Note 5: 4.0V V CON 4.5V Supply bypass: Power supply VS should have sufficient bypass capacitors to ensure proper operation, otherwise it may be unstable and reduce efficiency, and the output may be oscillated. Vs power supply should be add a ceramic capacitor at least 1μF, and then a low ESR value of the bypass capacitor in parallel, the size of selected at least 10μf/A; For V CC should also add a ceramic capacitor with 0.1μF and a low ESR value with 6.8μF-10μF of the bypass capacitor in parallel. 8.Package Specifications of HMSK4310 Large Current Pulse Width Modulation Amplifier of Brushless Motor Driver Web : sales@ecrim.cn Phone: Fax:
