LV8082LP
Overview
Two Constant-current H-Bridge Driver channels
The LV8082LP is a two-channel constant-current driver that supports low-voltage operation. It is optimal for constant-current drive of stepping motors (AF and Shutter) in portable equipment such as camera cell phones.
Features
* Two constant-current H-bridge driver channels * Built-in power supply switch and position detection comparator 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 x 2.6mm) * Built-in thermal protection and low-voltage sensing circuits

Constant-voltage calculation : VOUT = VC x 2 Example : When an VOUT of 2V is required, VC must be 1V Constant-current calculation : IOUT = 0.1 / RF Example : When an IOUT of 100mA is required, RF must be 1. Usage Notes The constant current is set by the resource RF connected between RFG and ground according to the formula shown above.

Note : When off, a high-impedance state. * Channel 1 functions as a constant voltage block (OUT1 and OUT2). Channel 2 functions as a constant-current block (OUT3 and OUT4). * The IC goes to the standby state with a low-level input, and to the operating state with a high-level input. * When the control inputs are both high, the IC switches to brake mode.
