Product details
Overview
AP2822HKATR-G1 from BCD Semiconductor Manufacturing Limited is a high-side power distribution switch with active-low enable, 2.0A continuous current rating, 85mΩ RDS(ON), integrated over-current and thermal protection, and open-drain FLAG output for fault reporting in USB power management systems.
For engineers reviewing the AP2822HKATR-G1 datasheet, AP2822HKATR-G1 pinout, AP2822HKATR-G1 application, or AP2822HKATR-G1 equivalent, this device supports hot-plug USB hub power control, battery-charger circuit sequencing, and notebook motherboard bus switching where precise current limiting and deglitched fault signaling are required.
Technical Context
The AP2822HKATR-G1 integrates an N-channel MOSFET with charge-pump gate drive to achieve low on-resistance while operating from 2.7V–5.5V supply. Its fold-back current limiting responds to short-circuit events by reducing output current to ~1.1A at VOUT = 0V, preventing thermal runaway.
Under-voltage lockout (UVLO) activates below 2.2V (typ.) with 0.2V hysteresis, ensuring clean startup. The deglitched FLAG output asserts low after 5–15ms delay upon over-current or over-temperature fault, compatible with standard USB controller interrupt inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85mΩ max at VIN=5.0V, IOUT=2.0A - meets USB voltage-drop requirements under full load |
| Continuous Current | 2.0A - rated for high-power USB peripheral and charger applications |
| Supply Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion and USB 5V bus operation |
| Enable Logic | Active-low EN input - simplifies direct connection to microcontroller GPIO without inversion |
| FLAG Output | Open-drain, deglitched, 5–15ms fault delay - provides noise-immune fault reporting to host controller |
| Shutdown Current | 1.0µA max - enables ultra-low-power standby in battery-powered systems |
| UVLO Threshold | 2.2V to 3.0V with 0.2V hysteresis - prevents erratic switching during brown-out conditions |
Pinout & Package
SOT-23-5 package (3.02mm × 1.80mm × 1.30mm), RoHS-compliant, green (G1 suffix), surface-mountable with standard reflow profile.
| 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 - must be low-impedance connection to system ground plane |
| 3 | EN | Active-low enable input - logic low enables switch; internal 100kΩ pull-down ensures default-off state |
| 4 | VIN | Input power rail - connects to upstream 2.7–5.5V source (e.g., USB VBUS or battery) |
| 5 | VOUT | Switched output - delivers regulated power to downstream load with soft-start ramp |
Key Features
| Feature | Design Value |
|---|---|
| No reverse current flow when disabled | Reverse leakage <1.0µA at VOUT>VVIN - prevents backfeed into upstream supply |
| Soft-start turn-on | 500µs typical rise time - limits inrush current to protect input capacitors and source |
| Fold-back short-circuit protection | Reduces short-circuit current to 1.1A (typ.) - sustains safe power dissipation during sustained faults |
| Thermal shutdown | Triggers at 150°C junction temperature with 30°C hysteresis - prevents permanent MOSFET damage |
| Output discharge resistor | 100–200Ω internal pull-low - safely discharges VOUT capacitance after disable |
Applications
| USB Bus-Powered Hubs | Hot-Plug Power Supplies |
|---|---|
|
Use Scenario: Powering downstream USB peripherals from a self-powered hub with individual port control. IC Role / Device Role / Timing Role: High-side switch enabling/disabling VBUS per port under host controller command via EN and reporting faults via FLAG. Use Value: Enables per-port over-current isolation and compliance with USB 2.0 power budgeting rules (500mA/port). |
Use Scenario: Controlled power-up of FPGA or MCU subsystems during board-level hot insertion. IC Role / Device Role / Timing Role: Sequenced power delivery with soft-start and fault monitoring to prevent supply rail collapse. Use Value: Eliminates manual reset or external sequencing ICs; FLAG signal triggers system-level error logging. |
| Notebook Motherboard USB Management | Battery-Charger Circuits |
|
Use Scenario: Isolating USB-C or legacy USB ports from main system power during sleep or fault conditions. IC Role / Device Role / Timing Role: Load switch with UVLO and thermal protection, controlled by EC (Embedded Controller) via EN. Use Value: Reduces standby current to ≤1.0µA and prevents thermal stress during adapter hot-swap events. |
Use Scenario: Enabling charging path between battery and USB input during dual-source operation. IC Role / Device Role / Timing Role: Reverse-blocking high-side switch that prevents battery discharge into faulty USB sources. Use Value: Achieves bidirectional isolation without external diodes; RDS(ON) minimizes voltage drop across charging path. |
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 TPS22965DSGR | 2.5A rating, 44mΩ RDS(ON), active-high EN, no FLAG output | Lacks fault reporting; requires external comparator for OCP detection | Preferred when lower on-resistance and higher current are critical, and fault signaling is handled externally |
| ON Semi NIS5132MN3T2G | 2.0A rating, 80mΩ RDS(ON), active-high EN, FLAG with 100ms debounce | Longer fault response time reduces responsiveness in fast-fault scenarios like ESD-induced shorts | Selected when longer flag debounce is acceptable and active-high logic simplifies control interface |
Compared with TPS22965DSGR and NIS5132MN3T2G, the AP2822HKATR-G1 uniquely combines active-low EN, deglitched FLAG with sub-15ms latency, and integrated output discharge - making it optimal for space-constrained USB host designs requiring deterministic fault handling and minimal external components.

FAQ
What is the maximum continuous current rating for AP2822HKATR-G1?
The AP2822HKATR-G1 is rated for 2.0A continuous output current at TA = 25°C with adequate PCB copper area. Derating applies above 85°C ambient; full 2.0A operation requires thermal design supporting ≤150°C junction temperature per absolute maximum ratings.
Does AP2822HKATR-G1 support reverse current blocking when disabled?
Yes. When disabled (EN high), the internal MOSFET blocks reverse current flow from VOUT to VIN, with measured reverse leakage ≤1.0µA at VOUT > VIN - eliminating need for external blocking diodes in battery backup paths.
How does the FLAG output behave during over-temperature events?
The FLAG pin goes low within 5–15ms of thermal shutdown activation at TJ ≥150°C and remains asserted until junction temperature falls below 120°C (150°C – 30°C hysteresis), providing unambiguous, latched fault indication to the host controller.
Can AP2822HKATR-G1 operate from a 3.3V supply rail?
Yes. It operates across 2.7V–5.5V, including 3.3V. At VIN = 3.3V, RDS(ON) increases to ~105mΩ (typ.), and current limit drops to ~2.5A (typ.), remaining fully functional for low-voltage USB OTG or embedded system rails.
