Description
A5940KLKTR-T Three-Phase Sensorless Fan Driver
The A5940KLKTR-T is a three-phase sensorless sinusoidal fan driver for brushless DC fan and blower designs. This K-temperature variant supports an ambient range of -40°C to 125°C and uses a thermally enhanced 10-lead SOIC package.
What A5940KLKTR-T Is Designed to Do
The A5940KLKTR-T is a three-phase sensorless sinusoidal fan driver for brushless DC fan and blower designs. This K-temperature variant supports an ambient range of -40°C to 125°C and uses a thermally enhanced 10-lead SOIC package. Final suitability depends on the complete circuit, software, thermal, mechanical, qualification and lifecycle requirements.
For sourcing, the base family name is not enough. The full A5940KLKTR-T ordering code, package, packing format, revision or grade, source condition and required inspection evidence should be confirmed against the actual order.
