DESCRIPTION
The L6234 is a triple half bridge to drive a
brushlessmotor.
ORDERING NUMBERS: L6234 (POWER DIP 16+2+2)
L6234PD (PowerSO20)
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
achievethe 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 P com-
µ
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.

ones), as well as the others, have a minimum
thermal connection with the external world (very
thin strips only) so that the dissipation takes place
through still air and through the PCB itself.
It is the same situation of point above, without any

. The thermal resistance is referred to
the thermal path from the dissipating region on
the top surface of the silicon chip, to the points
along the four central pins of the package, at a
distance of 1.5 mm away from the stand-offs.

PowerSO20 package can be found in:

If a dissipating surface, thick at least 35 µm, and
with a surface similar or bigger than the one
shown, is created making use of the printed cir-
cuit.
Such heatsinking surface is considered on the
bottomside of an horizontal PCB (worst case).

CIRCUIT DESCRIPTION
L6234 is a triple half bridge designed to drive
brushlessDC motors.
Each half bridge has 2 power DMOS transistors
with RdsON = 0.3Ω. The 3 half bridges can be
controlled independentlyby means of the 3 inputs
IN1, IN2, IN3 and the 3 inputs EN1, EN2, and
EN3. An external connection to the 3 common
low side DMOS sources is provided to connect a
sensing resistor for constant current chopping ap-
plication.
The driving stage and the logic stage are de-
signed to work from 7V to 52V.
