Yutai ETA9030 headphone charging compartment super fast charging chip introduction

With the TWS brand concentration, functional diversification, high quality, high performance requirements, for high-end users, Yutai ETA9030 can achieve higher efficiency of charging and discharging conversion, support two-way independent communication, independent warehouse detection, headphone super fast charging, one-key clearing, one-key pairing, low-power alarm, a variety of lamps and breathing lights and Hall and other application scenarios, can match all the mainstream Bluetooth masters on the market, Yutai is equipped with a professional team to assist customer development, greatly shortening the development cycle.

Yutai ETA9030 has the following features:

High withstand voltage, high precision

In terms of circuits, the ETA9030 has a high withstand voltage of 28V, high-precision charging, cutoff current (within +-6%), and a standby power consumption of only 3uA. The circuit is more secure and reliable.

With self-discharge NTC protection, the charging temperature is low

When charging, the discharge temperature using the switch charge is lower, and the high-precision output limit is supported, which can meet the 62368 certification. Discharge current as low as 1mA cutoff for headphone small capacity battery applications. ETA9030 comes with self-charge, discharge NTC protection, charging state to meet the Jeita specification, the battery is safer while streamlining the circuit board circuit, only need 4 capacitors + NTC resistance to achieve low temperature fast charging of headphones.

Built-in I2C interface, support super fast charging and a variety of functions

ETA9030 built-in flexible I2C interface can meet different customer customization needs, support the fastest 115200 communication rate of dual-channel independent two-way communication, so that communication without delay. Support binaural independent detection, as low as 1uA into the position, out of the warehouse wake-up. Support headphone super fast charging 3.6-5.1V following, charging conversion efficiency is higher, charging speed is faster.

With the TWS brand concentration, functional diversification, high quality, high performance requirements, for high-end users, Yutai ETA9030 can realize charging, discharge conversion efficiency is higher, support two-way independent communication, independent out, warehouse detection, headphone super fast charge, one key clear, one key pairing, low battery alarm, a variety of lamps and breathing lights and Hall and other application scenarios, can match all the mainstream Bluetooth master control on the market, Yutai is equipped with a professional team to assist customers in development, greatly shortening the development cycle.
