ROHM Semiconductor, in collaboration with its affiliated company, OKI Semiconductor Co., Ltd., today announced the launch of a dedicated Large Scale Integrated (LSI) circuit family designed to support the Intel® Atom™ processor E6xx series (formerly code-named Tunnel Creek). This chipset consists of a power management IC (PMIC), a clock generator IC (CGIC) and an input/output hub (IOH) IC. A reference board that simplifies customer development...

The new high-performance, high-reliability stepper motor drivers from ROHM Semiconductor offer selectable excitation modes—full-step to sixteenth-step with 1.0A or 2.0A output current and full-step to eighth-step with 2.5A output current. These microstep drivers enable designers to optimize motor torque, noise and vibration for a wide range of applications. Selectable current decay pattern (FAST/SLOW/MIXED decay modes) further enhances motor pe...

The new ECOMOS series of P-channel and N-channel MOSFETs from ROHM Semiconductor are designed to meet the prescribed operation at lower gate drive voltages that emerging generations of portable electronic devices require.

ROHM Semiconductor has introduced a new series of CMOS LDO regulators featuring ROHM’s proprietary automatic power-saving (APS) function that dynamically switches performance characteristics based on operating conditions. The BHxxPB1 Series combines the benefits of LDOs — small packaging, minimal external components and simple design process — with very low average power consumption.

ROHM Semiconductor has announced a new family of analog and digital Ambient Light Sensor (ALS) ICs for the efficient control of LED backlighting for LCD-equipped devices. Featuring ROHM's proprietary trimming process and use of multiple photodiodes with different junction depths, the ALS ICs provide an accurate output with little variation between various light sources. The spectral response of ROHM ALS ICs has been tailored to closely match tha...
