LCD Module Calibrator

remove flicker. The ISL45042 can be used to digitally adjust

The output of the ISL45042 is connected to an external

obtained, the settings can be stored in the non-volatile

EEPROM memory, which would then be automatically

recalled during every power-up.

programming is through a single interface pin (CTL). Once

the desired programmed value is obtained, the Counter

Enable pin (CE) can be used to prevent further adjustment

or programming.

The full-scale sink current of the ISL45042 is set using an

external resistor connected to the SET pin. The full-scale

sink current determines the lowest voltage of the external

voltage divider.

The ISL45042 is available in an 8 Ld 3mmx3mm TDFN

package with a maximum thickness of 0.8mm for ultra thin

LCD panel design.

NOTES:

1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on

reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is

RoHS compliant and compatible with both SnPb and Pb-free

soldering operations). Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.

3. For Moisture Sensitivity Level (MSL), please see device information

page for ISL45042. For more information on MSL please see

techbrief TB363.
