Overview
The L6234PD013TR is a triple half-bridge motor driver designed to drive brushless DC motors. It is manufactured by STMicroelectronics and utilizes BCDmultipower technology, which integrates isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. This mixed technology approach allows for optimized logic circuitry and power stage performance. The device is particularly suited for high-current applications, as the DMOS structure is not affected by the second breakdown effect, and the RMS maximum current is limited by the package's dissipation capability. The L6234PD013TR is available in a 20-pin PowerSO20 package and is compatible with TTL, CMOS, and microprocessor logic inputs.
