Active Matrix LCD Bias Supply Operates from Battery Input - 02/03/00 EDN-Design
Ideas: Many active-matrix-LCD applications need multiple voltages for
thin-film-transistor (TFT)bias. Typically, three voltages are necessary: 5V for
column driver; a positive voltage, such as 10V; and a negative voltage, such -5V, for
TFT gate drive, or row driver. For handheld electronic devices, a battery
must.....(design idea added 11/05)
AN10 Automotive Relay Drivers using the Zvn4206av: Protection Free Interfacing with
Avalanche Rated MOSFETs - Zetec Semiconductors Applications Notes An
alternative solution is provided to usual large package Darlington effected
relay driver. The ZVN4206AV has been designed, processed and rated to withstand
significant energy within breakdown region. This allows part to absorb
back-emf and transient energy, reby allowing lower component count circuits.
