DESCRIPTION

· The L6235 is a fully integrated three-phase motor driver with overcurrent protection, designed using MultiPower-BCD technology.

· It combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip.

· The device includes a three-phase DMOS bridge, a constant off-time PWM current controller, and decoding logic for single-ended Hall sensors.

· Available in PowerDIP24, PowerSO36, and SO24 packages.

FEATURES

· Operating supply voltage from 8 to 52V.

· Output peak current of 5.6A (2.8A DC).

· RDS(ON) typical value of 0.3Ω at Tj = 25°C.

· Operating frequency up to 100kHz.

· Non-dissipative overcurrent detection and protection.

· Diagnostic output, constant tOFF PWM current controller, and slow decay synchronous rectification.

· 60° & 120° Hall effect decoding logic, brake function, and tacho output for speed loop.

· Cross-conduction protection, thermal shutdown, undervoltage lockout, and integrated fast freewheeling diodes.

APPLICATIONS

· Suitable for driving three-phase brushless DC motors.

· Ideal for applications requiring overcurrent protection and thermal shutdown.

· Used in systems needing Hall sensor decoding and PWM current control.
