Description
This TI Design uses Texas Instruments’ low-voltage H-Bridge motor driver with an integrated 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 to 5.5 V
- Delivers 5 A continuous and 8 A peak-drive current
- Small PCB form factor of 43.2 x 14.6 mm
- Low component count to reduce cost
- Less than 50 nA Battery Leakage Current When Off
