Part Number : L6234
Description : THREE PHASE MOTOR DRIVER
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 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 andµP compatible. 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.
