SLA7080M Series  
Unipolar 2-Phase Stepping Motor Driver ICs  
Features and Benefits  
Description  
Power supply voltage, VBB, 46 V maximum; 10 to 44 V  
normal operating range  
ThisdocumentdescribesthefunctionandfeaturesofSLA7080M  
series, which are unipolar 2-phase stepping motor driver ICs.  
Fourlevelsofoutputcurrentareavailablefromtheincorporated  
MOSFETs, corresponding to the rated output current ratings.  
All current ratings are available with protection against motor  
coil shorts or motor open wire detection.  
Logic supply voltage, VDD, 3 to 5.5 V  
Four output currents, IO(max), options: 1, 1.5, 2, and 3 A  
Stepping control for phase input (full or half step)  
Built-in sense resistor detects motor current  
Compact ZIP 23-pin molded package (SLA package)  
Self-excitation PWM control with fixed off-time  
Built-in synchronous rectifying circuit reduces losses at  
PWM-off  
The SLA7080M series has a multichip structure, for enhanced  
thermaldispersion.TheControlIC(MIC),fourpowerelements  
(MOSFET), and dual sense resistors, are all separate ICs.  
Synchronous PWM function prevents noise generation in  
motor Hold mode  
Sleep function reduces power consumption of drivers in  
Standby mode  
Built-in sense resistors for each phase allow accurate track-  
ing of performance without additional external components.  
Low-powersleepmodeaswellasreducedpowerduringPWM  
off-time maximize energy savings.  
Protection circuit detects motor coil open/short and  
prevents overheating due to avalanche breakdown  
Externally-adjustable (3.2 μs/5.2 μs) blanking time  
(minimum on-time)  
Package: 23-pin ZIP (type SLA)
