LV8081GQ ^{Two channels Constant-current}
H-bridge Driver
Overview
The LV8081GQ is a two-channel constant-current driver that supports low-voltage operation. It is optimal for
constant-current drive of stepping motors (AF and zoom) in portable equipment such as camera cell phones.
Features
• Two channels constant-current H-bridge driver
• Built-in position detection comparator, SW for the photo reflector (independent control)
• Supports both 2 phase excitation drive and 1-2 phase excitation drive.
• Implemented in a low-power MOS IC process.
• Ultraminiature easy to solder UCT16 package (2.6 × 2.6 × 0.6mm)
• Built-in thermal shutdown circuit and Low voltage shutdown circuit.
• 1.8V input interface with battery supply.
• OUT1-3 short , OUT2-4 short and REG1-2 is short-circuited, and it is possible to correspond as 1ch driver.
