Product details
Overview
AP2151AMP-13 from Diodes Incorporated is a single-channel, active-high, current-limited high-side power switch optimized for USB 2.0 hot-swap applications. It delivers 0.5A continuous load current with 95mΩ typical RDS(ON), 0.8A accurate current limiting, and integrated reverse-current blocking. Used in self-powered USB hubs and LCD monitor port protection, it operates across 2.7V–5.5V input and features 7ms deglitched fault reporting via open-drain FLG.
For engineers reviewing the AP2151AMP-13 datasheet, AP2151AMP-13 pinout, AP2151AMP-13 application, or AP2151AMP-13 equivalent, key selection criteria include thermal shutdown threshold (+140°C), UVLO trip (1.9V typ), rise time (0.6ms typ), shutdown current (1µA max), and package-specific θJA (60°C/W for MSOP-8EP).
Technical Context
The AP2151AMP-13 integrates a low-RDS(ON) N-channel MOSFET with precision current-sense FET architecture-eliminating external sense resistors while maintaining ±15% current-limit accuracy over temperature. Its deglitched FLG output uses internal timing to suppress false triggers from capacitive inrush, requiring no external RC network.
UVLO ensures switch disable below 1.9V input, preventing erratic behavior during brown-out or hot-insertion; thermal protection cycles the output off at +140°C with +25°C hysteresis, enabling safe operation under sustained overload without latch-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 0.8A typical; clamps output to safe level during overload without shutdown, preserving system uptime. |
| RDS(ON) | 95mΩ @ 25°C, 5VIN; minimizes conduction loss and self-heating in compact MSOP-8EP package. |
| Input Voltage Range | 2.7V–5.5V; supports full USB 2.0 bus voltage range and accommodates Li-ion battery-backed systems. |
| FLG Blanking Time | 7ms typical; suppresses false fault reports from transient inrush currents (e.g., 22µF output cap). |
| Thermal Shutdown | +140°C trip with +25°C hysteresis; enables automatic recovery after fault removal without manual reset. |
| Shutdown Current | 1µA max; reduces standby power in always-on USB ports and battery-sensitive portable devices. |
| Turn-On Rise Time | 0.6ms typical; provides controlled voltage ramp to limit inrush surge on hot-plugged peripherals. |
Pinout & Package
AP2151AMP-13 is packaged in MSOP-8EP (exposed pad), offering enhanced thermal performance (θJA = 60°C/W) versus SO-8 or SOT25. The exposed pad must be soldered to PCB ground plane for thermal management but not used as primary current return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for internal circuitry and thermal pad connection point. |
| IN | Power input | 2.7V–5.5V supply input; pins 2 & 3 are internally paralleled for lower impedance. |
| EN | Enable control | Active-high logic input; drives internal driver stage to turn on MOSFET when >2VIN. |
| FLG | Fault indicator | Open-drain output pulled low during over-current or over-temperature events after 7ms blanking. |
| OUT | Switched output | Pins 6 & 7 are paralleled output terminals delivering regulated current to load. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse current blocking | Prevents backflow from output to input when disabled-critical for shared-bus USB hub architectures. |
| Integrated UVLO | Enables reliable hot-plug sequencing by holding switch off until VIN ≥ 1.9V, avoiding partial-power faults. |
| No external components for FLG debouncing | 7ms internal deglitch eliminates need for external RC filter, reducing BOM count and layout area. |
| ESD robustness | 4kV HBM / 15kV IEC 61000-4-2 (with external cap); protects against ESD events in consumer-facing USB ports. |
| Green packaging | Halogen- and antimony-free, lead-free MSOP-8EP meets RoHS 3 and UL E322375 certification. |
Applications
| USB Self-Powered Hub | LCD Monitor Port Protection |
|---|---|
Use Scenario: Desktop PC with downstream USB 2.0 ports powering keyboards, mice, and flash drives. IC Role / Device Role / Timing Role: High-side power switch per port, enabling/disabling VBUS under host controller command with fault reporting. Use Value: Prevents bus-wide shutdown during single-port over-current; FLG signal alerts host controller within 7ms of fault onset. |
Use Scenario: HDMI-equipped LCD monitor with USB upstream/downstream connectivity for peripheral charging. IC Role / Device Role / Timing Role: Isolates USB data/power paths from main 5V rail; controls hot-plug insertion of USB-C accessories. Use Value: 0.6ms rise time limits inrush into monitor's USB port capacitors; reverse-blocking prevents backfeed into display logic. |
| Smartphone Docking Station | Set-Top Box USB Peripheral Interface |
Use Scenario: Docking station supplying power and data to smartphone while connected to HDMI/ethernet. IC Role / Device Role / Timing Role: Enables clean power sequencing to phone's VBUS line only after dock detects valid handshake. Use Value: UVLO ensures switch remains off until dock's 5V rail stabilizes; thermal cycling allows safe operation during extended charging faults. |
Use Scenario: Cable set-top box with front-panel USB port for firmware updates via flash drive. IC Role / Device Role / Timing Role: Provides over-current protection and fault signaling to STB microcontroller during USB enumeration. Use Value: 0.8A current limit matches USB 2.0 spec; 1µA shutdown current preserves standby battery life in always-on devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2151AS-13 | SO-8 package (θJA = 110°C/W); higher thermal resistance than MSOP-8EP; same electrical specs. | Better suited for through-hole prototyping or legacy board layouts with SO-8 footprints. | Select when thermal budget allows higher junction rise or when SO-8 mechanical compatibility is required. |
| TUSB2036IRHBR | Integrated USB 2.0 hub controller + power switches; requires external crystal; 3.3V-only I/O. | Replaces discrete switch + MCU logic; adds enumeration support but increases complexity and BOM cost. | Choose only when full hub functionality (not just power switching) is needed-adds USB protocol stack overhead. |
Compared with AP2151AS-13, the AP2151AMP-13 offers 45% lower thermal resistance for higher ambient operation in space-constrained designs; versus TUSB2036IRHBR, it provides simpler, lower-cost, dedicated power control without USB protocol handling.

FAQ
What is the maximum continuous load current supported by AP2151AMP-13?
The AP2151AMP-13 is rated for 0.5A maximum continuous load current per Diodes' Recommended Operating Conditions. Although its current limit is 0.8A typical, sustained operation above 0.5A risks exceeding thermal limits in the MSOP-8EP package-even with proper PCB thermal vias-due to its 60°C/W θJA. Derating is required above +60°C ambient.
Does AP2151AMP-13 require external components for fault reporting stability?
No. The AP2151AMP-13 integrates a 7ms deglitch timer on the FLG pin, eliminating the need for external RC filters to suppress false over-current reports caused by capacitive inrush transients. This is confirmed in the datasheet's "FLG Response" section and validated across all package variants including MSOP-8EP.
Can AP2151AMP-13 be used in automotive USB applications?
No. AP2151AMP-13 is specified for –40°C to +85°C ambient operation and lacks AEC-Q200 qualification, automotive-grade ESD (e.g., ISO 10605), or extended temperature validation. Its UVLO threshold (1.9V) and thermal shutdown (+140°C) are designed for commercial computing and consumer electronics-not automotive cold-crank or under-hood environments.
How does reverse current blocking function in AP2151AMP-13?
AP2151AMP-13 blocks reverse current flow from OUT to IN when disabled, using internal MOSFET body-diode orientation and gate control. This prevents backfeeding into the upstream 5V rail-a critical requirement in USB hubs where multiple downstream ports share a common VBUS source and must remain isolated.
