ST6208 Lens Motor Driver IC for Camcorder & Security Camera

Name: ST6208 Lens Motor Driver IC for Camcorder & Security Camera
Brand: STST
SKU: ST6208

ST6208

The ST6208 is a lens motor driver IC for camcorders and security cameras, integrating a PID-controlled DC motor driver for the iris and two stepper motor (STM) drivers for zoom and focus control — a complete single-chip lens drive solution. Configured via an SPI serial interface, it supports 256-microstep driving technology for ultra-low-noise operation, and integrates a Hall-signal amplifier, an 8-bit DAC and a 10-bit ADC, plus two open-drain LED driver outputs. With over-temperature protection and dual under-voltage lockout, the ST6208 is available in QFN44/LGA44 (6×6mm) packages for camcorders, security cameras, consumer products, robotics and medical devices.

Product details

Overview

The ST6208 is a lens motor driver IC designed for camcorders and security cameras. It integrates a PID-controlled DC motor driver for the iris and two stepper motor (STM) drivers for zoom and focus control, providing a complete single-chip lens drive solution. Configured via an SPI serial interface, the device supports 256-microstep driving technology for ultra-low-noise operation, and integrates a Hall-signal amplifier, an 8-bit DAC for Hall bias control and a 10-bit ADC, plus two open-drain LED driver outputs. With over-temperature protection and dual under-voltage lockout (UVLO1/UVLO2), the ST6208 is available in QFN44/LGA44 (6×6mm) packages.
