L6235N

The L6235N is a 3-phase DMOS fully integrated Motor Driver with over-current protection. Realized in BCD technology, the device combines isolated DMOS power transistors with CMOS and bi-polar circuits on the same chip. The device includes all the circuitry needed to drive a 3-phase BLDC motor including a 3-phase DMOS bridge, a constant off time PWM current controller and the decoding logic for single ended hall sensors that generates the required sequence for the power stage.

• Non-dissipative over-current detection and protection
• Diagnostic output
• Constant tOFF PWM current controller
• Slow decay synchronization rectification
• Brake function
• Tachometer output for speed loop
• Cross conduction protection
• Thermal shutdown
• Under-voltage lockout
• Integrated fast freewheeling diodes
