NCV7705, NCV7706
Mirror-Module Driver-IC
The NCV7705/NCV7706 is a powerful Driver−IC for automotive
body control systems. The IC is designed to control several loads in
the front door of a vehicle. The monolithic IC is able to control mirror
functions like mirror positioning, heating and folding. In addition,
NCV7706 includes the electro−chromic mirror feature. The device
features four high−side outputs to drive LEDs or incandescent bulbs

(up to 5/10 W). To allow maximum flexibility, all lighting outputs can
be PWM controlled thru PWM inputs (external signal source) or by an
internal programmable PWM generator unit. The
NCV7705/NCV7706 is controlled thru a 24 bit SPI interface with
in−frame response.
