PCA2117

Automotive LCD driver for character displays

Remarks:

1. It is necessary to run the power-down sequence before removing the supplies.

Depending on the application, care must be taken that no other signals are present at

the chip input or output pins when removing the supplies (refer to Section 10 on

page 76). Otherwise it may cause unwanted display artifacts. Uncontrolled removal of

supply voltages does not damage the PCA2117.
