A1242 Two-Wire Chopper-Stabilized Hall Effect Latch Features and Benefits ▪ Chopper stabilization ▫ Superior temperature stability ▫ Extremely low switchpoint drift ▫ Insensitive to physical stress ▪ Reverse battery protection ▪ Solid-state reliability ▪ Small size ▪ Robust EMC capability ▪ High ESD ratings (HBM) Packages: 3 pin SOT23W (suffix LH), and 3 pin SIP (suffix UA) Description The A1242 Hall effect latch is a two-wire latch especially suited for operation over extended temperature ranges, from –40 to +150°C. Superior high-temperature performance is made possible through the Allegro dynamic offset cancellation technique, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.
