TA ≤ +85°C, proper PCB thermal layout). Although its current limit is 1.5A, continuous operation above 1.0A risks exceeding thermal limits in SO-8 packaging without enhanced heatsinking.
Does AP2176SG-13 require external components for overcurrent deglitching?
No. The AP2176SG-13 integrates a 7ms internal deglitch timer on both FLG1 and FLG2 outputs, preventing false fault reporting from capacitive inrush transients. No external RC networks or filtering components are required for reliable overcurrent detection.
Can AP2176SG-13 operate from a 3.3V supply rail?
Yes. The AP2176SG-13 operates across 2.7V–5.5V input voltage range. At 3.3V, RDS(ON) is 120mΩ typical (SO-8) and 120mΩ typical (MSOP-8EP), enabling efficient 1A switching with <150mW conduction loss per channel.
How does reverse current blocking function in AP2176SG-13?
When disabled, the internal MOSFET body diode is reverse-biased due to integrated charge pump and gate control circuitry, blocking current flow from OUT to IN. This prevents backfeed from powered downstream loads - critical for USB OTG and multi-rail systems where VBUS may remain active while upstream supply is off.
