3 Description

The DLPC8424, DLPC8444, and DLPC8454 are

1080p FHD digital display controllers for TI DLP®

Products. The DLP chipset comprises one display

controller, one matched DMD, the DLPA3085 or

DLPA3082 power management IC, and the DLPA100

motor driver IC (for laser-phosphor illumination

systems only). This chipset fits display systems that

require high resolution and high brightness in a small

form factor. For reliable operation, the DLPC8424

or DLPC8444 or DLPC8454 display controller must

always be used with the correct DMD and the

DLPA3085 or DLPA3082 PMIC. Note: DLPA3085 is

not supported by the DLPC8454.
