Diodes Incorporated has introduced the AH396x, a high-voltage dual Hall effect sensor designed for applications that require accurate speed and direction sensing. To support a wide range of demanding applications, the device is optimized to operate over the supply range of 2.7 V to 27 V.
The AH3965/66/67 provides speed and direction outputs with chopper-stabilized architecture and an internal bandgap regulator to provide a temperature-compensated supply for internal circuits. The AH3968 provides two independent outputs in Q1 and Q2.
For robustness and protection, the devices have a reverse blocking diode with a Zener clamp on the supply voltage. If the supply voltage falls too low, the undervoltage lockout protection is triggered, freezing the IC and preventing any incorrect magnetic measurement.
All the devices are available in the industry standard TSOT25 (Type A1) package.
