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 newest members to the ML610Q4xx series of low-power microcontrollers from LAPIS Semiconductor (formerly OKI Semiconductor) will give designers even more choices when creating products that provide comprehensive control over the operation of battery-powered devices used for the measurement and display of temperature, humidity and carbon monoxide (CO) in industrial and commercial environments. These new devices feature an RC-type analog-to-digi...

OKI Semiconductor (part of the ROHM Group) is developing a new memory technology called ferroelectric RAM (FeRAM). This new series will amend the memory line-up of the ROHM Group, which already consists of EEPROM, DRAM and P2ROM and is presented at PCIM in Nuremberg (May 17-19, Hall 12, Booth 480).

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...

ROHM Semiconductor has expanded its widely used lineup of high speed switching, high voltage resistance MOSFETs for PFC circuits in switching power supplies and main switch circuits. A variety of package types are available in both, surface mount (i.e. CPT/D-PAK, LPT/D2-PAK) and through-hole (e.g. TO-3PF) configurations. The new series, truly lives up to its name PrestoMOSTM, as it features low trr characteristics for high speed, high speed switc...

ROHM Semiconductor GmbH has recently announced the development of two types of high-bright RGB LEDs: SMLV56RGB1W1, featuring a height of only 0.6mm, and the standard-type SMLW56RGB1W1, featuring a height of 1.1mm. Both units are capable of 1.8cd (white).

A ranking of the 1Q12 top semiconductor suppliers is included as part of IC Insights' soon-to-be-released May Update to The McClean Report. Intel remained firmly in control of the number one spot in the ranking. In fact, Intel extended its lead over second-ranked Samsung by registering a 68% higher sales level than Samsung in 1Q12 as compared to a 48% margin for all of 2011.

ROHM, in collaboration with Ritsumeikan University and Information Services International – Dentsu, Ltd., recently announced Guidepost Cell, a unique indoor location detection infrastructure that supplies highly precise positional data to smartphones and other mobile devices to determine a user’s location inside buildings, underground malls and other interior areas using low-power 802.11-compliant wireless beacon protocol.

ROHM Semiconductor unveiled its new high power, high brightness white chip LED SMLx family with reflector (PLCC2 & high heat radiation packages) for automotive backlighting applications. Today, the increased functionality of clusters, car audio & navigation, climate control, switches and LCD/TFT backlighting create a high demand for efficiency while also relying on constant light emission, power saving and stability. With its new LED and LED driv...

ROHM has developed the BD7xxL2EFJ-C series of high-voltage (50V) LDO regulators for automotive applications featuring the industry’s lowest dark current* (6μA) – 80% lower than conventional LDO regulators – utilizing a proprietary circuit design, reducing power consumption significantly.
