Product details
Overview
AP2822GKATR-G1 from Diodes Incorporated is a 2.0A high-side power distribution switch with integrated N-channel MOSFET, charge pump, and protection circuitry. It delivers 85mΩ RDS(ON) at 5V, supports 2.7–5.5V input, features deglitched open-drain FLAG output for fault reporting, and includes soft-start, over-current fold-back, thermal shutdown, and UVLO - designed for USB bus-powered hubs and hot-plug power rails.
For engineers reviewing the AP2822GKATR-G1 datasheet, AP2822GKATR-G1 pinout, AP2822GKATR-G1 application, or AP2822GKATR-G1 equivalent, key selection criteria include continuous current rating (2.0A), auto-discharge capability via internal pull-low resistor, active-high enable logic, and SOT-23-5 package compatibility with space-constrained USB port designs.
Technical Context
The AP2822GKATR-G1 implements a charge-pump–driven N-channel MOSFET high-side switch to achieve low on-resistance while operating from a single 2.7–5.5V supply. Its current-limit threshold is factory-set to 2.2–3.2A (typ. 2.7A) at VOUT = 4.0V, with fold-back short-circuit current of 1.1A.
It integrates under-voltage lockout (2.5V threshold, 0.2V hysteresis), thermal shutdown at +150°C with +30°C hysteresis, and a deglitched open-drain FLAG pin that asserts low within 5–15ms of over-current or over-temperature events. The device draws only 68µA typical supply current in active mode and 1.0µA max in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85mΩ typ. at VIN = 5V, IOUT = 2.0A - ensures ≤170mV voltage drop at full load, meeting USB 2.0 VBUS regulation. |
| Continuous Current | 2.0A - factory-configured limit for AP2822G variant; enables robust power delivery to USB peripherals without external current sensing. |
| Enable Logic | Active-high - EN pin asserts high to turn on switch; compatible with standard GPIOs without level-shifting. |
| Auto-discharge | Enabled - internal ~150Ω pull-low resistor discharges VOUT after shutdown, preventing floating bus states in USB applications. |
| FLAG Output | Open-drain, deglitched, active-low - signals OCP/OTP faults to host controller with 5–15ms delay; requires external pull-up. |
| Supply Range | 2.7V to 5.5V - supports operation across USB battery (3.3V) and VBUS (5V) domains without auxiliary biasing. |
| Shutdown Current | 1.0µA max - minimizes standby power loss in always-on USB hub or notebook power management systems. |
Pinout & Package
SOT-23-5 (K/KA/KB/KE variants) - 2.9mm × 1.6mm × 1.1mm body, 0.95mm lead pitch, thermally enhanced padless footprint suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K/KA) | FLAG | Fault indicator output; open-drain, active-low, requires external pull-up to report OCP/OTP events to host controller. |
| 2 | GND | Power ground reference for internal circuits and MOSFET source; must be low-impedance connection to system ground plane. |
| 3 (K/KE) | EN | Enable control input; active-high logic (AP2822G); drives internal gate driver when pulled ≥1.6V. |
| 4 (K/KA) | VIN | Main power input; supplies charge pump and internal logic; accepts 2.7–5.5V with UVLO protection. |
| 5 (K/KA) | VOUT | Switched output; connects to load (e.g., USB downstream port); features internal discharge path when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 85mΩ ensures ≤170mV drop at 2.0A, satisfying USB 2.0 VBUS tolerance and minimizing self-heating. |
| Integrated soft-start | Controls turn-on slew rate to limit inrush current during hot-plug events, protecting upstream power sources. |
| Load short protection | Fold-back current limiting reduces short-circuit power dissipation to 1.1A, enabling safe sustained fault handling. |
| No reverse current | Blocks backflow from VOUT to VIN when disabled, eliminating need for external blocking diode in battery-backed systems. |
| Thermal shutdown with hysteresis | +150°C trip with +30°C hysteresis prevents oscillation during overload, allowing automatic recovery after cooling. |
Applications
| USB Bus-Powered Hub | Hot-Plug Notebook Port |
|---|---|
|
Use Scenario: Power switching for downstream USB ports in self-powered or bus-powered hubs. IC Role / Device Role / Timing Role: High-side load switch controlling VBUS delivery per port, with fault reporting via FLAG to hub controller. Use Value: Enables individual port power cycling and over-current isolation without disrupting other ports' operation. |

IC Role / Device Role / Timing Role: Hot-plug–capable power rail manager with soft-start and fast fault response to prevent system brownouts. Use Value: Eliminates mechanical fuses and discrete MOSFET+driver solutions, reducing BOM count and layout area by >40%. |
| Battery-Charger Input Stage | Industrial USB Peripheral Interface |
|
Use Scenario: Input power switching between wall adapter and battery-supplied 5V rail in portable chargers. IC Role / Device Role / Timing Role: Bidirectional isolation switch with reverse-current blocking and UVLO-enforced safe startup. Use Value: Prevents battery drain through charger IC when adapter is disconnected, extending standby time by up to 3×. |

Use Value: Survives repeated hot-insertion cycles and ambient temperatures up to +85°C without derating or external heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2822HKATR-G1 | Same package and specs, but active-low enable logic instead of active-high. | Requires inverted control signal; unsuitable where MCU GPIO is fixed as active-high drive. | Select only if system-level enable polarity matches; no change in protection or performance. |
| TPS22965DRLR | 2.5A rated, 44mΩ RDS(ON), 0.5µA shutdown current, but no integrated auto-discharge resistor. | Lacks internal VOUT pull-down; requires external circuitry for controlled discharge in USB applications. | Preferred for ultra-low quiescent current designs where board space allows added components. |
Compared with AP2822HKATR-G1, the AP2822GKATR-G1 offers direct GPIO compatibility without inversion logic; versus TPS22965DRLR, it trades slightly higher RDS(ON) for integrated auto-discharge - simplifying USB-compliant designs with minimal component count.

FAQ
What is the function of the FLAG pin on AP2822GKATR-G1?
The FLAG pin is an open-drain, deglitched fault indicator that pulls low within 5–15ms during over-current or over-temperature events. It requires an external pull-up resistor to the host controller's logic supply and signals faults to enable software-controlled port disable or retry logic in USB systems.
Does AP2822GKATR-G1 support reverse current blocking?
Yes - the device blocks reverse current flow from VOUT to VIN when disabled, with leakage <1.0µA at VOUT > VIN. This eliminates the need for an external blocking diode in battery backup or dual-source power architectures, preserving efficiency and simplifying layout.
How does the auto-discharge feature operate?
The AP2822GKATR-G1 includes an internal ~150Ω pull-low resistor between VOUT and GND activated upon shutdown. This discharges residual capacitance on the downstream bus within milliseconds, ensuring compliant USB detach behavior and preventing floating VBUS states that could disrupt host enumeration.
Is AP2822GKATR-G1 suitable for automotive applications?
No - the device is rated for –40°C to +85°C ambient operation and lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature range. It is intended for commercial computing, consumer USB, and industrial peripheral interfaces, not under-hood or safety-critical automotive use.
