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.
