3 OUT1
Half bridge driver
Output
Mirror common Output
4 OUT2
Half bridge driver
Output
Mirror x/y control Output
5 OUT3
Half bridge driver
Output
Mirror x/y control Output
6 VS Supply Battery Supply Input (all VS pins have to be connected externally)
7 VS Supply Battery Supply Input (all VS pins have to be connected externally)
8 SI Digital Input SPI interface Serial Data Input

ISOUT /
PWM2
Digital Input /
Analog Output
PWM control Input / Current Sense Output. This pin is a bidirectional pin. Depend-
ing on the selected multiplexer bits, an image of the instant current of the corres-
ponding HS stage can be read out.
This pin can also be used as PWM control input pin for OUT5, OUT8 and OUT10.

23 VS Supply Battery Supply Input (all VS pins have to be connected externally)
24 VS Supply Battery Supply Input (all VS pins have to be connected externally)
25 ECON ECM driver Output
Electrochromic mirror control DAC output. If the Electrochrome feature is selec-
ted, this output controls an external Mosfet, otherwise it remains in high−imped-
ance state.
If the electrochrome feature is not used in the application and not selected via SPI
the pin can be connected to VS.
