EVAL6230QR

EVAL6230QR Demonstration board mounting the L6230Q three-phase brushless DC motor driver Data brief Features Operating supply voltage from 8 to 52 V 2.8 A output peak current (1.4 A ) r.m.s. R 0.73 typ. value T = 25 C DS(on) J Integrated fast freewheeling diodes Operating frequency up to 100 kHz Non-dissipative overcurrent detection and protection Cross conduction protection Diagnostic output Uncommitted comparator Thermal shutdown Undervoltage lockout Description The L6230Q is a DMOS fully integrated three- phase motor driver with overcurrent protection, optimized for FOC applications thanks to the independent current sensing. Realized in BCD multipower technology, the L6230Q features a non-dissipative overcurrent protection on the high-side power MOSFETs and thermal shutdown. An uncommitted comparator with open-drain output is available.
