Stepper Motor Driver IC

GENERAL DESCRIPTION

FEATURES

The SGM42630 is a bipolar stepper motor driver suitable

for automated positioning and movement control in

equipment such as printers, scanners and robotic

mechanisms. To control the stepper motor, two H-bridges

are integrated in the device for the two motor windings

along with a microstepping indexer logic. Bridge currents

are regulated by chopping the motor supply voltage

across the windings.

● Motor Power Supply Voltage Range: 8V to 35V

● PWM with up to 2.6A Current for each Winding

● Low On-Resistance: 0.29Ω for HS + LS, @ +25℃

● Microstepping Indexer: 1, 1/2, 1/4 and 1/8

● Step and Direction Interface

● Programmable Decay, Blanking and Off-Time

● Auto-Decay Mode

● UVLO for VM, VCC, VCP, VGD Voltages

● Over-Current Protection (OCP)

The step (STEP) and direction (DIR) inputs are provided

for simple interfacing to the controller. The device also

provides two microstepping input pins (USM0 and USM1)

to choose the step size (full, half, quarter and eighth step).

● Thermal Shutdown (TSD)

● Available in a Green TSSOP-28 (Exposed Pad)

Package

Fast, slow and mixed (fast then slow) decay modes are

selectable by applying proper voltage to DECAY input.

Programmable blanking and off-time of the H-bridge

PWM and selectable decay modes make the device

very flexible and capable of driving a wide range of

stepper motors with up to 2.6A per winding.

APPLICATIONS

Robotic Mechanisms

Textile Equipment

Scanners

Positioning and Tracking

Printers

A number of protection features are provided in the device

including under-voltage lockout, short-circuit, over-current

and over-temperature shutdown.

The device is available in a Green TSSOP-28 (Exposed

Pad) package.
