Diodes Corporation (Nasdaq: DIOD) has launched a new high sensitivity Hall effect sensor product portfolio. The powerful AH39xxQ series devices provide accurate speed and direction data or two independent outputs. These sensors are designed specifically for industrial and automotive product applications, detecting rotation and linear speed/direction, as well as determining the angular position of the rotation axis.
The AH39xxQ series Hall effect sensors meet the requirements of automotive batteries and can operate in a wide supply voltage range of 2.7V to 27V. They have an absolute maximum rating of 40V and can safely handle a 40V load dump. In addition, the -18V reverse voltage protection function can prevent incorrect battery connections. To enhance stability, these devices provide electrostatic discharge (ESD) protection that exceeds the automotive specifications of 5kV human body models (HBM) and 2kV charging device models (CDM).
Three typical values of BOP/BRP are available for selection, namely 10/-10 Gauss, 25/-25 Gauss, and 75/-75 Gauss. The narrow operating window ensures accurate and reliable switching points. Dual channel operation means that these sensors can replace two latch switches, thereby reducing PCB space and overall component costs. Due to the combination of chopper stable amplifier and advanced Hall board design, this device can reduce switch point drift and ensure accurate measurement over a wide temperature range.
The self diagnostic function of AH397xQ is suitable for systems that comply with ISO 26262 specifications. If the device detects faults such as overheating or undervoltage locking, it will enter a safe operation mode, which is more reliable.
The Diodes AH39xxQ series Hall effect sensors comply with the AEC-Q100 Grade 0 specification, are manufactured by IATF 16949 certified facilities, and support PPAP files. These products are supplied in TSOT25 packaging. The above models and the complete product combination of Hall effect sensors are included in the Hall effect sensor parts selector.
