PCA2117

Automotive LCD driver for character displays

Remarks:

1. VLCDx[8:0] has to be set to such a value that the resultant VLCD, including the

temperature compensation, is higher than VDD2.

2. The programmable range of VLCDx[8:0] is from 0h to 1FFh. It would allow achieving a

VLCD of higher voltages but the PCA2117 has a built-in automatic limitation set to

16 V.

8.4.4 VLCD drive capability

Figure 20 to Figure 22 illustrate the drive capability of the internal charge pump for various

conditions. VLCD is internally limited to 16 V.

(1) VLCDx[8:0] must be set such that VLCD > VDD2.

(2) Automatic limitation for VLCD > 16 V.
