LV8772
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.
