Product details
Overview
AP2822EKATR-G1 from Diodes Incorporated is a high-side power distribution switch with integrated N-channel MOSFET, charge pump, and protection circuitry. It delivers 1.5A continuous load current, features 85mΩ RDS(ON), operates from 2.7V to 5.5V, and includes soft-start, over-current fold-back, thermal shutdown, and UVLO - designed for USB-compliant hot-plug power management in notebook and motherboard applications.
For engineers reviewing the AP2822EKATR-G1 datasheet, AP2822EKATR-G1 pinout, AP2822EKATR-G1 application, or AP2822EKATR-G1 equivalent, key selection criteria include load current rating (1.5A), auto-discharge capability, active-high enable logic, SOT-23-5 package constraints, and FLAG fault signaling compatibility with USB host controllers.
Technical Context
The AP2822EKATR-G1 implements a charge-pump–driven N-channel MOSFET gate driver to achieve low on-resistance without requiring external bootstrap components. Its protection architecture integrates deglitched open-drain FLAG output, fold-back current limiting during short-circuit events, and thermal shutdown at +150°C with +30°C hysteresis.
It supports USB voltage-drop compliance via 85mΩ RDS(ON) at 5V input and 2A load, employs under-voltage lockout (2.5V threshold) to prevent erratic operation during brown-out, and provides 500µs typical turn-on time with controlled inrush current via internal soft-start.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85 mΩ typical at VIN = 5.0V, IOUT = 2.0A - ensures ≤212.5 mV drop at 2.5A, meeting USB 2.0 VBUS regulation margin. |
| Continuous Load Current | 1.5 A - configured by part variant (E/F series); validated across -40°C to +85°C ambient. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation from Li-ion battery (3.3V) up to USB 5V bus. |
| FLAG Response Delay | 5–15 ms - deglitched open-drain fault indicator for OCP/OTP, compatible with USB controller interrupt timing. |
| Shutdown Current | 1.0 µA max - enables ultra-low-power system standby states without external discharge circuitry. |
| Enable Logic | Active-high - EN pin threshold VENH = 1.6V min, VENL = 1.0V max; compatible with 1.8V/3.3V/5V GPIO. |
| Auto-discharge | Enabled - internal 100–200 Ω pull-low resistor discharges VOUT after shutdown, preventing backfeed in multi-rail systems. |
Pinout & Package
AP2822EKATR-G1 is housed in a RoHS-compliant, halogen-free SOT-23-5 (KE package) surface-mount package measuring 2.9 mm × 1.6 mm × 1.1 mm, with 0.95 mm lead pitch and exposed pad thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FLAG) | Fault flag output | Open-drain, active-low signal indicating OCP or OTP; requires external pull-up to host controller rail. |
| 2 (GND) | Power ground | Primary return path for switch current and internal bias; must be low-impedance connection to system ground plane. |
| 3 (EN) | Enable control input | Active-high logic input; 1.6V min high threshold allows direct interfacing with 1.8V/3.3V microcontrollers. |
| 4 (VOUT) | Switched output | Connected to load (e.g., USB port VBUS); internally discharged via 100–200 Ω resistor when disabled. |
| 5 (VIN) | Power input | Accepts 2.7–5.5V supply; feeds internal charge pump and gate driver; decoupled with ≥2.2 µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 85 mΩ ensures <213 mV drop at 2.5A, satisfying USB 2.0 VBUS tolerance (4.75–5.25V) under worst-case load. |
| Configurable load current | 1.5A continuous rating (E/F variants) with fold-back short-circuit current of 1.1A - limits power dissipation during sustained faults. |
| Integrated auto-discharge | 100–200 Ω internal pull-down on VOUT eliminates need for external discharge FET/resistor in portable USB hubs. |
| Deglitched FLAG output | 5–15 ms delay prevents false fault reporting from transient inrush or noise; simplifies host-side interrupt handling. |
| UVLO with hysteresis | 2.5V turn-on threshold with 0.2V hysteresis avoids oscillation during slow-rising input rails in battery-powered systems. |
Applications
| USB Bus-Powered Hub | Notebook USB Port Protection |
|---|---|
|
Use Scenario: Distributing 5V power from upstream USB host to four downstream ports with independent over-current detection. IC Role / Device Role / Timing Role: High-side switch per port, enabling/disabling VBUS under host software control with fault feedback via FLAG. Use Value: Prevents bus-wide shutdown during single-port overload; 1.5A rating supports BC1.2 charging while maintaining USB 2.0 signaling integrity. |
Use Scenario: Isolating USB-C or Type-A VBUS from system power during sleep or hot-unplug events. IC Role / Device Role / Timing Role: Load switch with auto-discharge, ensuring VOUT drops below 0.4V within 10ms of disable to meet USB suspend timing. Use Value: Eliminates need for discrete discharge circuitry; 1µA shutdown current extends battery life in always-on USB accessory detection. |
| Hot-Plug PCIe Card Power Sequencing | USB Self-Powered Docking Station |
|
Use Scenario: Controlling 5V auxiliary power to M.2 or mini-PCIe modules during insertion/removal. IC Role / Device Role / Timing Role: Hot-swap controller with soft-start and fold-back protection, synchronized to PCIe reset assertion. Use Value: Limits inrush to <1.5A peak, avoiding host power rail sag; FLAG signals fault to BMC before PCIe link training begins. |
Use Scenario: Managing power delivery to multiple peripherals (HDMI, Ethernet, storage) from a single USB-C PD input. IC Role / Device Role / Timing Role: Secondary-side distribution switch for legacy 5V rails, coordinated with PD controller via EN/FLAG handshake. Use Value: Enables independent port-level reset without re-negotiating PD contract; 85mΩ RDS(ON) minimizes heat rise in compact dock enclosures. |

FAQ
What is the maximum continuous current rating for AP2822EKATR-G1?
The AP2822EKATR-G1 is rated for 1.5A continuous output current at TA = +25°C, derating to ~1.1A at +85°C ambient. This rating is validated with 2.2µF input capacitance and proper PCB copper area for thermal dissipation. The device enters fold-back current limiting if VOUT shorts to GND, reducing short-circuit current to 1.1A to limit junction temperature rise.
Does AP2822EKATR-G1 include auto-discharge functionality?
Yes - AP2822EKATR-G1 includes an internal 100–200 Ω pull-down resistor on the VOUT pin that activates upon shutdown, discharging the output capacitance to <0.4V within 10ms. This meets USB suspend timing requirements and prevents backfeed into upstream sources, eliminating need for external discharge components.
How does the FLAG pin behave during over-current events?
The FLAG pin asserts low within 5–15ms of over-current detection, with built-in deglitching to reject sub-millisecond transients. It remains latched low until EN is cycled or VIN drops below UVLO threshold. The open-drain structure requires an external pull-up resistor (typically 10kΩ to 3.3V) to interface with USB host controller GPIO interrupts.
Is AP2822EKATR-G1 recommended for new designs?
No - Diodes Incorporated marks AP2822EKATR-G1 as "NOT RECOMMENDED FOR NEW DESIGN" with no alternate part provided. It remains available for legacy support and existing production, but designers should consult Diodes' latest high-side switch portfolio (e.g., AP2823 series) for roadmap-aligned alternatives with enhanced features and extended lifecycle.
