Product details
Overview
AP2822CKTR-G1 from Diodes Incorporated is a high-side power distribution switch with integrated N-channel MOSFET, charge pump, and protection circuitry. It delivers 1.0A continuous load current, features 85mΩ RDS(ON), operates from 2.7V to 5.5V, and includes soft-start, over-current protection with fold-back, thermal shutdown, and UVLO - designed for USB bus-powered hub power management.
For engineers reviewing the AP2822CKTR-G1 datasheet, AP2822CKTR-G1 pinout, AP2822CKTR-G1 application, or AP2822CKTR-G1 equivalent, key selection criteria include its auto-discharge capability (integrated pull-low resistor), active-high enable logic, 1.0A current rating, and SOT-23-5 footprint compatibility in space-constrained USB peripheral designs.
Technical Context
The AP2822CKTR-G1 implements a charge-pump–driven gate control architecture to fully enhance the internal N-MOSFET across its 2.7–5.5V input range, enabling low RDS(ON) without external bias. Its deglitched open-drain FLAG output signals OCP or OTP faults with 5–15ms delay, synchronized to internal current-sense and thermal monitoring circuits.
UVLO ensures reliable turn-on only above 2.2–3.0V (typ. 2.5V), while soft-start limits inrush current via controlled slew rate on VOUT. The device supports hot-plug operation with reverse-current blocking (<1.0µA leakage when disabled) and fold-back short-circuit current limiting (typ. 0.7A at VOUT = 0V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85 mΩ max at VIN = 5V, IOUT = 2.0A - meets USB voltage-drop requirements under full load |
| Continuous Load Current | 1.0 A (AP2822C variant) - rated for sustained USB downstream port power delivery |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with USB 2.0/3.0 VBUS and single-cell Li-ion systems |
| Enable Logic | Active-high EN pin - simplifies direct interface with USB controller GPIOs |
| FLAG Output | Open-drain, deglitched, active-low - provides noise-immune fault signaling to host controller |
| Auto-discharge | Integrated 100–200 Ω pull-low resistor on VOUT - ensures rapid output discharge after disable |
| Quiescent Current | 68 µA typ. - minimizes standby power in always-on USB hub applications |
Pinout & Package
SOT-23-5 package (K variant), 2.9 mm × 1.6 mm × 1.1 mm body, 0.95 mm lead pitch, RoHS-compliant and halogen-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | FLAG | Open-drain fault indicator - requires external pull-up; asserts low on OCP/OTP |
| 2 | GND | Power ground reference - shared return path for MOSFET source and internal circuitry |
| 3 | EN | Active-high enable input - logic high >1.6V enables switch; low <1.0V disables |
| 4 | VIN | Main power input - connects to USB VBUS or system rail; feeds internal charge pump |
| 5 | VOUT | Switched output - drives USB downstream port; includes internal auto-discharge resistor |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 85 mΩ ensures ≤3% VBUS drop at 1.0A - satisfies USB 2.0 voltage regulation spec |
| Integrated auto-discharge | 100–200 Ω pull-low resistor discharges VOUT within milliseconds after disable - eliminates floating bus lines |
| Fold-back over-current protection | Short-circuit current limited to ~0.7A - prevents thermal runaway during sustained VOUT-to-GND faults |
| UVLO with hysteresis | 2.5V turn-on threshold +0.2V hysteresis - avoids oscillation near brown-out conditions |
| Reverse current blocking | <1.0 µA leakage when disabled - prevents backfeed from powered peripherals into host supply |
Applications
| USB Bus-Powered Hub | Hot-Plug Power Supply |
|---|---|
|

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 |
|---|---|---|---|
| AP2822DKTR-G1 | Active-low enable logic instead of active-high; identical RDS(ON), current rating, and auto-discharge | Requires inverted control signal - suitable where host GPIO is open-drain or shares logic with other active-low peripherals | Select if system-level enable polarity matches DKTR's active-low behavior; no layout change needed |
| AP2822EKTR-G1 | 1.5A continuous rating (vs. 1.0A), same package and feature set; higher ILIMIT threshold (1.65–2.2A) | Supports higher-power USB-C or dual-port configurations; increases thermal margin but raises cost | Choose for future-proofing or multi-port hubs requiring >1.0A per channel; verify PCB copper and thermal relief |
Compared with AP2822DKTR-G1, the CKTR-G1 offers simpler GPIO interfacing in active-high systems; versus AP2822EKTR-G1, it trades current headroom for tighter thermal design and lower BOM cost in 1.0A USB 2.0 applications.

FAQ
What is the purpose of the FLAG pin on AP2822CKTR-G1?
The FLAG pin is an open-drain, deglitched fault indicator that pulls low during over-current or over-temperature events. It requires an external pull-up resistor and provides a noise-immune signal to the host controller, enabling real-time fault detection and recovery without polling. Delay time from fault onset to FLAG assertion is 5–15 ms.
Does AP2822CKTR-G1 support reverse current blocking?
Yes - when disabled, the device blocks reverse current from VOUT to VIN with leakage <1.0 µA. This prevents backfeed from powered peripherals into the host supply, critical for USB compliance and system-level power domain isolation in battery-backed or multi-rail designs.
How does the auto-discharge function work in AP2822CKTR-G1?
The AP2822CKTR-G1 integrates a 100–200 Ω pull-low resistor between VOUT and GND. When the EN pin is deasserted, this resistor actively discharges the output capacitance, bringing VOUT to ground within milliseconds. This eliminates floating bus lines and ensures safe, predictable state transitions during port disable or reset.
Is AP2822CKTR-G1 recommended for new designs?
No - Diodes Incorporated marks AP2822 as "NOT RECOMMENDED FOR NEW DESIGN" with no official alternate part provided. It remains available for legacy support and existing production, but designers should consult Diodes' latest portfolio (e.g., AP280x series) for enhanced features, improved thermal performance, or extended lifecycle assurance.
