Lint Remover PCBA Control Board Solution

I. Solution Overview

II. Core Functional Design

1. Charging Management Module

   5V USB charging input with comprehensive lithium battery safeguards against overcharge, overdischarge, overcurrent and short circuit. LED indicators show ongoing charging and fully charged status for safe 3.7V lithium battery power supply.

2. Motor Drive & Speed Control

   DC motor driver supports single-speed or dual-speed modes (gentle / powerful cut) with one-key power switch. Smooth motor startup minimizes vibration and noise for efficient trimming without damaging fabric.

3. Battery Indication & Low-Battery Alert

   Real-time LED remaining power display; automatic speed reduction or power cutoff at low voltage to prevent battery and motor damage from deep discharge.

4. Safety Protection Design

   Blade cover open stop protection and accidental power-on lock avoid unintended startup. Ultra-low standby power design extends runtime per full charge.

5. Optional Customized Upgrades

   Optional Type-C regular/fast charging, auto power-off timer, blue light sterilization, suction adjustment, touch keys and waterproof circuitry.
