  • The L6235Q is a DMOS fully integrated 3-phase motor driver with overcurrent protection. Realized in BCDmultipower technology, the device combines isolated DMOS power transistors with CMOS and bipolar 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. Available in QFN48 7x7 package, the L6235Q features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.

    Key Features

    • Operating supply voltage from 8 to 52 V
    • 5.6 A output peak current
    • RDS(on)0.3 Ω typ. value @ TJ= 25 °C
    • Operating frequency up to 100 kHz
    • Non-dissipative overcurrent protection
    • Diagnostic output
    • Constant tOFFPWM current controller
    • Slow decay synchronous rectification
    • 60° and 120° Hall effect decoding logic
    • Brake function
    • Tacho output for speed loop
    • Cross conduction protection
    • Thermal shutdown
    • Undervoltage lockout
    • Integrated fast freewheeling diodes
