Description
The L6219 is a bipolar monolithic integrated circuits intended to control and
drive both winding of a bipolar stepper motor or bidirectionally control two
DC motors.
The L6219 with a few external components form a complete control and drive
circuit for LS-TTL or microprocessor controlled stepper motor system. The
power stage is a dual full bridge capable of sustaining 46V and including four
diodes for current recirculation.
A cross conduction protection is provided to avoid simultaneous cross
conduction during switching current direction.
An internal pulse-width-modulation (PWM) controls the output current to 750 mA
with peak startup current up to 1 A.
Wide range of current control from 750 mA (each bridge) is permitted by means
of two logic inputs and an external voltage reference. A phase input to each
bridge determines the load current direction. A thermal protection circuitry
disables the outputs if the chip temperature exceeds safe operating limits.
Features
■ Able to drive both windings of bipolar stepper motor
■ Output current up to 750 mA each winding
■ Wide voltage range: 10 V to 46 V
■ Half-step, full-step and microstepping mode
■ Built-in protection diodes
■ Internal PWM current control
■ Low output saturation voltage
■ Designed for unstabilized motor supply voltage
■ Internal thermal shutdown
