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.
