Solid State Systems Sss6698-bb Instant

Solid State Systems (SSS) SSS6698-BB is a high-performance USB 2.0 flash memory controller primarily used in mid-range consumer drives like the Kingston DataTraveler 2.0 and various Toshiba TransMemory Technical Overview Developed by Solid State System Co., Ltd. (3S)

Typical applications and example circuits

• Synchronous buck converters (as high-side/low-side pair).
• H-bridges for BLDC/brush DC motor drivers.
• DC contactor replacements / high-current solid-state switches.
• Synchronous rectifiers in power supplies.

5. Common Issues & Fixes

a) Drive not detected or “0 MB”

• Cause: Firmware corruption, NAND bad blocks, or power surge.
• Fix: Short two specific test points (TP) on the PCB to force ROM mode, then reflash.

• Silent, contactless switching: no arcing or mechanical bounce — great for long-life, high-cycle applications.
• Fast switching: much faster than mechanical relays, useful for PWM or precise control.
• Durability: solid-state design reduces maintenance and extends lifespan in vibration or dusty environments.
• Compact footprint: easy to integrate into dense control panels or small enclosures.
• Low control power: can be driven directly from microcontrollers or PLC outputs in many cases.
