Semtech Ramps Production of Load Switches for the Automotive Industry

New FemtoSwitch™ specifically used for new smart-keys in vehicles to preserve battery life

Camarillo, California - July 11, 2017 -

Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced the availability of a new load switch in its FemtoSwitch™ product family. The new ultra-low-Ron (32mΩ) load-switch is critical in improving power performance by maintaining a negligible voltage drop when the switch is turned on.

The new addition extends Semtech’s FemtoSwitch family of high-performance analog load switch ICs with the automotive qualified capability. It offers a very low Quiescent Current (1uA) and Shutdown Current (300nA), ideal for preserving the battery life of certain products such as automotive smart-keys. For higher reliability, the electrostatic discharge (ESD) capability has been hardened to 4kV which is beyond the industry standard.

“Consumers are demanding more ease and functionalities in their products including smart-keys,” said Francois Ricodeau, Product Line Manager for Semtech’s Power and High-Reliability Products Group. “By adding the new automotive qualification to FemtoSwitch, Semtech is positioned to meet the industry and consumer trends and demands.”

Key Features of the New FemtoSwitch

• Automotive AEC-Q100 (Grade 3) qualified

• Provides extremely low on-state resistance

• 2A continuous output current

• Over temperature protection • Hardened ESD protection

• Ultra-small 0.9 x 0.9 mm package
