DESCRIPTION
The L6234 is a triple half bridge to drive a
brushless motor.
It is 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 output DMOS transistors can sustain a very
high current due to the fact that the DMOS struc-
ture is not affected by the second breakdown ef-
fect, the RMS maximum current is practically lim-
ited by the dissipation capability of the package.
All the logic inputs are TTL, CMOS and
μ
P com-
patible. Each channel is controlled by two sepa-
rate logic input.
L6234 is available in 20 pin POWER DIP package
(16+2+2) and in PowerSO20.
