ZHCSG32B March 2017 – February 2020 TCA9800
PRODUCTION DATA.
The system designer must first select the correct variant of the TCA980x family for the load. In order to do this, the information in Table 10 and Table 11 must be known. The setup in Figure 34 is used for these example design requirements.
