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.
Table 1. Device summary
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 input.
L6234 is available in 20 pin PowerDIP package
(16+2+2) and in PowerSO20.
