In order to face the demands of harsh low-power standby and resisting high-voltage shocks, Yutai Semiconductorhas launched ETA9084/ETA9085 new charging and discharging three-in-one Bluetoothcharging The warehouse solution adopts ESOP8, ESOP10, and DFN2*3 three packages, which are compatiblewith the requirements of most placement machines, and the smaller package reduces space constraints. The chipcontinues to be upgraded on the original 9697, continuing the previous traditional "low power consumption" design, with four-light display at the same time. To meet the application requirements of the market, save the cost of MCU for customers, simple peripheral circuits, and greatly reduce the development cycle.

With ultra-high reliability and the ultimate experience. It integrates 5V standby power consumption with power consumption less than 10μA in an ultra-small package, and also integrates charging with a maximum voltage of 20V, which greatly enhances the ultra-long standby time of the Bluetooth headset charging box and resists various uncertain input shocks. ability.

ETA9084/ETA9085 has a built-in high-performance linear charger with a voltage of up to 20V, which can resistthe impact of various uncertain factors of household or car chargers, completely avoid the problem of product damage on the consumer side, supplemented by the charging dual light indicator function , Four-lamp power indicator, NTC temperature monitor, programmable charging current, and the charging cut-off voltage and precise charging technology that Yutai has highly praised in the industry, the new Vhold dynamic balance point for low-power200mA wirelesscharging input makes It is very suitable for those small-capacity batteries, new low-current wireless charging input, and APP pop-up Bluetooth charging boxes.

ETA9084/ETA9085 also reserves the EN enable pin for MCU control, which is less than 3V to turn off Boost, and is also very suitable for high-end independent binaural applications

In order to face the demands of harsh low-power standby and resisting high- voltage shocks, Yutai Semiconductor has launched the ETA9085 new charging and discharging three-in-one Bluetooth charging bin solution, which adopts ESOP8, ESOP10, and DFN2*3 three packages, which are compatible with Most placement machines require smaller packages to reduce space constraints. The chip continues to be upgraded on the original 9697, continuing the previous traditional " low power consumption " design, with four-light display at the same time. Meet the application requirements of the market, save the cost of MCU for customers, simple peripheral circuits, and greatly reduce the development cycle.

Compared with the traditional Bluetooth charging box circuit, ETA9085 has ultra-high reliability and the ultimate experience. It integrates 5V standby power consumption with power consumption less than 10μA in an ultra-small package, and also integrates charging with a maximum voltage of 20V, which greatly enhances the ultra-long standby time of the Bluetooth headset charging box and resists various uncertain input shocks. ability.

ETA9085 is an upgrade and perfect combination of Bluetooth dedicated charging case. We know that the use characteristics of the Bluetooth charging box are: the charging time of most earphones comes from the boost charging of the internal battery. Therefore, through the integrated chip design, compared with the traditional SOT23 package, the new generation of ETA9085 can use a larger heat dissipation structure to boost the charging of the earphone, which can effectively reduce the heat generated by the chip during operation, and organically charge and discharge Integration of protection and thermal power balance. Not only that, compared to the traditional discrete circuit combination, higher integration brings more sophisticated circuit periphery.

ETA9085 has a built-in high-performance linear charger with a voltage of up to 20V, which can resist the impact of various uncertain factors of household or car chargers, and completely avoid the problem of product damage on the consumer side. Lamp power indicator, NTC temperature monitor, programmable charging current, as well as the charging cut-off voltage and precise charging technology which are highly praised in the industry, the new Vhold dynamic balance point for low-power 200mA wireless charging input makes it very It is suitable for those small-capacity batteries, the new low-current wireless charging input, and the APP pop-up Bluetooth charging box.

ETA9085 also reserves the EN enable pin for MCU control, which is less than 3V to turn off Boost, and is also very suitable for high-end independent binaural applications . PWM automatic dual-frequency dual-mode switching enables ultra-low while perfectly avoiding the inductive sound caused by the PFM frequency of other traditional solutions falling below 20kHz; once the ETA9085 is connected to the load, it can Immediately work at a high frequency of 1MHz, so the peripheral inductors and capacitors are very small, which also makes the selection very easy to match.

In addition, ETA9085 also has the industry's sub-microamp level 5V standby input power consumption, which can be as low as 10μA. Even if the 5V boost is normally open, a 300mAh capacity battery can theoretically meet the standby for several years (Note: no Consider battery self-discharge), which will greatly extend the standby time and battery cycle life of the Bluetooth charging box. How to deal with the months-long logistics transportation, waiting in warehouses, long-term placement of direct-sale stores, and inadvertent idleness on the consumer side? The ultra-low can always make your brand charging box output energy at any time and be full of electricity, so that consumers can always use it immediately!

Now, ETA9085 also integrates more "scaring" black technology. ETA Semiconductor cooperates with multi-polymer battery manufacturers to enable ETA9085 to support "fast charging" for built-in high-speed lithium batteries through an external MCU. The dynamic current charging of up to 1C/2C is used within %, which will soon realize "charging the charging box for five minutes, allowing the Bluetooth headset to talk for 1 hour".
