Called AH39xxQ, “they also have a 40V absolute maximum rating, enabling them to safely handle 40V load dumps”, according to the company. “Additionally, -18V of reverse voltage protection guards against incorrect battery connections. For added robustness, the ESD [electrostatic discharge] protection exceeds the automotive norms of 5kV HBM [human body model] and 2kV CDM [charge device model].”
The devices operate over 2.7V to 27V (4.7mA) and -40 to +150°C, and are packaged in 3 x 3mm TSOT25.
Each has two sensors built in 1.45mm apart, and they are largely intended to work with quadrature-style magnetic fields.
