    CST118S Precautions for chip use:
    1、 The above recommended circuits and parameters are only applicable to ordinary remote control car toys. Please use 118 for other toys and motor drives according to the actual situation.
    2、 The continuous current drive capability is affected by package form, VDD, VCC, chip difference, ambient temperature and other factors. The parameters given in the specification are for reference only. In actual use, please consider a certain margin according to the product.
    3、  CST118S is designed and manufactured by MOS process and is sensitive to static electricity. It is required to pay attention to anti-static measures in the whole process of packaging, transportation, processing and production.
