TI beefs up sensing solution with Hall-effect sensors
Texas Instruments has updated its sensing portfolio with the addition of "Hall effect" magnetic sensors designed for industrial applications ranging from position detection to motor control. The Hall Effect is used to detect the presence of a magnetic field by an induced change in the electric field.
The DRV5000 series includes digital latch, digital switch, digital omnipolar switch, and analogue bipolar output options. The series features reverse supply protection up -22V, and the ability to withstand transient voltages up to 40V. It supports operation in temperatures ranging between -40°C and 125°C with minimal change in magnetic sensitivity.
In addition to the new Hall effect sensor family, TI introduced two new reference designs to provide solutions for motor control: the "12V and 24V Brushless DC Outrunner Motor" and the "Speed-Controlled 24V Brushless DC Outrunner Motor" reference designs. The latter specifies a gate driver with closed-loop speed control to maintain accurate revolutions per minute across the entire motion profile.
The DRV5000 series is available to sample in industry-standard SOT-23, 3pin surface mount and TO-92S, 3pin through hole package options. The highest sensitivity digital latch device (DRV5013) is currently in production.
