Panasonic provides a line-up of Stepping Motor Driver ICs for Lens that is capable in zoom focus control, iris control and mirror shutter functions. Lens Driver ICs for camcorder and camera - Industrial Devices Solutions - Panasonic. A Dual H-Bridge Motor Driver IC The 17C is a SMARTMOS compact monolithic dual channel H-Bridge power IC, ideal for portable electronic applications containing bipolar stepper motors or brush DC motors such as those used in camera lenses and shutters. The 17C can operate efficiently with supply voltages from V. Description. The MAX high-voltage liquid lens driver features a high-voltage differential output controlled through an I²C interface. The MAX uses a charge-pump-based boost converter and integrated H-bridge to provide a compact lens driver solution with minimal external components to achieve a small overall footprint suitable for small space constraints inside camera modules.

Lens Driver Components Analog Devices offers a range of lens driver solutions for camera modules in camera phones, camera enabled handsets, DSCs, consumer entertainment, and computer imaging. Lens drivers integrate drivers, waveform control, power management, signal processing, travel control, and more to provide the smallest, lowest power, most complete system solutions with the latest motor/actuator technologies. The DRVA is an advanced voice coil motor driver for camera auto focus. It has an integrated D/A converter for setting the VCM current. VCM current is controlled with a fixed frequency PWM controller or a linear mode driver. Current generation can be selected via I 2 C register. Lens Driver ICs for camcorder and camera Allow smaller mounting area by dramatically reducing the external parts Allows low power consumption of iris drive by adopting the PWM.

We provides a lineup of lens driver ICs that enable a zoom and focus control and iris control automatically. We also provide driver ICs driving various. technology integrates: a piezo motor, drive IC, digital Hall position sensor IC, low-friction preload mechanism, precise lens guide, and advanced Smart. Its driving circuitry is very compact because of the availability of a customized driver chip from Maxim Integrated Products (see Figure 4). Auto-focus.
