SLA7071MPRT
Description
This document describes the SLA7070MPRT series, which are unipolar 2-phase stepping motor driver ICs. The SLA7070MPRT series employs a clock input method as a control signal input method, enabling full control of the device operation using only a few signal lines, instead of the conventional phase input method that requires about 10 signal lines.
Key Features
- Power supply voltages, VBB : 46 V (max.), 10 to 44 V normal operating range
- Logic supply voltages, VDD : 3.0 to 5.5 V
- Maximum output currents: 1 A, 1.5 A, 2 A, 3 A
- Built-in sequencer
- Full-, half-, and microstepping available (microstepping options are capable of full-, half-, quarter-, eighth-, and sixteenth-stepping Figure
- SLA7070MPRT packages are fully molded ZIPs with an exposed pad for heatsink mounting.
- Built-in sense resistor, RSInt
- All variants are pin-compatible for enhanced design flexibility
- ZIP type 23-pin molded package (SLA package)
- Self-excitation PWM current control with fixed off-time (microstepping options off-time adjusted automatically by step reference current ratio; 3 levels)
