Description
AI
The NCV7705 is a powerful driver for automotive body control systems. The device 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 including the electro-chromic mirror feature. The device features four high-side outputs to drive LEDs or incandescent bulbs (up to 10W). 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 is controlled through a 24 bit SPI interface with in-frame response.
