Overview
The LV8772 is a stepping motor driver, which is capable of micro-step drive and supports 4W 1-2 phase excitation. It
is stepping motors used in office equipment and amusement applications.
Features
• Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2.5A)
• Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase
• BiCDMOS process IC
• Excitation step proceeds only by step signal input
• Motor current selectable in four steps
• Output short-circuit protection circuit incorporated
• Unusual condition warning output pins
• No control power supply required

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.
