Dual-Photodiode with a common anodePREMA IC PR5010PR5010 is a double silicon photodiode with two symmetrical anodes and a common cathode, sensitive for visible light. The cathode forms an additional photodiode to the substrate that is sensitive for infrared light.
Sensor IC for centre detection of a light sourcePREMA IC PR5510
PR5510 can detect the lateral position of a light spot on the sensor. It consists of triangular photodiodes with reciprocal orientation, together with a differential transimpedance amplifier. If illuminated uniformly, the output is Vcc/2; if the light is biased towards one of the triangles, the output i...
PR5201-TM low-cost solution for -40 to +85°C (NEW!)
PR5201-OC for -40 to +125°C (NEW!)
PREMA PR5101 and PR5201 Photosensor ICs for Optical Quadrature Encoders can be used in a wide range of encoders. They excel with quick assembly, high resolutions without interpolation, an innovative method to produce a sharp Z (index) pulse, and high performance of photocurrent amplifiers allowing a low LED current.
The high voltage operational amplifier PR2202 works for supply voltages of up to 80V single supply or up to ±40V and a maximum output current of ±6mA. The temperature increase of the component remains small in spite of the high voltages due to the low quiescent current of only 500µA.
PREMA Semiconductor's Dual Photodiode PR5001 is a dual-element Si photodiode moulded into a small plastic leadless optical package. The photodiodes offer a very good symmetry, low dark current and high sensitivity.
PR4101 is a buckdriver for up to 40V input voltage. Its versatility and its dimming input make it ideal for halogen lamp replacement and general lighting. PR4101 is offered in SO-08 and SO-14 package, as well as a smaller variant in a tiny SOT23-5L package. Versatility and high power are key features of these LED drivers, which can also be used as proven standard cells in an ASIC project.
PR4401 andPR4402 are LED boost converters in a tinySOT23 package that drive white LEDs from a single battery cell. Output currents of 20mA (PR 4401) and40mA (PR 4402) can be achieved. The only other component needed is an inductor. A cleverly devised control circuit produces a constant output current. Maximum performance at minimum space and cost is the goal of this smart IC.
PR4403 drives and controls white LEDs out of one single battery charged by solar cells.

PREMA Semiconductor is exhibiting at electronica in Munich from Nov. 14-17, 2006. See us at: Hall A4, Booth A4-406.
The core of the new driver PR4401 consists of a step-up converter with current output, that provides an output voltage of typically 3.6V for white LEDs. The input voltage can be as low as 0.9V, thus allowing a single cell battery operation.
Standard light sources such as bulbs are replaced by LEDs or LED strings in more and more applications now. The ASIC manufacturer PREMA Semiconductor offers the new constant current driver PR4130 controlling up to three LEDs in series.
For the application in custom specific ICs, PREMA Semiconductor GmbH has designed the new high voltage operational amplifier OP601VHV for supply voltages of up to ±60V or up to 120V single supply.
