Lithium Battery

Case of electric razor

This scheme adopts pl51t / a003 chip, which integrates 16kb flash, 256byte true EEPROM, 11bit ADC, 6-channel PWM and other rich resources; The scheme software realizes nickel chromium lithium battery charging management, overshoot and discharge protection; Abnormal anti burning machine functions such as motor drive and motor jamming; Interview dynamic display, use time, remaining power evaluation and other functions.

1、 Application scheme features

1. The main control chip pl51t / a003 has rich resources and high integration;

2. 11bit ADC module, integrating battery charge and discharge protection and remaining available power evaluation;

3. Motor working current detection, real-time detection of overload current;

4. There are many IO resources to achieve a variety of screen display effects and dynamically update the usage and remaining power;

5. 16kb flash program space, which can optimize various battery management algorithms.
