Hair & Beard Trimmer Electronics — Model Family
engineered end-to-end.
IDEAS designed the control electronics for a family of cordless hair and beard trimmers — four models, from a simple entry-level board to premium versions with a digital display. Each board fits the slim handle of the trimmer and handles motor drive, battery charging and user control, while sharing a common design approach so new models can be derived quickly and cost-effectively.
Low-cost microcontroller · DC motor drive · Li-ion charging and protection · LED / segment battery display · single-button control · compact slim-line PCBs
KEY FEATURES
What it does.
- Four trimmer models from one common design platform
- Slim, shaped PCBs that fit narrow trimmer handles
- Efficient DC motor drive with soft start for smooth, quiet cutting
- Li-ion charging with over-charge, over-discharge and over-current protection
- Battery level shown as a percentage on 3-digit LED displays (premium models)
- Status icons for charging, travel lock and maintenance / cleaning reminders
- Single push-button on / off with travel lock to prevent accidental switch-on
- Low standby current for long shelf life
- Designed for low-cost, high-volume manufacturing
