Southchip launches SC3606 driver chip for piezoelectric cooling fans
Overview
Southchip has launched the SC3606, a driver chip for piezoelectric fans, according to Pandaily.
The 2.3mm by 2.75mm chip accepts 2.1V to 5.5V input and outputs up to 46Vpp across 2kHz to 40kHz. It tracks resonance in real time to find the operating point. Pandaily reports the fans can be under 1mm thick and run at around 30dB. Southchip says it believes piezoelectric fans are one of the best fits for thin devices such as smartphones. Southchip has not named any device that will use the chip.
