The Logic Inputs are CMOS/TTL and
碌
P compatible.
The High Side switches are protected against unsafe
over current conditions.
Each full bridge is controlled by a separate Enable
and has a sense pin for the current sense resistor in-
sertion. Another feature is the thermal shutdown.
The L6225 is assembled in PowerDIP20(16+2+2),
PowerSO20 and SO20(16+2+2) packages.
