Precautions for using CST118S chip
1. The above recommended circuits and parameters are only applicable to ordinary remote-controlled car toys. Please use other toys and motor drives according to the actual situation when using 118.2. The continuous current driving capability is affected by factors such as packaging form, VDD, VCC, chip differences, and environmental temperature. The specifications provide parameters for reference only. In practical use, please consider a certain margin based on the product.
3. CST118S is designed and manufactured using MOS technology, which is sensitive to static electricity. It is required to pay attention to anti-static measures throughout the entire process of packaging, transportation, processing, and production.
