Electric Toothbrush Controller Reference Design
TIDA-00602
Overview
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 V
- Delivers 5-A continuous and 8-A peak-drive current
- Small PCB form factor of 43.2 mm x 14.6 mm
- Low-component count to reduce cost
- Less than 50-nA battery leakage current when off
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
