L6470PD Typical application Circuitry

The L6470PD is a microstepping motor driver with motion engine and SPI. It is manufactured by STMicroelectronics.This IC is made to drive both windings of a bipolar stepper motor or to control two DC motors in opposite directions.

Key Features of L6470PD:

- Integrated Microstepping Indexer: The L6470PD has an integrated microstepping indexer which simplifies motion control. It also has an embedded power MOSFETs which allows for 7A peak output.

- Supply Voltage: It operates at a supply voltage from 8V to 45V.

- Advanced Control Features: It has advanced control features such as motion profile generation with trapezoidal or parabolic speed profiles. The L6470PD also features stall detection, and the motor torque can be controlled in real time via the SPI.

- Protection: It features under-voltage lock-out protection and thermal shutdown and has a programmable alarm.

Applications of L6470PD:

The L6470PD is ideal for robotics, vending machines, textile machines, computer peripherals such as printers and scanners, surveillance systems, and point of sale terminals.

Circuit Connection Example - Driving a Bipolar Stepper Motor:

1. Power Supply: Connect your power supply (8V to 45V) to the VIN and GND pins of the L6470PD.

2. Motor Connections: Connect your bipolar stepper motor to the OUT1A, OUT1B, OUT2A, and OUT2B pins of the L6470PD. These pins will directly drive the two windings of your stepper motor.

3. SPI Interface: Connect the SCK, SDI, and SDO pins of the L6470PD to the SPI interface of your microcontroller. This will allow the microcontroller to send commands and receive status information from the L6470PD.

4. Reset and Flag Pins: Connect the nRESET and nFLAG pins to the appropriate I/O pins of your microcontroller. The nRESET pin is used to reset the L6470PD, while the nFLAG pin will be set when a warning or error condition is detected.

Design Considerations when using L6470PD:

- Heat Dissipation: Consider heat dissipation in your design, as the L6470PD can deliver up to 7A to the motor, which may generate significant heat.

- Power Supply Decoupling: Decoupling capacitors should be placed close to the power supply pins (VIN and GND) to ensure stable operation.

- Motor Selection: The selection of the motor should be done with the peak current rating and operating voltage range of the L6470PD in mind.

Overall, the L6470PD is a feature-packed solution for driving bipolar stepper motors or two DC motors, offering precise control, protection, and flexibility.
