Product details
Overview
The IW662-08-SO8 from Renesas Electronics is a secondary-side AC/DC combo controller integrating Qualcomm® Quick Charge™ 3.0 interface, XM-Comm digital communication, and synchronous rectification control. It supports VBUS output from 3.6V to 9V in 200mV steps, delivers <20mW no-load power, and operates with iW1796-08 primary-side controllers in flyback adapters for smartphones and tablets.
For engineers reviewing the IW662-08-SO8 datasheet, IW662-08-SO8 pinout, IW662-08-SO8 application, or IW662-08-SO8 equivalent, key selection criteria include QC3.0 HVDCP compliance (3.6–9V range), D+/D− over-voltage protection, lossless VDS sensing for SR timing, 8-lead SOIC package compatibility, and optocoupler-free operation via XM-Comm.
Technical Context
The IW662-08-SO8 implements Dialog's proprietary XM-Comm protocol to transmit voltage requests, current limits, OVP/UV signals, and fault resets across the transformer-eliminating the optocoupler when paired with iW1796-08. Its digital adaptive turn-off control minimizes SR MOSFET deadtime without requiring external Schottky diodes.
This device functions as both a USB BC1.2/QC2.0/QC3.0 interface controller and an advanced SR driver with integrated gate drive (±3A peak), high-voltage drain sensing up to 100V, and programmable fast discharge from high voltage to 5V upon MD unplug or level change.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBUS Range | 3.6V to 9V in 200mV increments - enables precise QC3.0 voltage negotiation while disabling 10–12V levels per custom option. |
| No-Load Power | <20mW - achieved via intelligent low-power mode and optimized LDO/PLR biasing for Energy Star and EU CoC Tier 2 compliance. |
| DRAIN Pin Voltage | –1.5V to 100V - supports high-voltage flyback secondaries without external clamping circuits. |
| Gate Peak Current | ±3A - drives external SR MOSFETs with fast edge rates and robust turn-on/turn-off control. |
| ESD Rating (D+/D–) | ±6,000V HBM - ensures robustness against USB port electrostatic events during plug/unplug cycles. |
| Operating Voltage (VIN) | 3V to 16V - powers internal LDO and VBUS sensing circuitry directly from adapter output rail. |
| Package | 8-Lead SOIC - industry-standard footprint compatible with automated assembly and thermal management in compact adapters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secondary-side rapid charge and synchronous rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| iW662-05-SO8 | Identical architecture and pinout; differs only in primary-side pairing (iW1790-08 vs. iW1796-08) and OVP threshold calibration. | Optimized for iW1790-based designs; lacks iW1796's enhanced fault response for soft shorts. | Select when using iW1790-08 primary controller and requiring identical 3.6–9V VBUS range and 0.422 kCC coefficient. |
| iW662-02-SO8 | Same SOIC-8 package and core functionality; supports 3.6–12V VBUS (not limited to 9V) and uses iW1796-09 primary controller. | Enables full QC3.0 12V compliance but requires updated OVP calibration and fails QC2.0 HVDCP test per Note 3. | Choose for designs needing 12V capability and higher constant-power range (6.2–12V), accepting trade-offs in QC2.0 backward compatibility. |
Compared with IW662-05-SO8 and IW662-02-SO8, the IW662-08-SO8 uniquely pairs with iW1796-08 to deliver <20mW no-load power and optimized D+/D− OVP for 3.6–9V-only applications-making it ideal for cost-sensitive, QC3.0-focused smartphone adapters where 12V is unnecessary.

FAQ
What is the VBUS output range supported by the IW662-08-SO8?
The IW662-08-SO8 supports a VBUS output range of 3.6V to 9V in 200mV increments. This is a customized variant that disables 10V–12V levels, ensuring compliance with QC3.0 negotiation while optimizing for smartphone use cases where higher voltages are unnecessary. The IW662-08-SO8 achieves this via factory-trimmed kCC coefficient (0.422) and OVP calibration matched to iW1796-08.
Does the IW662-08-SO8 require an optocoupler when used with a primary-side controller?
No, the IW662-08-SO8 eliminates the optocoupler when paired with the iW1796-08 primary-side controller. It uses Dialog's XM-Comm digital communication technology to transmit voltage requests, current limits, fault signals, and reset commands across the power transformer-reducing BOM cost, improving reliability, and simplifying PCB layout compared to traditional optocoupler-based feedback systems.
How does the IW662-08-SO8 implement D+/D− over-voltage protection?
The IW662-08-SO8 integrates proprietary secondary-side D+/D− over-voltage protection (OVP) that monitors VBUS-to-data-line voltage differentials. Upon detecting a soft short (e.g., damaged cable causing D+ or D− to rise toward VBUS), it triggers immediate shutdown and fault reporting via XM-Comm-preventing thermal runaway and enabling safe recovery without latching.
What is the purpose of the DIS pin on the IW662-08-SO8?
The DIS pin on the IW662-08-SO8 controls active fast discharge of the output capacitor. When a mobile device is unplugged or requests a lower voltage level, the IW662-08-SO8 asserts DIS to drive an external switch (or internal FET) and rapidly discharge VBUS from high voltage (e.g., 9V) down to 5V-meeting USB BC1.2 and QC3.0 safety timing requirements and preventing residual voltage hazards.
Is the IW662-08-SO8 backward compatible with older charging standards?
Yes, the IW662-08-SO8 is fully backward compatible with Qualcomm Quick Charge 2.0 and USB Battery Charging Specification Revision 1.2. It automatically negotiates 5V output for non-QC devices and supports HVDCP handshake sequences for QC2.0, enabling single-design reuse across legacy and next-generation mobile devices without firmware changes.
