Product details
Overview
AP22816BKBWT-7 from Diodes Incorporated is a single-channel, active-low enable, high-side load switch optimized for USB 2.0/3.x and hot-swap applications. It delivers 1.0A continuous output current with 75mΩ RDS(ON), integrated reverse-current blocking, overcurrent/overtemperature/short-circuit protection with auto-recovery, and 0.6ms typical soft-start rise time. Used in Ultrabook power sequencing and SSD power rails.
For engineers reviewing the AP22816BKBWT-7 datasheet, AP22816BKBWT-7 pinout, AP22816BKBWT-7 application, or AP22816BKBWT-7 equivalent, key selection criteria include active-low EN logic compatibility, 2.7–5.5V input range, 6ms FLG deglitch timing, integrated output discharge, and TSOT25 package thermal performance (RθJA = 123°C/W).
Technical Context
The AP22816BKBWT-7 implements a thermally robust N-channel MOSFET high-side switch with bidirectional current sensing and UVLO (2.3V typ. turn-on, 180mV hysteresis). Its fault management uses a dedicated open-drain FLG pin with 6ms blanking to suppress false triggers during capacitive inrush.
It integrates reverse-voltage protection (trip at 70mV VOUT–VIN), output discharge (140Ω typical RDIS, 0.4ms tDIS), and thermal shutdown at +150°C with +40°C hysteresis-enabling autonomous recovery without external circuitry in transient overload conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0/3.x bus voltage tolerance and legacy 3.3V/5V system rails. |
| RDS(ON) | 75mΩ (typ.) at 5V, 1A - enables <100mV drop at rated load, minimizing power loss and self-heating in compact layouts. |
| Output Current Limit | 1.5A (typ.) - clamps sustained overloads to prevent damage while maintaining partial functionality under short-circuit. |
| FLG Blanking Time | 6ms (typ.) - filters transient inrush spikes from heavy capacitive loads (e.g., 120μF SSD rail), eliminating need for external RC filtering. |
| Output Discharge Resistance | 140Ω (typ.) - safely discharges 10μF output capacitance to <0.5V in ≤0.4ms, preventing backfeed and ensuring clean power-down sequencing. |
| Thermal Shutdown Threshold | +150°C with +40°C hysteresis - allows safe cyclic operation during prolonged overload, enabling self-recovery without host intervention. |
| Reverse-Voltage Trip Point | 70mV (typ.) - blocks reverse current when VOUT exceeds VIN by ≥70mV, protecting upstream sources in multi-rail systems. |
Pinout & Package
AP22816BKBWT-7 is housed in a RoHS-compliant, lead-free TSOT25 (SOT-25) package (2.9mm × 1.6mm × 0.8mm), featuring matte tin-plated leads solderable per MIL-STD-202 Method 208 (e3). Thermal resistance is 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-inductance connection to system ground plane. |
| 2 EN | Active-Low Enable Input | Drives internal driver when pulled low (≤0.5V); high-impedance when pulled high (>1.5V); requires pull-up for default-off behavior. |
| 3 OUT | Switched Output Terminal | Connects to load; requires 0.1μF ceramic + ≥10μF bulk capacitor to GND for stability and short-circuit energy absorption. |
| 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 host GPIO. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 140Ω internal discharge FET ensures controlled VOUT decay to <0.5V within 0.4ms, eliminating need for external discharge resistors in space-constrained designs. |
| Auto-Recovery Protection | Overcurrent, short-circuit, and overtemperature faults trigger automatic current limiting or shutdown, then resume normal operation once fault clears-no reset required. |
| Reverse-Current Blocking | Prevents backflow from VOUT to VIN when VOUT > VIN +70mV, critical for isolated power domains and battery-backed subsystems. |
| UVLO with Hysteresis | Enables switching only above 2.3V (rising) and disables below 2.12V (falling), preventing erratic operation during brown-out or hot-plug insertion. |
| ESD Robustness | 2kV HBM / 500V CDM rating ensures reliability during board handling and system integration without additional protection components. |
Applications

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 |
|---|---|---|---|
| AP22816AKBWT-7 | Identical specs except active-high EN logic (VIL ≤ 0.5V, VIH ≥ 1.5V) | Requires inverted GPIO drive or level-shifting if host MCU lacks configurable polarity | Select when system control logic natively supports active-high enable signaling. |
| TCK107AG,LF | Higher RDS(ON) (100mΩ), no integrated discharge, 2.5–5.5V range, 1.2A limit | Lacks reverse-current blocking and FLG deglitch; requires external discharge resistor | Choose for cost-sensitive, non-USB applications where 0.6ms soft-start and reverse blocking are not mandatory. |
Compared with AP22816AKBWT-7, AP22816BKBWT-7 simplifies interface design in systems with active-low reset/enable buses; versus TCK107AG,LF, it delivers superior system-level robustness through integrated discharge, reverse-current blocking, and fault blanking-reducing BOM count and layout area.

FAQ
What is the function of the FLG pin on AP22816BKBWT-7?
The FLG pin is an open-drain fault flag that asserts low (≤0.4V) when overcurrent, short-circuit, or overtemperature conditions occur. It incorporates a 6ms deglitch timeout to ignore transient inrush events, and remains low until all faults are cleared. An external pull-up resistor (typically 10kΩ) is required to interface with host microcontroller GPIO inputs.
Does AP22816BKBWT-7 require external components for basic operation?
No external components are required for core switching functionality. However, Diodes recommends a 1μF ceramic capacitor between IN and GND, a 0.1μF ceramic + ≥10μF bulk capacitor between OUT and GND, and a pull-up resistor on FLG. These ensure stable operation, inrush suppression, fault reporting, and compliance with USB hot-swap specifications.
How does AP22816BKBWT-7 handle reverse current flow?
AP22816BKBWT-7 blocks reverse current by turning off the internal N-MOSFET when VOUT exceeds VIN by ≥70mV (typ.), detected by an internal comparator. This occurs within 5ms (typ.) and prevents backfeed into upstream supplies-critical for multi-rail systems and battery-powered devices where cross-conduction must be avoided.
Can AP22816BKBWT-7 be used in automotive applications?
AP22816BKBWT-7 is not AEC-Q100 qualified and is intended for commercial/industrial applications. For automotive use, Diodes offers AEC-Q100 qualified alternatives such as the AP22653Q (TSOP-6, 3A) or AP22916Q (TDFN-8, 6A).
