A3980
Automotive DMOS Microstepping Driver with Translator
The A3980 is a complete microstepping motor driver with built-in
translator for easy operation. It is designed to operate bipolar stepper
motors in full-, half-, eighth-, and sixteenth-step modes, at up to 35 V
and ±1 A. The A3980 includes a
fi
xed off-time current regulator which
has the ability to operate in slow, fast, or mixed decay modes. This
results in reduced audible motor noise, increased step accuracy, and
reduced power dissipation.
The translator is the key to the easy implementation of the A3980.
Simply inputting one pulse on the step input drives the motor one
microstep. There are no phase sequence tables, high frequency control
lines, or complex interfaces to program. The A3980 interface is an ideal
fi
t for applications where a complex μP is unavailable or overburdened.
Internal synchronous recti
fi
cation control circuitry is provided to
improve power dissipation during PWM operation.
Internal circuit protection includes: thermal shutdown with hysteresis,
overvoltage lockout (OVLO), undervoltage lockout (UVLO), and
crossover current protection. Special power-up sequencing is not
required. In addition, two diagnostic fault
fl
ags provide indication of
shorts or opens on the motor windings.
The A3980 is supplied in a low-pro
fi
le (1.1 mm) 28L TSSOP with
exposed thermal pad (part number suf
