A4982
Description (continued)
DMOS Microstepping Driver with Translator
And Overcurrent Protection
results in reduced audible motor noise, increased step accuracy,
and reduced power dissipation.
Internal synchronous rectification control circuitry is provided
to improve power dissipation during PWM operation. Internal
circuit protection includes: thermal shutdown with hysteresis,
undervoltage lockout (UVLO), and crossover-current protection.
Selection Guide
Special power-on sequencing is not required.
The A4982 is supplied in two surface mount package, the ET, a
5 mm × 5 mm, 0.90 mm nominal overall package height QFN
package, and the LP package, a 24-pin TSSOP. Both packages have
exposed pads for enhanced thermal dissipation, and are lead (Pb)
free (suffix –T), with 100% matte tin plated leadframes.
