Connections diagram Flip Chip 12-bump (STCD23x0, 3-channel)
EN1~EN3 can be active high or active low. STMicroelectronics offers several polarity
options, refer to
Connections diagram Flip Chip 16-bump (STCD24x0, 4-channel)
OPT1 is used to configure EN1 and EN2 polarity. Connect OPT1 to V
and EN2 active high or connect OPT1 to GND to configure EN1 and EN2 active low. In the
same way OPT2 is used to configure EN3 and EN4. STMicroelectronics offers different
control options, refer to
