Product details
Overview
AP2822GKETR-G1-01 from BCD Semiconductor Manufacturing Limited is a high-side power distribution switch with active-high enable, 2.0A continuous current rating, 85mΩ RDS(ON), integrated over-current and thermal protection, and open-drain FLAG output for USB-compliant hot-plug power management in notebook and motherboard applications.
For engineers reviewing the AP2822GKETR-G1-01 datasheet, AP2822GKETR-G1-01 pinout, AP2822GKETR-G1-01 application, or AP2822GKETR-G1-01 equivalent, this device supports precise current-limited USB VBUS switching, fault reporting to host controllers, and stable operation across -40°C to +85°C ambient with 2.7V–5.5V supply range.
Technical Context
The AP2822GKETR-G1-01 integrates an N-channel MOSFET with charge pump gate drive, enabling low on-resistance (85mΩ typ.) while maintaining logic-level enable compatibility. Its current-limit threshold is fixed at 2.2A (min) to 3.2A (max) under 4.0V VOUT, with fold-back short-circuit response limiting peak fault current to 1.1A.
Functional blocks include UVLO (2.2–3.0V activation), soft-start (500µs turn-on time), deglitched open-drain FLAG output (5–15ms delay to fault assertion), and reverse-current blocking (<1.0µA leakage when disabled). Thermal shutdown triggers at 150°C with 30°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85mΩ typ. at VIN=5V, IOUT=2.0A - meets USB voltage-drop requirements under full load. |
| Continuous Current | 2.0A - fixed rating per part number G variant; enables robust USB bus/hub power delivery. |
| Enable Logic | Active-high - EN pin asserts switch ON when driven ≥1.6V; compatible with standard GPIO outputs. |
| Supply Range | 2.7V–5.5V - supports single-supply operation from USB 5V or lower-voltage battery rails. |
| FLAG Output | Open-drain, deglitched, active-low - signals OCP/OTP faults to USB controller with 5–15ms latency. |
| Shutdown Current | 1.0µA max - minimizes standby power loss in portable systems during sleep states. |
| UVLO Threshold | 2.2–3.0V - prevents erratic switching during brown-out or cold-start conditions. |
Pinout & Package
AP2822GKETR-G1-01 is housed in a standard SOT-23-5 package (2.82mm × 2.92mm × 1.30mm), optimized for space-constrained USB power rail routing and thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | FLAG | Open-drain fault indicator - requires external pull-up; sinks current during OCP/OTP events. |
| 2 | GND | Power ground reference - shared return path for internal protection circuits and MOSFET source. |
| 3 | EN | Active-high enable input - logic HIGH ≥1.6V turns on switch; LOW ≤1.0V disables output. |
| 4 | VIN | Main power input - connects to upstream 2.7–5.5V supply (e.g., USB VBUS or DC-DC output). |
| 5 | VOUT | Switched output - delivers regulated, current-limited power to downstream USB loads or hubs. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 85mΩ typ. reduces conduction loss and self-heating at 2.0A, enabling compact thermal design. |
| USB Compliance | Fully compliant with USB voltage drop and hot-plug timing specifications via soft-start and FLAG signaling. |
| No Reverse Current | Blocks backflow from VOUT to VIN when disabled - eliminates need for external blocking diodes. |
| Fold-back Short Protection | Limits short-circuit current to 1.1A (typ.) - sustains safe operation during sustained VOUT-to-GND faults. |
| Output Pull-Low Resistor | Integrated 100–200Ω discharge path - ensures rapid VOUT ramp-down after disable, preventing floating loads. |
Applications
| USB Bus-Powered Hubs | Notebook USB-C Power Delivery |
|---|---|
|
Use Scenario: Distributing clean, current-limited 5V power to multiple downstream USB peripherals from a single upstream port. IC Role / Device Role / Timing Role: High-side switch controlling VBUS rail with real-time fault detection and reporting to hub controller. Use Value: Prevents overcurrent damage to host port while enabling plug-and-play peripheral enumeration via FLAG-driven interrupt. |
Use Scenario: Managing auxiliary 5V power paths in dual-role USB-C ports where VBUS must be switched independently of CC logic. IC Role / Device Role / Timing Role: Hot-plug power switch with 500µs controlled turn-on and deglitched fault flag for system firmware coordination. Use Value: Eliminates inrush-induced voltage sag and provides deterministic fault isolation without requiring additional sense resistors or comparators. |
| Motherboard USB Port Protection | Battery-Charger Load Switching |
|
Use Scenario: Isolating individual USB ports on desktop/laptop motherboards to prevent cascading failures during cable shorts. IC Role / Device Role / Timing Role: Per-port power switch with thermal shutdown and UVLO, interfacing directly with EC or BMC. Use Value: Enables per-port reset via EN pin and centralized fault monitoring via shared FLAG lines, reducing BOM count vs. discrete solutions. |
Use Scenario: Enabling/disabling charging circuitry powered from a shared 5V rail during battery insertion/removal or thermal throttling. IC Role / Device Role / Timing Role: Load switch with fold-back current limiting and reverse-current blocking to protect charger IC inputs. Use Value: Prevents backfeed into charger IC during battery disconnect and limits fault energy during accidental VOUT short to chassis ground. |
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 |
|---|---|---|---|
| TI TPS22965DRLR | 2.5A rated, 44mΩ RDS(ON), active-high enable, but lacks integrated FLAG output and fold-back short protection. | Requires external fault monitoring circuitry; better suited for non-USB applications needing ultra-low RDS(ON). | Select when lowest conduction loss is critical and system-level fault handling is already implemented. |
| ON Semi NIS5132MN | 2.0A rated, 90mΩ RDS(ON), active-high enable, includes FLAG but no UVLO or soft-start; higher shutdown current (5µA). | Less robust for USB hot-plug due to missing soft-start and tighter UVLO hysteresis; suitable for simpler 5V-only systems. | Select when FLAG reporting is required but thermal margin and inrush control are secondary concerns. |
Compared with TPS22965DRLR and NIS5132MN, AP2822GKETR-G1-01 uniquely combines USB-compliant soft-start, deglitched FLAG, fold-back short protection, and sub-1µA shutdown current in SOT-23-5-making it optimal for cost-sensitive, space-constrained USB power management where integrated fault intelligence is essential.

FAQ
What is the maximum continuous current rating for AP2822GKETR-G1-01?
The AP2822GKETR-G1-01 is rated for 2.0A continuous output current, with a guaranteed current-limit threshold of 2.2A (min) to 3.2A (max) at VOUT=4.0V. This rating is fixed by the G variant designation and validated across -40°C to +85°C ambient temperature.
Does AP2822GKETR-G1-01 support reverse-current blocking?
Yes - when disabled, the device blocks reverse current flow from VOUT to VIN, with leakage limited to 0.1–1.0µA. This eliminates the need for external blocking diodes in battery-backed or multi-rail systems where backfeed could disrupt upstream supplies.
How does the FLAG output behave during over-current events?
The FLAG pin asserts low within 5–15ms of over-current detection, remains low until the fault clears and the device recovers, and is deglitched to reject transient noise. It requires an external pull-up resistor and interfaces directly with microcontroller GPIO interrupt inputs.
Is AP2822GKETR-G1-01 compatible with 3.3V logic enable signals?
Yes - the EN pin accepts logic-high signals as low as 1.6V (min), making it fully compatible with 3.3V GPIO outputs. The enable threshold is specified from 0–1.0V (low) and 1.6–5.5V (high), ensuring reliable turn-on with standard CMOS logic levels.
