Hall Effect sensor ics offer high sensitivity
Honeywell has introduced two Hall Effect sensor ics for brushless motor designs.
The SS360PT and SS460P are suited to cost sensitive, high volume applications such as flow rate sensing, speed and RPM sensing, tachometers, motor and fan controls.
They offer a high magnetic sensitivity of 30Gauss typical at 25°C, and 55Gauss maximum over the full -40 to 125°C temperature range, allowing for the use of smaller magnets or a wider air gap.
The ics do not use chopper stabilisation on the Hall element, providing a cleaner output signal and a faster latch response time compared to similar designs.
The SS360PT is available in a sub-miniature, SOT-23 surface mount package with automoated component replacement, while the SS460P comes in a flat TO-92-style package, allowing for a compact pc board layout design.
