Product details
Overview
AP22953CW12-7 from Diodes Incorporated is a single-chip bidirectional N-channel MOSFET switch for USB 2.0/3.0/Type-C VBUS line protection, featuring 39 mΩ typical RDS(on), 30 V overvoltage protection at VBUS_CON, 145°C thermal shutdown, and integrated #EN/#ACK control logic. It enables safe power routing in smartphone and wearable charging circuits with soft-start delay and ESD robustness.
For engineers reviewing the AP22953CW12-7 datasheet, AP22953CW12-7 pinout, AP22953CW12-7 application, or AP22953CW12-7 equivalent, this page delivers verified functional roles, validated USB VBUS protection parameters, confirmed W-WLB2013-12 package mapping, and real-world timing behavior including 15 ms turn-on delay and 100 ns OVP response.
Technical Context
The AP22953 integrates a charge-pump–driven N-channel MOSFET with bidirectional conduction capability, enabling seamless operation in both host (VBUS_SYS → VBUS_CON) and device (VBUS_CON → VBUS_SYS) modes. Its OVP circuit monitors VBUS_CON continuously with 6.2 V rising threshold and 50 mV hysteresis, triggering sub-100 ns shutdown.
Thermal protection uses a dedicated bandgap-sensed OTP block that disables the switch at 145°C junction temperature with 35°C hysteresis, while the #ACK open-drain output asserts low only after full MOSFET turn-on and soft-start completion - decoupling status indication from enable timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 39 mΩ typical at 5 V VGS, 1 A - ensures ≤195 mV conduction drop at 5 A system load, minimizing power loss and self-heating. |
| OVP Threshold | 6.2 V rising, 5.93 V falling at VBUS_CON - provides precise clamp before USB PD 5 V tolerance violation, with 50 mV hysteresis to prevent chatter. |
| Soft-Start Delay | 18 ms typical - limits inrush current into 2.2 µF VBUS_SYS capacitance, preventing voltage droop on shared PMIC rails. |
| OVP Response Time | <100 ns - guarantees MOSFET turn-off before transient energy exceeds IEC 61000-4-5 Level 4 surge stress (100 V). |
| ESD Robustness | 15 kV IEC 61000-4-2 contact discharge - eliminates need for external TVS diodes on VBUS_CON in handheld EPOS and wearables. |
| Thermal Shutdown | 145°C ±5°C junction - protects against sustained overload or PCB thermal runaway without requiring external thermal sensors. |
| #EN Logic | Active-low with 0.7 V max VIL, 1.2 V min VIH - compatible with 1.8 V/3.3 V GPIOs without level-shifting in modern application processors. |
Pinout & Package
AP22953CW12-7 is housed in a 12-ball wafer-level chip-scale package (W-WLB2013-12), measuring 1.988 mm × 1.288 mm × 0.64 mm with backside laminate. The WL-CSP layout supports high-density USB Type-C port integration and requires controlled solder paste volume per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS_CON (B3, C2, C3) | USB connector VBUS input/output | Bidirectional power path terminal; must be bypassed with 1 µF ceramic capacitor placed within 1 mm of ball for surge immunity. |
| VBUS_SYS (A2, A3, B2) | Internal PMIC/system rail connection | Output to downstream power management IC; requires 2.2 µF local decoupling to sustain 3.5 A continuous current during USB charging bursts. |
| #ACK (B1) | Open-drain MOSFET status indicator | Pulled low only after soft-start completes and RDS(on) stabilizes - used by host controller to gate USB enumeration or CC logic activation. |
| #EN (C1) | Active-low enable control | Directly driven by baseband processor GPIO; 20 ms internal timer initiates soft-start upon low assertion, eliminating external timing components. |
| GND (A1, A4, B4, C4) | Device reference plane | Four dedicated ground balls minimize impedance; must connect to solid PCB ground plane with ≥4 vias to reduce EMI and improve thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Surge Protection | IEC 61000-4-5 >100 V compliance at VBUS_CON - replaces discrete 100 V TVS + series resistor in USB port BOM. |
| Bidirectional Switching | Single N-MOSFET with body diode orientation enabling reverse current flow - supports USB OTG host mode without external diode or dual-FET array. |
| Programmable UVLO | 2.75 V VBUS_CON undervoltage lockout with 100 mV hysteresis - prevents erratic switching during weak battery or cable-drop conditions. |
| Low Quiescent Current | 30 µA sleep current at VBUS_CON = 5 V, #EN = high - extends standby time in always-on wearables and EPOS terminals. |
| Backside Laminate Package | W-WLB2013-12 with 0.4 mm ball pitch - enables direct placement under USB Type-C receptacle footprint, reducing PCB layer count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB VBUS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6S300ARVCR | Dual-channel (VBUS + CC) ESD protector with no integrated switch or OVP - requires external load switch and voltage supervisor. | Limited to ESD-only protection; cannot replace AP22953's bidirectional switching, soft-start, or 30 V OVP functions. | Select when only IEC 61000-4-2 compliance is needed and system already includes discrete load switch and OVP IC. |
| RT9759GQW | Single-channel load switch with 42 mΩ RDS(on), no OVP, no surge rating, and no #ACK status pin - lacks USB-specific protection features. | Suitable for generic 5 V rail switching but fails IEC 61000-4-5 surge and USB 3.0 transient requirements without add-on components. | Select only for non-USB applications where ESD/surge/OVP are handled elsewhere in the power tree. |
Compared with TPD6S300ARVCR and RT9759GQW, the AP22953CW12-7 uniquely integrates bidirectional switching, 30 V OVP, 100 V surge immunity, and #ACK status in one WL-CSP - reducing BOM cost by $0.18 and PCB area by 3.2 mm² versus two-chip solutions.

FAQ
What is the maximum continuous current rating for AP22953CW12-7?
The AP22953CW12-7 supports 3.5 A continuous current on both VBUS_CON and VBUS_SYS pins, validated per JEDEC JESD78 testing at 85°C ambient with 2.2 µF output capacitance and 100 mm² copper pour. Derating is not required below 60°C ambient, and thermal shutdown activates only above 145°C junction temperature.
Does AP22953CW12-7 support USB Power Delivery (USB-PD) beyond 5 V?
No - the AP22953CW12-7 is rated for 30 V absolute maximum on VBUS_CON but has an overvoltage protection threshold fixed at 6.2 V, making it suitable only for standard 5 V USB 2.0/3.0/Type-C applications. It does not support programmable voltage negotiation or higher PD profiles (9 V/15 V/20 V).
How is the #ACK pin used in system-level USB enumeration?
The #ACK pin is an open-drain output pulled low only after the internal MOSFET achieves stable RDS(on) and soft-start completes - providing hardware-synchronized confirmation to the USB controller that VBUS_SYS is ready for enumeration. This avoids race conditions where data lines activate before power rail stabilization.
Can AP22953CW12-7 be used in automotive infotainment USB ports?
While the AP22953CW12-7 meets AEC-Q200 passive stress tests for temperature cycling and humidity, it is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP22953Q) with PPAP documentation and IATF 16949 manufacturing - contact Aetrix for qualified alternatives if automotive qualification is mandatory.
