ETA9640 + Bluetooth headset TWS charging case + wireless charging receiver IC1 1. A chip meets all the functions of mobile power, a simpler periphery, and less BOM cost. 2. Integrated power display, etc., originally relied on MCU implementation. 3. No need for lithium-ion protection ICs and any active devices such as MOSFETs, greatly simplifying mobile power supply design. 4. There is no output short-circuit lock problem. 5.2A charge and discharge, 1A boost efficiency 90%, 1 to 2.2uH inductance. 6. Boost discharge: 5V/1A synchronous boost, efficiency up to 90%; 2MHz switching frequency, inductor miniaturization, small output ripple. 7. No need to switch, boost is always on: no-load standby power consumption 100uA (excluding USB interface divider resistor power consumption). 8. Charging function: 1A linear charging with input overvoltage protection. 9. Power display function: Original single LED, “heartbeat” mode displays LED power, and power consumption reduces energy consumption by 80%. 10. Lithium battery protection function: overcharge, over discharge, output short circuit protection, short circuit self-recovery, short-circuit protection at the charging input terminal. #wirelesschargingsolutions #wirelessmodule #wirelesschargingbase https://www.instagram.com/p/Bws532IABqo/?utm_source=ig_tumblr_share&igshid=uknxb559fdjg
