DMOS FULL BRIDGE DRIVER
DESCRIPTION
The circuit is a full bridge driver for motor control applications realized
in Multipower-BCD technology which combines isolated DMOS power
transistors with CMOS and Bipolar circuits on the same chip. By
using mixed technology it has been possible to optimize the logic
circuitry and the power stage to achieve the best possible
performance. The DMOS output transistors can operate at supply
voltages up to 42V and efficiently at high switching speeds. All the
logic inputs are TTL, CMOS and
µC
compatible. Each channel (half-
bridge) of the device is controlled by a separate logic input, while a
common enable controls both channels.
