A4982
Description (continued)
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.
