Atmel's New BCDMOS Dual-Output Flasher IC with Functional LED Control Targets Next-Generation Flasher Systems

10/16/2002 - Atmel® announced the availability of a new BCDMOS Flasher IC, the ATA6140. In contrast to standard Flasher ICs, the ATA6140's dual output enables to additionally control the LED array. With this extended functionality, the new Flasher IC is tailor-made for industry's latest generation of Flasher systems that provide LED control for the very first time. The ATA6140 is manufactured on Atmel's 0.8-micron BCDMOS process technology, which supports operation of up to 40 Volts. This technology is optimized for applications in harsh environments. The device is especially designed for low-power applications and high EMI requirements in the 12-V and 24-V power net.

The ATA6140 Flasher IC includes 2 inputs (high/low active) for right and left control, plus an additional 2 inputs for LED array outage control (right and left side). Out of the overall 4 inputs, one input per side has the option to be either high active or low active. Due to this, less external components are needed, which speeds-up design-ins and helps to reduce costs. Compared to conventional Flasher ICs, the ATA6140 with its various inputs is much more flexible, competing solutions that aim to achieve comparable flexibility need to integrate additional components.

Furthermore, the ATA 6140 incorporates hazard input, two separate output stages, sleep mode and protection features, which meet stringent automotive requirements. The output stages are designed to meet high current capability and low saturation voltage.

"Atmel, a world leader in the Flasher IC mass market, addresses with this new low-power dual-output Flasher IC the new Flasher systems with LED control", said Torsten Mann, Marketing Director for Automotive and Control products at Atmel. "Due to its various inputs, our new ATA6140 provides maximum flexibility and helps to bring down costs."

The ATA6140 provides full protection against short circuits. In case of undervoltage or overvoltage, the output stages will be switched off. The device also meets the strict automotive qualification demands (protection against conducted interferences, EMC and 2 kV ESD protection) and withstand transients according to ISO/TR 7637/1.

Samples of the new BCDMOS flasher IC ATA6140 in SO16 package are available now. Pricing starts at US$ 0.96 (10 k).
