DDX
Table 26.
The DDX
power devices can use different output modes. The recommended use is OM = 10. When
OM=11 the CSZ bits determine the size of the DDX
Table 27.
DDX® variable compensating pulse size
The DDX® variable compensating pulse size is intended to adapt to different power stage
ICs. Contact ST for support when using this function.
