New Cypress Automotive LED Driver for Headlight Systems

Cypress Semiconductor Corp. recently introduced an automotive LED driver that enables smaller headlight systems. The S6BL112A automotive-grade LED driver features synchronous control, enabling stable performance in a lighting system. The device is able to drive LEDs at a 2.1-MHz switching frequency, reducing physical size and costs. The LED drivers combine with Cypress's Traveo microcontrollers (MCUs) and power management ICs (PMICs) to provide an automotive front-lighting solution.

Cypress's S6BL112A Automotive LED driver features an input voltage range of 4.5-42 V that encompasses operating conditions such as cold-cranking or load dump. The LED driver also facilitates the design of electrical system safeguards by including System Safety Functions such as under current detection, over current and voltage protection, as well as the ability to mask LED OPEN diagnosis during cold cranking. Its synchronous operation eliminates unstable dimming that can occur when the input voltage is low.

The new S6BL112A LED driver is currently sampling, with production expected in the fourth quarter of 2016. It is available in a 16-pin, thermally-enhanced TSSOP package.

More information on Cypress's automotive LED drivers is available on the company's website.

HexaTech Demonstrates UVSure UV-C LED

HexaTech Inc. announced the demonstration of its UVSure UV-C LED, based on HexaTech's proprietary aluminum nitride (AlN) substrate material. The 263 nm wavelength device achieves 6 mW in a 0.15 mm2 active area die. When scaled to their second generation footprint, the die is expected to produce approximately 24 mW.

When driven in pulse mode to 300 mA, the same 0.15 mm2 active area die is able to reach 19 mW, or approximately 76 mW in the large die format.
