DESCRIPTION
The I.C. 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 mC compatible. Each channel (half-bridge) of
the device is controlled by a separate logic input,
while a common enable controls both channels.
The I.C. is mounted in three different packages.
This is
