L6235 DMOS driver for 3-phase brushless DC motor Datasheet - production data Features  Operating supply voltage from 8 to 52 V  5.6 A output peak current (2.8 A DC)  RDS(ON) 0.3  typ. value at Tj = 25 °C  Operating frequency up to 100 KHz  Non-dissipative overcurrent detection and protection 3R ZHU',3  Diagnostic output  Constant tOFF PWM current controller  Slow decay synchr. rectification  60° and 120° hall effect decoding logic  Brake function  Tachometer output for speed loop  Cross conduction protection  Thermal shutdown  Undervoltage lockout 3RZHU62  Integrated fast freewheeling diodes Description The L6235 device is a DMOS fully integrated 3-phase motor driver with overcurrent protection. Realized in BCD technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. 62  2UGHULQJQXPEHUV /1 3RZHU',3 /3' 3RZHU62 /' 62 October 2014 This is information on a product in full production. 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 PowerDIP24 (20 + 2 + 2), PowerSO36 and SO24 (20 + 2 + 2) packages, the L6235 device features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown.
