5 V booster charge 8.4 V chip

2V to charge 8.4V lithium battery, you need to convert the 5V input of the USB port to 8.4V to charge the two strings of batteries.The HU6281 boost current limiting IC can be used to directly supply power to the 8.4V boost, which is cost-optimized.Below is the circuit diagram.If you don't need a charging management circuit, just a boost IC, that is, the 6-pin HU6281 can input a 5V boost 8.4V 700MA boost 8.4V lithium battery circuit.

5V boost 8.4V special charging IC for charging lithium battery, in product design and chip application, the circuit of lithium battery is inseparable from three basic circuits to control lithiumBattery charging and discharging.The HU5810A integrated with 5V boost 8.4V circuit and charging management circuit supports constant current trickle current limiting charging, red light and full green light, Note: The maximum power of this product can reach 10w, and the applicable applications are: 5V/2A, 8.4V/chargingCurrent up to 1A

3. The above two currents of HU6281 (8.4V/500mA) and HU5810A (8.4V/1A) are both small, the following recommends a 5V literVoltage charging 8.4V chip, the maximum charging current can reach 4A at 8.4V

, the power up to 35W is very cost-effective, and can provide beta verification
