Datasheet - production data

Description

The L6234 is a triple half bridge to drive a

brushless DC motor.

It is realized in BCDmultipower 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

structure is not affected by the second breakdown

effect, the RMS maximum current is practically

limited by the dissipation capability of the

package.

All the logic inputs are TTL, CMOS and µP

compatible. Each channel is controlled by two

separate logic inputs.

The L6234 device is available in a 20-pin

PowerSO20 package.
