Here is a simple USB powered lamp that can be used to light your desktop during power failures. The circuit operates from the 5 Volt available from the USB port. The 5V from the USB port is passed through current limiting resistor R2 and transistor Q1. The base of transistor Q1 is grounded via R1 which provides a constant bias voltage for Q1 together with D2. The diode D1 prevents the reverse flow of current from battery. C1 is used as a noise filter. Two white LED’s are used here for the lamp, you can also use a 2 V torch bulb instead of LED’s. LED D3 indicates connection with USB port.
This project is a TP5410-based Battery Management System (BMS) circuit. The TP5410 IC handles battery charging, voltage regulation, and protection. It uses various capacitor, resistor, and diode components along with LEDs for status indication, making it an ideal solution for portable electronic devices. #project #Template #charger #reusable #module #batterycharger #template #bms #TP5410 #topPowerASIC #toppower #toppowerasic
