Overview
The LV8549MC is a 2-channel low saturation voltage forward/reverse motor driver IC. It is optimal for Full step motor
drive in 12V system products.
Functions
• DMOS output transistor adoption (Upper and lower total RON=1Ω typ)
• The compact package (SOIC10) is adopted.
• VCC max=20V, IO max=1A
• For one power supply (The control system power supply is unnecessary.)
• Current consumption 0 when standing by

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
