Product details
Overview
AP22816BKAWT-7 from Diodes Incorporated is a single-channel, 1.0A-rated, integrated high-side load switch optimized for USB and hot-swap applications. It features 75mΩ RDS(ON), 2.7V–5.5V input range, active-low enable, integrated output discharge, reverse-current blocking, and overcurrent/overtemperature/short-circuit protection with auto-recovery. It delivers controlled power sequencing in Ultrabook and SSD power rails.
For engineers reviewing the AP22816BKAWT-7 datasheet, AP22816BKAWT-7 pinout, AP22816BKAWT-7 application, or AP22816BKAWT-7 equivalent, key selection criteria include its 1.0A current rating, TSOT25 package footprint, 6ms FLG deglitch timing, soft-start rise time (2.1ms typ.), and reverse-voltage trip point (70mV typ.) - all critical for USB-compliant hot-plug reliability.
Technical Context
The AP22816BKAWT-7 implements a thermally protected N-channel MOSFET high-side switch with bi-directional current sensing and UVLO (2.3V rising threshold). Its internal discharge FET activates on disable to sink output capacitance via 170Ω typical RDIS, preventing floating rail conditions.
It uses a deglitched open-drain FLG output (6ms blanking) that asserts low only after sustained overcurrent or overtemperature events, eliminating false triggers from capacitive inrush. The device supports active-low logic-level EN with 0.5V VIL and 1.5V VIH, compatible with 3.3V/5V GPIOs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1.0A - Sustained load capability without thermal shutdown under 85°C ambient and proper PCB layout. |
| RDS(ON) | 75mΩ @ 5V, 25°C - Minimizes conduction loss (75mW at 1A), enabling compact thermal design in TSOT25. |
| Input Voltage Range | 2.7V to 5.5V - Matches USB 2.0/3.0 bus and common 3.3V/5V system rails without external regulation. |
| tR (Rise Time) | 2.1ms typ. @ 3.3V - Soft-start limits inrush current into 100μF+ loads, preventing input rail collapse. |
| FLG Blanking Time | 6ms typ. - Suppresses transient overcurrent pulses during plug-in or capacitor charging, avoiding false fault reporting. |
| Reverse-Voltage Trip | 70mV typ. - Blocks reverse current when VOUT > VIN + 70mV, protecting upstream sources in back-powered scenarios. |
| Discharge Resistance | 170Ω typ. - Ensures <0.4ms discharge of 1μF output cap, eliminating residual voltage before re-enable. |
Pinout & Package
AP22816BKAWT-7 is housed in a RoHS-compliant, lead-free TSOT25 (SOT-25) package - a 5-pin, 2.9mm × 1.6mm surface-mount outline with e3 matte tin plating and J-STD-020 Level 1 moisture sensitivity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be connected to low-impedance PCB ground plane for thermal and noise control. |
| 2 | EN | Active-low enable input; pulled low disables switch and activates discharge path; requires no external pull-down. |
| 3 | OUT | Switched output node; connects to 0.1μF ceramic + ≥10μF bulk capacitor; reverse-current protected. |
| 4 | IN | Input power rail (2.7–5.5V); requires 1μF X7R/X5R ceramic bypass close to pin to suppress transients. |
| 5 | FLG | Open-drain fault flag; sinks current when overcurrent/overtemperature occurs after 6ms deglitch window. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 170Ω internal discharge path ensures rapid, controlled VOUT decay (<0.4ms for 1μF), eliminating need for external resistor. |
| Auto-Recovery Protections | Overcurrent, short-circuit, and overtemperature faults self-clear once condition is removed - no manual reset required. |
| Reverse-Current Blocking | Prevents backflow from VOUT to VIN when VOUT exceeds VIN by ≥70mV, protecting upstream regulators. |
| UVLO with Hysteresis | Turns on only above 2.3V (rising), turns off below 2.12V (falling); prevents erratic switching near brown-out thresholds. |
| Thermally Robust Layout | TSOT25 RθJA = 123°C/W enables 1.0A operation at +85°C ambient with minimal copper area (1"×1" 2oz FR-4). |
Applications
| USB 3.0 Port Power Control | SSD Power Sequencing |
|---|---|
Use Scenario: Hot-plug insertion of USB peripherals into Ultrabook or docking station ports. IC Role / Device Role / Timing Role: High-side load switch controlling 5V bus power delivery with inrush limiting and short-circuit robustness. Use Value: Prevents host port damage from capacitive inrush or cable shorts while ensuring clean power-up via 2.1ms soft-start. |

IC Role / Device Role / Timing Role: Single-channel power distribution switch with discharge function for safe power-down sequencing. Use Value: Eliminates residual VOUT after disable (<0.4ms), preventing data corruption during hot-removal or firmware updates. |
| Notebook Subsystem Isolation | Set-Top Box USB Hub Management |
Use Scenario: Independent power gating of Wi-Fi/BT modules or display backlight drivers in thin-and-light notebooks. IC Role / Device Role / Timing Role: Load switch providing reverse-current isolation and thermal fault containment per subsystem. Use Value: Blocks backfeed from powered peripherals into disabled subsystems, improving overall system power integrity. |
Use Scenario: Per-port power management in multi-USB set-top box front-panel hubs.

Use Value: Enables software-driven port disable and diagnostics via FLG signal, reducing field failure root-cause analysis time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCK107AG,365 (Toshiba) | 1.2A rating, 65mΩ RDS(ON), active-high EN only, no integrated discharge FET. | Lacks output discharge; requires external 10kΩ resistor for VOUT bleed, increasing BOM count and board space. | Choose if higher current and lower RDS(ON) outweigh need for discharge functionality and active-low EN compatibility. |
| TPS22916BLYFPR (TI) | 1.0A, 60mΩ RDS(ON), 0.5ms rise time, no reverse-voltage protection, FLG with 10ms blanking. | No reverse-current blocking; unsuitable for back-powered USB or shared-rail systems where VOUT may exceed VIN. | Prefer when ultra-fast turn-on is critical and reverse-voltage risk is absent; verify system-level backfeed paths separately. |
Compared with TCK107AG and TPS22916BLYFPR, AP22816BKAWT-7 uniquely combines active-low EN, integrated discharge, and 70mV reverse-voltage trip in a TSOT25 package - making it optimal for space-constrained, USB-compliant hot-swap designs requiring full fault autonomy.

FAQ
What is the maximum continuous output current for AP22816BKAWT-7?
The AP22816BKAWT-7 is rated for 1.0A continuous output current under recommended operating conditions (TA ≤ +85°C, proper PCB copper area). Its 75mΩ RDS(ON) limits power dissipation to 75mW at 1A, enabling reliable operation in the TSOT25 package without forced airflow.
Does AP22816BKAWT-7 provide reverse-current protection?
Yes - it blocks reverse current when VOUT exceeds VIN by ≥70mV (typical), turning off the internal MOSFET within 5ms. This prevents backfeed from downstream circuits into the input rail, a critical feature for shared-bus or battery-backed systems.
How does the FLG pin behave during an overcurrent event?
The FLG pin is an open-drain output that pulls low only after a confirmed overcurrent or overtemperature condition persists for ≥6ms (deglitch timeout). It remains low until both faults clear, then releases high-Z. No external pull-up is mandatory but recommended for clean logic interfacing.
Can AP22816BKAWT-7 be used without external discharge components?
Yes - it integrates a dedicated discharge FET with 170Ω typical resistance, enabling full VOUT discharge in <0.4ms for 1μF loads. This eliminates the need for external resistors or MOSFETs, reducing BOM cost and PCB area while ensuring deterministic power-down behavior.
