General Purpose: Sensor IC Selection Lineup Catalog 2011

ROHM Semiconductor released Sensor overview with following headlines:
Hall ICs – Ambient Light Sensor ICs – Temperature Sensor ICs – Sensor Backend ICs

Hall Sensor IC Series
ROHM Hall ICs integrate a highly sensitive Hall element on a single chip that can perform open/close switch operations through magnetic field detection. This contactless method increases reliability by eliminating failures due to repeated switching or the introduction of foreign objects. Five series are offered, making it possible to select the optimum solution based on set requirements.

Ambient Light Sensor IC
ROHM ambient light sensor ICs can measure a broad illuminance range from darkness to day light. It provides illuminance data for adjusting LCD backlight brightness of electricity, in order to decrease current consumption of the application and increase visibility. Both analog and digital output type are available.

Temperature Sensor IC
The ROHM temperature sensor IC series is integrating a sensor element, current source circuit and high accuracy reference voltage source into a single chip. This product series will reduce circuit design complexity and can be used in several electrical applications that need temperature detection; e.g. mobile phone, PC, LCD TV, industrial machine, game, car navigation  etc.

Sensor Backend IC
The ROHM Sensor backend ICs integrate several functions into a single chip, allowing an optimal system implementation for each sensor. IrDA controller IC and IC for human body detector sensor are in line-up. ROHM can help to add a sensor function to implement higher functionality and energy saving.
