The ROHM Electronic Laboratory is now up and running. It’s an interactive simulation tool for designing circuits and evaluating characteristics. Currently, the ROHM Electronic Laboratory is available for switching regulators and H-bridge drivers.

1. Verify and evaluate characteristics and operation
2. Customize the number and type of external components
3. Adjust the input signals
4. Create a parts list after simulation

ROHM Semiconductor offers a range of LED drivers commonly used in mobile and LCD backlight products and a variety of LED illumination applications. The drivers listed here are for driving high current, high brightness LEDs including the Cree XLamp LED® series that are lighting the industry with efficient environmentally friendly LED light.

ROHM ambient light sensor (ALS) ICs are designed to control the brightness of LED-backlighted LCD displays based on ambient light availability and brightness for optimum display visibility and energy efficiency. The compact ROHM ALS ICs are the ideal choice for LCD-equipped portable devices as well as LCD monitors and high-definition (HDTV) backlighting control.

The demands for extended battery operation, greater reliability and increased features are driving the designs of mobile phones, notebook computers, video cameras, navigation systems and game controllers to use smaller, higher performance components.

ROHM H-bridge drivers offer a simple solution for pulse-width modulation (PWM) motor speed control using either the built-in PWM generator to convert analog inputs or TTL compatible logic-level inputs from an MCU.
