LV8080LP
Overview
The LV8080LP is a two-channel con s tant-current driver that supports low-voltage operatio n. 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 power supply switch and position detection co mparator for use with a photoreflector
• Supports both 2-phase drive and 1-2 phase drive.
• Implemented in a low-power MOS IC process.
• Ultraminiature easy to solder VCT16 package (2.6 × 2.6mm)
• Built-in thermal protection and low-voltage sensing circuits

Constant-current calculation : IOUT = 0.1 ÷ RF Example : When an IOUT of 100mA is required, RF must be 1Ω.
Usage Notes
The constant current is set by the resource RF connected between RFG and grou nd according to t he fo r mula shown
above.

14 PI/PR A switch, with NMOS open-drain output, used to turn
on/off the power supply of the position sensor unit. When
using this switch, connect the position sensor unit
between this pin and the VCC pin.
On/off control of this switch is accomplished by CONT
pin. Setting the CONT pin high turns on the switch.
