PBL3717A - STEPPER MOTOR DRIVER

General Description

The PBL3717Ais a monolithic IC which controls and drives one phase of a bipolar stepper motor with chopper control of the phase current.

Current levels may be selected in threesteps by means of two logic inputs which select one of three current comparators.

PBL3717A STEPPER MOTOR DRIVER . . . . . . . . FULL STEP - HALF STEP - QUARTER STEP OPERATING MODE BIPOLAR OUTPUT CURRENT UP TO 1 A FROM 10 V UP TO 46 V MOTOR SUPPLY VOLTAGE LOW SATURATION VOLTAGE WITH INTEGRATED BOOTSTRAP BUILT IN FAST PROTECTION DIODES EXTERNALLY SELECTABLE CURRENT LEVEL OUTPUT CURRENT LEVEL DIGITALLY OR ANALOGUE CONTROLLED THERMAL PROTECTION WITH SOFT INTERVENTION Powerdip 12 + 2 + 2 (Plastic Package) ORDER CODE : PBL3717A DESCRIPTION The PBL3717Ais a monolithic IC which controls and drives one phase of a bipolar stepper motor with chopper control of the phase current. Current levels may be selected in threesteps by means of two logic inputs which select one of three current comparators. When both of these inputs are high the device is disabled.
