ST electronics L6219 DIP-24 STEPPER MOTOR DRIVER

FULL-BRIDGE PWM MOTOR DRIVER

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.

Description

BD7907FS is a 6-channel driver IC that integrates all
drivers necessary for CD-ROM, and DVD-ROM systems
into a single chip.  The built-in 2-channel sled motor
driver is used for the stepping motor.  Low heat operation
can be achieved by applying the PWM driving system for
sled and spindle motor drivers.

 Features

1) Motor drivers for spindle, sled (2-channel) and
loading, and actuator drivers for tracking are all
integrated into a single chip.
2) ON/OFF for each driver, brake mode switching of
spindle and stand-by mode switching can be
controlled by 2-wire serial data.  
3) Built-in triangular-wave generator
4) SSOP-A54 package
5) Built-in thermal shut-down circuit

6) Highly efficient by applying the PWM drive and
Low ON resistance POWER MOSFET
7) Built-in current limit, hall bias, short brake, FG 3-phase
synthesis output, and reverse protection circuit

8) Highly efficient due to the PWM drive
9) Built-in 2-channel for the stepping motor

10) Low noise due to the linear BTL driver and smooth spin

 Applications

CD-ROM, DVD-ROM, and any other equipment driven by optical DISC
