Product details
Overview
AP22816BKCWT-7 from Diodes Incorporated is a single-channel, active-low enable, high-side load switch optimized for USB 2.0 hot-swap applications with 1.0A current rating, 75mΩ RDS(ON), 2.7–5.5V input range, and integrated output discharge. It delivers controlled power sequencing in ultrabooks and SSDs while providing reverse-current blocking, overcurrent/overtemperature/short-circuit protection with auto-recovery, and 6ms deglitched fault reporting.
For engineers reviewing the AP22816BKCWT-7 datasheet, AP22816BKCWT-7 pinout, AP22816BKCWT-7 application, or AP22816BKCWT-7 equivalent, this page provides verified functional identity, TSOT25 package mapping, confirmed active-low EN logic, real-world timing (2.1ms typical rise time), and validated alternative parts for USB power distribution design.
Technical Context
The AP22816BKCWT-7 implements an N-channel MOSFET high-side switch with integrated current-sense FET for overcurrent detection without external resistors. Its UVLO threshold is 2.3V (rising) with 180mV hysteresis, ensuring reliable turn-on only after stable rail establishment.
Thermal shutdown activates at +150°C with +40°C hysteresis, enabling safe thermal cycling during sustained overload. The 6ms deglitch on the open-drain FLG pin prevents false fault assertions during capacitive inrush, and the 140Ω internal discharge resistor ensures VOUT falls below 0.5V within 0.4ms when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0 bus voltage range and 3.3V/5V system rails. |
| RDS(ON) | 75mΩ (typ.) - enables <100mV drop at 1.0A, minimizing power loss and self-heating in compact layouts. |
| Output Current Rating | 1.0A continuous - matches AP22816 variant; sufficient for USB peripheral ports and SSD VCC power rails. |
| Enable Polarity | Active-low (EN̅) - compatible with standard GPIOs asserting low to enable power delivery. |
| Rise Time (tR) | 2.1ms (typ.) - soft-start limits inrush current into 100μF+ loads, preventing input rail collapse. |
| FLG Blanking Time | 6ms (typ.) - suppresses transient overcurrent events (e.g., capacitor charging) without external filtering. |
| Discharge Resistance | 140Ω (typ.) - actively discharges output capacitance to <0.5V in ≤0.4ms, eliminating floating voltage hazards. |
Pinout & Package
AP22816BKCWT-7 is housed in a RoHS-compliant, Green, matte tin-plated TSOT25 (SOT-25) package (3.0mm × 1.7mm × 0.9mm), rated Moisture Sensitivity Level 1 per J-STD-020.
| 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 | IN | Input voltage supply pin; requires 1μF ceramic bypass capacitor placed adjacent to minimize high-frequency ringing. |
| 3 | OUT | Switched output; connects to load and ≥10μF bulk capacitor (USB) plus 0.1μF ceramic for stability and short-circuit immunity. |
| 4 | EN̅ | Active-low enable; driven low (≤0.5V) to turn on switch; must not float-pull-down recommended if unused. |
| 5 | FLG | Open-drain fault flag; pulls low during overcurrent/overtemperature events after 6ms deglitch; requires external pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 140Ω internal discharge path reduces VOUT to <0.5V in ≤0.4ms-eliminates need for external bleed resistor in space-constrained designs. |
| Reverse-Voltage Protection | Triggers MOSFET turn-off when VOUT exceeds VIN by ≥70mV (typ.), preventing backfeed damage in multi-rail systems. |
| Auto-Recovery Protections | Overcurrent, short-circuit, and overtemperature faults self-clear once condition is removed-no manual reset required. |
| UVLO with Hysteresis | 2.3V turn-on / 2.12V turn-off thresholds prevent oscillation near brownout conditions during hot-plug insertion. |
| ESD Robustness | 2kV HBM / 500V CDM rating allows handling in standard assembly environments without special ESD controls. |
Applications
| USB 2.0 Peripheral Port Power | Ultrabook Power Sequencing |
|---|---|

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 |
|---|---|---|---|
| AP22816AKCWT-7 | Active-high enable (EN), identical RDS(ON), current rating, and protection features. | Requires high-asserted GPIO instead of low-asserted; no change in USB/SSD functionality. | Select when system MCU outputs active-high enable signals or shares enable logic with other active-high peripherals. |
| TCK107AG,LF | 1.2A rating, 60mΩ RDS(ON), 1.8–5.5V input, but lacks integrated discharge and reverse-voltage protection. | Suitable for simpler hot-swap where discharge and backfeed blocking are handled externally. | Choose only if lower RDS(ON) outweighs loss of integrated protections and board area savings from missing discharge resistor. |
Compared with AP22816BKCWT-7, the AP22816AKCWT-7 offers identical performance with inverted logic interface, while TCK107AG,LF trades integrated protections for marginally lower conduction loss-making the AP22816BKCWT-7 optimal for USB-compliant, space-constrained, and safety-critical load switching.

FAQ
What is the function of the FLG pin on AP22816BKCWT-7?
The FLG pin is an open-drain fault indicator that asserts low (≤0.4V) when overcurrent, short-circuit, or overtemperature conditions occur, after a 6ms deglitch timeout. It remains low until all fault conditions clear and requires an external pull-up resistor (typically 10kΩ) to VIN or system logic rail. This pin enables firmware monitoring without additional sensing components.
Does AP22816BKCWT-7 require external components for basic operation?
No external components are required for core switching functionality. However, Diodes specifies mandatory external capacitors: a 1μF ceramic capacitor between IN and GND, a 0.1μF ceramic capacitor between OUT and GND, and ≥10μF bulk capacitance on OUT for USB applications. These ensure stability, inrush control, and fault resilience-omitting them risks input ringing or device damage during short circuits.
How does the active-low enable (EN̅) behave during power-up?
The EN̅ pin must be held low (≤0.5V) to enable the switch and high (≥1.5V) to disable it. During system power-up, it is recommended to hold EN̅ low until VIN stabilizes above 2.7V and then assert the enable signal. Leaving EN̅ floating may cause unpredictable switching due to noise coupling; a 100kΩ pull-down resistor is advised if GPIO control is inactive.
Can AP22816BKCWT-7 be used in automotive applications?
AP22816BKCWT-7 is not AEC-Q100 qualified and is intended for commercial-grade applications including notebooks, SSDs, and consumer electronics. For automotive use, Diodes offers AEC-Q100 qualified alternatives such as the AP22651Q-contact Diodes or Aetrix for PPAP-capable, IATF 16949-manufactured load switches meeting automotive temperature and reliability requirements.
