L6234PD013TR

L6234PD013TR is a three-phase motor driver. It is a triple-half bridge to drive a brushless DC motor. It is realized in BCD multipower 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.

• Cross conduction protection, TTL compatible driver
• Thermal shutdown, intrinsic fast free wheeling diodes
• Input and enable function for each half bridge
• Supply voltage range from 7 to 42V
• Reference voltage is 10V typ (VS = 42V, Tj = 25°C)
• Quiescent supply current is 6.5mA typ (VS = 42V, Tj = 25°C)
• Dead time protection is 300ns typ (VS = 42V, Tj = 25°C)
• Leakage current is 1mA max (VS = 42V, Tj = 25°C)
• ON resistance is 0.3ohm (VS = 42V, Tj = 25°C)
• PowerSO20 package, junction temperature range from -40 to 125°C
