In the design of smart keyboards, response speed and energy efficiency are the core of user experience. For AI-driven keyboards (such as high-end products equipped with DeepSeek chips), VBsemi 's VBGQT1102 shielded gate trench MOSFET (SGT) has become a key component for improving interaction fluency with its ultra-low loss and nanosecond switching speed.

 Why choose VBGQT1102?

1. Extremely low conduction loss and stable power supply

The on-resistance is less than 10mΩ@4.5V, which greatly reduces the voltage drop in the keyboard power supply path and prevents the stability of the DeepSeek chip from being affected by voltage fluctuations in the 5V/12V system.

Compared with traditional MOSFET, power consumption is reduced by more than 30%, significantly extending the battery life of the wireless keyboard.

2. SGT technology: the ultimate solution for high-frequency switching

The shielded gate trench structure reduces Miller capacitance and gate charge, and the switching delay reaches nanoseconds, perfectly matching the needs of high-frequency key scanning.

Actual tests show that VBGQT1102 can shorten the overall delay from key signal to AI response by 15%, achieving "zero-sense delay" input.

3. Compact design, strong compatibility

The DFN/SOP-8 package saves PCB space and is suitable for compact keyboard layouts.

Supports 3.3V/5V MCU direct drive, without complex peripheral circuits, lowering the design threshold.

Gain effect of DeepSeek interface

Lossless signal transmission: The low internal resistance characteristic ensures that the AI command parsing link is distortion-free, improving the accuracy of voice recognition and intelligent feedback.

Low temperature and long battery life: The low heat generation due to improved efficiency is especially suitable for long-term working scenarios of wireless keyboards.

High reliability: It has passed batch verification of fast charging and IoT devices, with an MTBF (mean time between failures) of over 500,000 hours.
