US91AEVK-AAA-000-SP

Overview

The US91AEVK-AAA-000-SP is a two-coil fan driver from the Melexis US91A series, designed for brushless DC motor control. It operates on a supply voltage range of 4.7 V to 30 V and supports load voltages of 12 V and 24 V. The device features an output current capability of 20 mA with a maximum output voltage of 100 V. It functions within a temperature range of -40°C to +125°C and utilizes a SOT-23-5 surface-mount package.

Feature Summary

Integrated Hall effect sensor for commutation
Two-channel output driver structure
Open/switch interface control

Applications

Fan motor drivers
Brushless DC motor applications
Blower systems

Procurement Notes

Verify the specific suffix 'VK' against the official datasheet to confirm pinout and functional compatibility, as suffixes often denote package or tape-and-reel variations. Confirm availability status, as this part may be subject to production lifecycle changes or limited stock constraints depending on the distributor.

Selection Notes

Select this component for low-power fan applications requiring simple open-loop or switch-based control. Ensure the required output current does not exceed 20 mA. Verify that the system operating temperature falls within the specified -40°C to +125°C range and that the supply voltage aligns with the 4.7 V to 30 V input specification.

Part Context

This part belongs to the US90A/US91A family of integrated fan drivers. These devices combine Hall sensing and power driving in a small footprint, simplifying design for small fans and blowers by eliminating external components typically needed for commutation and drive stages.
