The Logic Inputs are CMOS/TTL andµP 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-

side switches against unsafe over current conditions,

the thermal shutdown and the inhibit function that al-

CIRCUIT DESCRIPTION

The L6227 is a dual full bridge IC designed to drive DC or Stepper motors and other inductive loads. Each bridge has

4 power DMOS transistors with a typical R of 0.73 Ohm. Any of the 4 half bridges can be controlled indepen-

DS(ON)

dently by means of the 4 TTL/CMOS compatible inputs IN1 , IN2 , IN1 , IN2 , and 2 enable EN , EN .

External connections are provided so that sensing resistor can be added for constant current chopping application.

A non dissipative current sensing on the supply rails of the high side power DMOSs of each bridge, together

with an Internal Reference and an internal open drain, with a pull down capability of 4mA (typical value) will pull

to GND the ENABLE pin of the bridge under fault conditions, turning OFF all the four PowerMOSs. This ensures

a protection against Short Circuit to GND and between two phases of each of the two independent full bridges.

By using an external R-C on the EN pins, the off time before recovering normal operation conditions after a fault

can be easily programmed, by means of the accurate threshold of the logic inputs. Note that protection against

short to the supply rail is typically provided by the external current control circuitry. The trip point of this protec-

tion is internally set at 2.8A (typ value). For each of the two indipendent bridges a monostable and a comparator

can be used to perform a constant t current control.

off

The L6227 also features an inhibit function to put the device in stand-by mode, reducing the current consump-

tion to 1.1mA typ.

These features makes the L6227 a complete bipolar stepper motor driver, or a Dual DC Motor Driver, that out-

performs the component currently available on the market.
