Product details
Overview
AP22816AKCWT-7 from Diodes Incorporated is a 1.0A single-channel high-side load switch optimized for USB and hot-swap applications, featuring 75mΩ RDS(ON), 2.7V–5.5V input range, integrated output discharge, reverse-current blocking, and active-low enable logic in a TSOT25 package. It delivers controlled power sequencing in ultrabooks and SSDs with fast short-circuit response and 6ms deglitch on the FLG pin.
For engineers reviewing the AP22816AKCWT-7 datasheet, AP22816AKCWT-7 pinout, AP22816AKCWT-7 application, or AP22816AKCWT-7 equivalent, key selection criteria include its 1.0A current limit, 0.6ms typical rise time, UVLO threshold (2.3V typ), thermal shutdown at +150°C, and compatibility with 10μF+ output capacitance for USB compliance.
Technical Context
The AP22816AKCWT-7 implements a thermally protected N-channel MOSFET high-side switch with bi-directional current sensing and integrated deglitch logic on the open-drain FLG output. Its UVLO circuit disables the switch below 2.3V (rising) with 180mV hysteresis, preventing erratic turn-on during brown-out conditions.
Reverse-voltage protection activates when VOUT exceeds VIN by ≥70mV (typ), triggering MOSFET turn-off within 5ms (typ); recovery occurs only after the condition clears and internal hysteresis resets. The discharge function engages upon disable, providing a 140Ω (typ) resistive path to ground for rapid VOUT decay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1.0A - Sustains full-rated load without thermal shutdown under 25°C ambient and proper PCB layout. |
| RDS(ON) | 75mΩ (typ) - Minimizes conduction loss (≤75mW at 1A), enabling use in space-constrained USB ports. |
| Input Voltage Range | 2.7V to 5.5V - Supports single-supply operation across USB 2.0/3.0, 3.3V logic rails, and battery-backed systems. |
| Output Rise Time | 0.6ms (typ) - Ensures controlled inrush limiting into 10μF+ capacitive loads, preventing supply rail collapse. |
| FLG Blanking Time | 6ms (typ) - Suppresses false fault reporting during transient overloads (e.g., hot-plug insertion), eliminating need for external RC filters. |
| Thermal Shutdown Threshold | +150°C (typ) - Protects die integrity during sustained short-circuit events; hysteresis enables auto-recovery after ~40°C cooldown. |
| Reverse Current Blocking | Active - Prevents backfeed from VOUT to VIN when upstream supply is off, critical for multi-rail power domains. |
Pinout & Package
AP22816AKCWT-7 is housed in a RoHS-compliant, lead-free TSOT25 (SOT-25) package with matte tin-plated leads, moisture sensitivity level 1, and thermal resistance RθJA = 123°C/W on standard FR-4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power Ground Reference | Primary return path for internal control circuitry and power switch; must be low-impedance connection to system ground plane. |
| 2 EN | Active-Low Enable Input | Logic-compatible control pin: drives switch ON when pulled low (≤0.5V); must not float-tie to GND or GPIO with pull-down. |
| 3 OUT | Switched Output Terminal | Delivers regulated power to load; requires 0.1μF ceramic + ≥10μF bulk capacitor to GND for stability and USB compliance. |
| 4 IN | Input Power Supply | Accepts 2.7–5.5V source; requires 1μF X7R/X5R ceramic bypass cap placed adjacent to pin to suppress high-frequency noise. |
| 5 FLG | Open-Drain Fault Flag | Asserts low during overcurrent/overtemperature events after 6ms deglitch; requires external pull-up resistor (e.g., 10kΩ to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 140Ω (typ) discharge path ensures VOUT decays to <0.5V within 0.4ms when disabled-eliminates floating voltage on disconnected peripherals. |
| Reverse-Voltage Protection | Triggers at 70mV (typ) VOUT–VIN differential, blocking backfeed before damage occurs in multi-source systems. |
| Auto-Recovering Protections | Overcurrent, short-circuit, and overtemperature faults reset automatically once cleared-no manual reset or power cycle required. |
| UVLO with Hysteresis | Enables only above 2.3V (rising) and disables below 2.12V (falling)-prevents oscillation during slow-ramping supplies. |
| No External Components Required | Full protection suite (discharge, deglitch, UVLO, thermal sense) implemented internally-reduces BOM count and board area. |
Applications
| USB Port Power Control | SSD Power Sequencing |
|---|---|
Use Scenario: Managing power delivery to downstream USB devices during hot-plug events in ultrabooks and docking stations. IC Role / Device Role / Timing Role: High-side load switch controlling VBUS rail with precise inrush limiting and fault isolation. Use Value: Prevents host port damage from capacitive inrush and short circuits while maintaining USB-IF compliance via controlled 0.6ms rise time. | Use Scenario: Enabling/disabling 3.3V power to NAND flash modules in M.2 SSDs during sleep/wake transitions. IC Role / Device Role / Timing Role: Sequenced power gate with reverse-current blocking to isolate SSD from host during suspend. Use Value: Eliminates backfeed leakage that could corrupt flash data or drain host battery during deep sleep states. |
| Notebook System Power Rails | Set-Top Box Peripheral Management |

IC Role / Device Role / Timing Role: Load switch with thermal foldback and auto-recovery for intermittent high-current peripherals. Use Value: Sustains 1.0A peak loads without latch-up, enabling reliable operation even under transient thermal stress. | Use Scenario: Controlling power to HDMI receiver ICs or tuners in consumer set-top boxes with varying load profiles.

Use Value: Provides real-time overcurrent detection (via FLG) to firmware, enabling graceful shutdown before thermal damage occurs. |
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 |
|---|---|---|---|
| AP22816AW5-7 | Same electrical specs but in SOT-25 (W5) package; identical pinout and thermal performance (RθJA = 123°C/W). | No functional difference-used interchangeably where W5 footprint is preferred over KC. | Select based on PCB land pattern compatibility; both support same 1.0A/75mΩ operation and USB hot-swap requirements. |
| TCK107AG,TL | 1.2A rated, 65mΩ RDS(ON), active-high enable, no integrated discharge function, different pinout (SOT-25 variant). | Lacks output discharge and reverse-current blocking-requires external circuitry for safe hot-plug in bidirectional systems. | Choose only if higher current headroom is needed and discharge/reverse-blocking are handled externally. |
Compared with AP22816AKCWT-7, AP22816AW5-7 offers identical functionality in an alternate SOT-25 variant, while TCK107AG,TL trades discharge/reverse-protection for lower RDS(ON) and higher current-but increases design complexity due to missing integrated safety features.

FAQ
What is the maximum continuous output current rating for AP22816AKCWT-7?
The AP22816AKCWT-7 is rated for 1.0A continuous output current under recommended operating conditions (TA ≤ +85°C, proper PCB copper area). Its overcurrent limit is 1.5A (typ) with auto-recovery, and short-circuit current is clamped to 0.5A (typ) to prevent damage during faults.
Does AP22816AKCWT-7 require external components for basic operation?
No-AP22816AKCWT-7 operates fully with only two external capacitors: a 1μF ceramic on IN-GND and a 0.1μF ceramic plus ≥10μF bulk capacitor on OUT-GND. The 6ms FLG deglitch, UVLO, thermal shutdown, and discharge functions are all internal and require no additional passives.
How does the reverse-voltage protection function in AP22816AKCWT-7?
When VOUT exceeds VIN by ≥70mV (typ), the device disables the internal MOSFET within 5ms (typ) to block reverse current flow. Recovery occurs automatically once VOUT falls below VIN + 35mV (hysteresis), restoring normal forward conduction without user intervention.
Can AP22816AKCWT-7 be used in automotive applications?
AP22816AKCWT-7 is not AEC-Q100 qualified. For automotive use, Diodes Incorporated offers pin-compatible AEC-Q100 variants (e.g., AP22816QKCWT-7) with PPAP support, IATF 16949 manufacturing, and extended temperature validation. Standard AP22816AKCWT-7 is intended for commercial/industrial environments (–40°C to +85°C).
