Hall-effect Latched Sensor BDH8181 Designed for Electronic Commutation of Brushless DC Motor Applications

PublishTime： 2024-01-23 Article Source：BD MCRIO News

The BDH8181 is an integrated Hall-effect latched sensor designed for electronic commutation of brushless DC motor applications.

The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt to provide switching hysteresis for noise rejection and open-collector output.

An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.

A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF.

This IC is available in the TO-92S-3 and SOT-23-3 packages.
