STMicroelectronics | L6234PD

The L6234PD 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 and mP compatible. Each channel is controlled by two separate logic input.
