Introduction
Personal care products like electric
toothbrushes and electric shavers have gained significant popularity as people seek
convenient and efficient methods to enhance daily hygiene routines.
Compared to traditional manual
toothbrushes, electric toothbrushes with vibrating brush heads powered by motors can
provide improved oral care experience by reaching areas that are often missed by
manual brushing. Electric toothbrushes also provide better brushing techniques such
as maintaining the recommended brushing time and applying appropriate pressure.
Likewise, electric shavers utilizing
rotating blades powered by motors have revolutionized the shaving experience,
offering comfortable, safe, and precise grooming results.
Both devices need MCU integrated to
enable precise motor control, sensing, power management and user interface
functions. Now, TI’s low-cost MSPM0 MCUs with high-performance and small size can be
leveraged to empower small but powerful electrical toothbrushes and electrical
shavers!
Why is MSPM0 an Excellent Choice
for Electric Toothbrushes and Electric Shavers?
TI's MSPM0Cx MCUs featuring Arm®
Cortex®-M0+ core with 24 MHz
CPU, 32-bit structure, 4 to 16 KB Flash provide cost-effective designs for electric
toothbrush and shaver applications.

three flexible timers, containing one advanced with complementary outputs and
dead-band
- Integrated analog: 10-bit,
10ch ADC with 1 Msps sampling rate
- Adequate interfaces:
Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C) and Universal
Asynchronous Receiver/Transmitter (UART)
- Low power consumption:
excellent power consumption performance in both run mode and standby mode
- Low cost: Low-cost Arm
Cortex-M0+ MCU featured with in-system programmable flash
- Small package size: seven
package options, the smallest no-lead 8-pin WSON with 2.0 x 2.0 mm2 size and
smallest leaded 8-pin SOT with 2.8 x 2.9 mm2 size.
- GPIO: Up to 6 IO in 8-pin
packages and 18 general-purpose input/output (GPIO) in 20-pin packages
What Can MSPM0 do in Electric
Toothbrushes and Electric Shavers?
