All the logic inputs are TTL, CMOS By using mixed technology it has been possible to and C compatible. Each channel (half-bridge) of optimize the logic circuitry and the power stage to achieve the best possible performance. The the device is controlled by a separate logic input, DMOS output transistors can operate at supply while a common enable controls both channels. The I.C. is mounted in three different packages. voltages up to 42V and efficiently at high switch- BLOCK DIAGRAM July 2003 1/20 This is advanced information on a new product now in development or undergoing evaluation.
