The voltage compare to VSS port. *2 The case when internal reference voltage generation circuit (VBA output) is used. The voltage compare to VSS port. *3 When the boosting circuit is used, supply voltage VEE should be used within the limit. When driving LCD panel by use of internal boosting circuit, it is possible to short VDD and VEE. *4 Please keep the relation, VSS < V4 < V3 < V2 < V1 < VLCD ≤V OUT. *5 When the internal voltage regulator circuit is used, reference voltage VREF should be used within the limit. Please keep the relation VREF ≤V EE . |
