Product details
Overview
AP2822AKATR-G1 from BCD Semiconductor Manufacturing Limited is a 0.5A continuous-rated high-side power distribution switch in SOT-23-5 package, featuring 85mΩ RDS(ON), active-high enable logic, 2.7–5.5V operating range, and integrated over-current, thermal, and short-circuit protection with deglitched open-drain FLAG output. It serves as a USB-compliant hot-swap power controller for downstream bus-powered peripherals.
For engineers reviewing the AP2822AKATR-G1 datasheet, AP2822AKATR-G1 pinout, AP2822AKATR-G1 application, or AP2822AKATR-G1 equivalent, key selection criteria include current rating (0.5A), enable polarity (active-high), fault reporting via FLAG, soft-start behavior, and compliance with USB voltage-drop requirements under load.
Technical Context
The AP2822AKATR-G1 integrates an N-channel MOSFET with charge-pump gate drive to achieve low on-resistance while operating from a single 2.7–5.5V supply. Its internal UVLO ensures turn-on only above 2.2–3.0V, and thermal shutdown activates at 150°C with 30°C hysteresis.
Current limiting is fixed at 0.7–1.4A (typ. 1.0A) depending on VOUT and temperature; fold-back short-circuit current is 0.7A. The deglitched FLAG output asserts low after 5–15ms delay upon OCP/OTP detection, requiring external pull-up for USB controller interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 85 mΩ max at 5V VIN, 2A load - meets USB 5V drop spec under full 0.5A load |
| Continuous Current | 0.5A - rated for sustained operation without derating at TA ≤ 85°C |
| Enable Polarity | Active-high - EN pin asserts high ≥1.6V to enable switch; low ≤1.0V disables |
| FLAG Output | Open-drain, active-low - signals OCP/OTP faults with 5–15ms delay; requires external pull-up |
| Supply Current | 68 µA typ - enables low-power USB suspend mode without significant system leakage |
| Shutdown Current | 1.0 µA max - ensures minimal battery drain when disabled in portable applications |
| UVLO Threshold | 2.2–3.0V rising - prevents erratic switching during brown-out or cold-start conditions |
Pinout & Package
SOT-23-5 package: 2.82 × 2.82 × 1.30 mm body, 0.95 mm lead pitch, gull-wing leads, RoHS-compliant "G1" green finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | FLAG | Open-drain fault indicator - sinks current when OCP/OTP occurs; requires external pull-up to host controller rail |
| 2 | GND | Power ground reference - must be low-impedance connection to minimize sensing error and thermal rise |
| 3 | EN | Logic-level enable input - high ≥1.6V enables switch; low ≤1.0V forces shutdown and discharge path activation |
| 4 | VIN | Main power input - accepts 2.7–5.5V; connects to upstream USB VBUS or regulated 3.3/5V rail |
| 5 | VOUT | Switched output - delivers protected power to downstream load; includes reverse-current blocking when disabled |
Key Features
| Feature | Design Value |
|---|---|
| Soft-start control | 500 µs typical turn-on time - limits inrush current to prevent VBUS droop during hot-plug events |
| Load short protection | Fold-back current limit at 0.7A - reduces power dissipation during sustained short-circuit conditions |
| No reverse current flow | Active blocking when disabled - eliminates backfeed from VOUT to VIN, critical for multi-rail USB hubs |
| Output shutdown pull-low | Integrated 100–200 Ω discharge resistor - ensures rapid VOUT decay after disable, meeting USB detach timing |
| Thermal shutdown hysteresis | 30°C - prevents oscillation near trip point; recovery occurs at ~120°C after cooldown |
Applications
| USB Bus-Powered Hub | Hot-Plug Peripheral Port |
|---|---|
|
Use Scenario: Powering downstream ports on a self-powered USB 2.0 hub where each port requires independent over-current protection and hot-swap capability. IC Role / Device Role / Timing Role: High-side switch controlling VBUS delivery per port; FLAG signals fault to hub controller for port disable. Use Value: Enables individual port current limiting (0.5A), prevents bus-wide shutdown, and supports USB specification-compliant attach/detach sequences. |
Use Scenario: Adding hot-plug power control to a notebook docking station's USB-C accessory port with legacy USB-A support. IC Role / Device Role / Timing Role: Isolates accessory VBUS rail; soft-start and FLAG ensure clean insertion without system reset or controller lockup. Use Value: Eliminates need for discrete MOSFET + protection IC; 500 µs tON and deglitched FLAG meet USB 2.0 enumeration timing budgets. |
| Battery-Charger Load Switch | Notebook System Power Rail |
|
Use Scenario: Enabling/disabling charging current path from a USB PD source to a Li-ion battery management IC during charge state transitions. IC Role / Device Role / Timing Role: High-side switch inserted between PD converter output and charger input; FLAG alerts MCU of over-current during pre-charge phase. Use Value: Provides precise 0.5A current ceiling and thermal margin during constant-current charge; reverse-current blocking prevents battery backfeed. |
Use Scenario: Distributing standby power to USB controller, EC, and keyboard interface on a motherboard's 3.3V auxiliary rail. IC Role / Device Role / Timing Role: Always-on power switch with active-high enable tied to chipset power-good signal; FLAG monitors for accidental shorts. Use Value: Replaces discrete solution with integrated protection, reducing BOM count and PCB area while maintaining <1µA shutdown current for low-power states. |
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 |
|---|---|---|---|
| Texas Instruments TPS22915YZPR | 0.5A rating, 85mΩ RDS(ON), active-high enable, but no FLAG output or fold-back short protection | Lacks fault reporting and short-circuit fold-back - requires external monitoring circuitry for USB compliance | Select when FLAG signaling is unnecessary and board space allows discrete OCP implementation |
| ON Semiconductor NIS5132MN3T1G | 0.5A rating, 100mΩ RDS(ON), active-high enable, includes FLAG but no UVLO or soft-start | Higher RDS(ON) increases voltage drop; missing UVLO risks unstable startup below 2.7V | Prefer only in non-USB applications where 100mΩ drop is acceptable and input voltage is tightly regulated |
Compared with TPS22915YZPR and NIS5132MN3T1G, the AP2822AKATR-G1 uniquely combines USB-compliant RDS(ON), integrated FLAG with deglitching, fold-back short protection, and soft-start in a single SOT-23-5 device - eliminating external components required by alternatives for full USB 2.0 power delivery compliance.

FAQ
What is the maximum continuous current rating for AP2822AKATR-G1?
The AP2822AKATR-G1 is rated for 0.5A continuous output current at ambient temperatures up to +85°C with adequate PCB copper area. Its current-limit threshold is specified at 0.7–1.4A (typ. 1.0A) under VOUT = 4.0V, providing headroom for transient surges while maintaining safe SOA operation.
Does AP2822AKATR-G1 support reverse-current blocking?
Yes - the AP2822AKATR-G1 blocks reverse current flow from VOUT to VIN when disabled, with leakage less than 1.0 µA. This is achieved through internal MOSFET gate control and is confirmed in Electrical Characteristics (Table 9, IREVERSE parameter), making it suitable for multi-rail USB hubs and battery-isolation applications.
How does the FLAG output behave during over-current events?
The FLAG pin asserts low within 5–15ms after over-current detection, with deglitching to reject sub-millisecond transients. It remains low until the fault condition clears and the device recovers from current-limit or thermal shutdown. External pull-up is mandatory, as FLAG is open-drain and has no internal pull-up.
Can AP2822AKATR-G1 operate from a 3.3V supply?
Yes - the AP2822AKATR-G1 operates across 2.7V to 5.5V, including 3.3V nominal rails. At 3.3V input, RDS(ON) increases slightly (per Figure 6), but remains within USB voltage-drop limits for 0.5A loads. UVLO still functions, with turn-on occurring at ≥2.2V, ensuring robust startup from partially discharged sources.
