Features
q
Employs a constant-current chopper control method.
q
Integrates power MOSFETs and monolithic chip control cir-
cuitry in a single package.
q
One-fifth the size and one-fourth the power dissipation com-
pared with conventional SANKEN ICs
s
Constant Current Chopper Method
In the constant current chopper method, a voltage higher than
the rated voltage of the motor is applied and when the current
rises, the chopper transistor is switched on thereby shortening
the current rise time. After the current rises, the coil current is
held by the PWM chopper to a constant current level deter-
mined by the current sense resistor. This method has the ad-
vantage of improving the motor's high frequency response and
the efficiency response and efficiency of the driver circuitry.
q
Eliminates the need for heatsink thereby decreasing part-in-
sertion workload and increasing flexibility in mounting.
q
Reduces the size of power supplies required.
q
Lineup: 2-phase excitation, 2-phase/1-2 phase excitation,
2W1-2 phase micro-step support ICs
s
Applications
The SLA7000 and SMA7000 series are ideal for the following
applications.
q
Sheet feeders and carriage drivers in printers.
q
Sheet feeders for PPC and facsimile machines.
q
Numeric control equipment.
q
Industrial robots.
s
Handling Precautions
q

GE Toshiba Silicone Co., Ltd.: YG-6260
Dow Corning Toray Silicone Co., Ltd.: SC102
Please be careful when selecting silicone grease since the oil
in some grease may penetrate the product, which will result
in an extremely short product life.
