DESCRIPTION
The L6227 isa dual full bridge driver for motor control
manufactured
which combines isolated DMOS power transistors
with CMOS and bipolar circuits on the same chip.
The Logic Inputs are CMOS/TTL and
μ
P compatible.
Additional circuitry to realize a constant off time PWM
control has been implemented for each bridge.
Each full bridge is controlled by a separate Enable
and has a sense pin for the current sense resistor in-
sertion. Other features are the protection of the high
side switches against unsafe over current conditions,
the thermal shutdown and the inhibit function that al-
lows to disable all bridges and to reduce the quies-
cent current to very low values (typ. 1.1mA).
The L6227 is assembled in PowerDIP24(20+2+2),
PowerSO36 and SO24(20+2+2) packages.
