In the wave of innovation in intelligence and interactive experience, haptic feedback has become one of the core technologies of human-computer interaction. To meet the consumer electronics,IoTand esports fields' demand for haptic feedback withhigh performance, low bandwidth, and low latency,AW8625Xseries haptic driver chips have emerged. With innovative design and precise performance, this series of chips is redefining industry standards for haptic feedback, providing a one-stop solution for developers and manufacturers worldwide.
Core Product Advantages
AW86253QNRandAW86254CSRMinimum Supported Voltage1.8V, not only supports the wide power supply range required by silicon anode lithium batteries but also meets the power supply needs of dual-cell dry batteries.AW8625XSeriessimultaneously supports single-power and dual-power systems. When powered by dual supplies, by independently regulating the voltage of DVDD(power supply for the digital part) and VDD(power supply for the driver part) , performance and power consumption can be flexibly balanced.
