Description
The L6230 is a DMOS fully integrated three-
phase motor driver with overcurrent protection,
optimized for FOC application thanks to the
independent current senses.
Realized in BCDmultipower technology, the
device combines isolated DMOS Power
Transistors with CMOS and bipolar circuits on the
same chip.
An uncommitted comparator with open-drain
output is available.
Available in PowerSO36 and VFQFPN-32 5x5
packages the L6230 features a non dissipative
overcurrent protection on the high side power
MOSFETs and thermal shutdown.
