Electric Toothbrush Controller Reference Design
Description
This reference design uses our low-voltage H-Bridge motor driver with an integrated low dropout (LDO) voltage regulator and an ultra-low-power microcontroller (MCU) to demonstrate a full implementation of a battery-powered electric toothbrush.
Features
- Battery voltage ranging from 2 V to 5.5 VDelivers 5-A continuous and 8-A peak-drive currentSmall PCB form factor of 43.2 mm x 14.6 mmLow-component count to reduce costLess than 50-nA battery leakage current when off
Applications
- Process analytics
- Electronic thermometer
- Fitness machine
- Beauty & grooming
- Electric toothbrush
- Clinical digital thermometer
- Digital stethoscope
