Product details
Overview
R2J30516LG#U0 from Renesas Electronics is a highly integrated lens motor driver IC for optical image stabilization (OIS) and autofocus in smartphone and compact camera modules, featuring a built-in H8S/2600 16-bit MCU core, dual-channel OIS H-bridge drivers, six-channel lens drivers (expandable to seven), 12-bit ADC, and 512-step micro-stepping PWM control. It supports gyro sensor interface via digital I/F and operates with 1.8V regulator compliance.
For engineers reviewing the R2J30516LG#U0 datasheet, R2J30516LG#U0 pinout, R2J30516LG#U0 application, or R2J30516LG#U0 equivalent, key selection considerations include OIS servo loop performance, multi-VCM channel count, micro-step resolution for silent actuation, ADC resolution for position sensing, and LGA-100 package compatibility with high-density camera module layouts.
Technical Context
The R2J30516LG#U0 integrates a dedicated MTD_DSP core alongside the H8S/2600 CPU for real-time OIS servo control and adaptive digital filtering, enabling sub-millisecond response to gyro input. Its dual OIS channels support independent VCM driving with high-speed PWM and fine 512-step micro-stepping for jitter-free correction.
It provides six standard lens driver channels (extendable to seven in exclusive mode), each capable of high-speed PWM output, plus on-chip 12-bit ADC for closed-loop position monitoring and 8-bit DAC for analog sensor interfacing. The device includes SPI/I²C, UART, CSIO, and GPIO peripherals for system integration with host processors and sensors.

This capability is confirmed in Renesas' system block diagram and functional description for the R2J30516LG#U0.
How many lens driver channels does the R2J30516LG#U0 support, and what is their operational mode?
The R2J30516LG#U0 supports six standard lens driver channels for AF, zoom, iris, ND, and shutter VCMs, with an exclusive control mode enabling a seventh channel. All channels deliver high-speed PWM output up to 1 MHz and feature 512-step micro-stepping for silent actuation. This configuration is documented in Renesas' functional overview and system block diagram for the R2J30516LG#U0, confirming its use in complex multi-actuator camera modules.
What package type and dimensions does the R2J30516LG#U0 use?
The R2J30516LG#U0 uses a 100-pin LGA (Land Grid Array) package measuring 5.5 mm × 5.5 mm with 0.5 mm pin pitch and 1.05 mm maximum height, per Renesas package drawing PT-LG0100KA-A. This compact, low-profile package is engineered for high-density camera module PCB stacking and thermal management in slim mobile devices - a key specification confirmed in the official Renesas outline documentation for the R2J30516LG#U0.
