Acceleration sensor
Product Features:
In mobile terminal devices, wearable devices, acceleration sensors are becoming a standard device. For example, in smartphones and tablet PCs, three-axis acceleration sensors are used to achieve screen flip function; in bracelet watches, three-axis acceleration sensors can achieve functions such as pedometer and sleep monitoring; in TWS headphones, three-axis acceleration sensors are used as interfaces for human-computer interaction to identify operations such as click and double click.
Minchip has the ability to design the whole process of acceleration sensor, including MEMS design, ASIC design, packaging and testing. The product is feature-rich, with multiple interrupt outputs and a built-in FIFO with a depth of 32, which can effectively reduce the system power consumption of the whole machine, especially suitable for application scenarios with strict requirements on power consumption, such as bracelets and watches.
