3 Description

The DLP4621-Q1 automotive digital micromirror

device (DMD), combined with the DLPC230-Q1 DMD

controller and TPS99001-Q1 system management

and illumination controller, provides the capability to

achieve high-performance, high-resolution headlight

systems. The 2:1 aspect ratio supports very wide

aspect ratio designs, and the 0.9-MP resolution

enables high resolution symbol projection and

adaptive driving beam applications. The DLP4621-Q1

optical throughput is optimized to maximize lumens

with industry leading LEDs and laser technology.

The DLP4621-Q1 automotive DMD micromirror array

is configured for bottom illumination which enables

highly efficient and more compact optical engine

designs. The DLP4621-Q1 device is available in

a panel package for optimized system cost. The

package has low thermal resistance to the DMD array

to enable efficient thermal solutions.
