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.
The current-switching output technique allows for the reduction in cost in the wiring harness because only two connections to the device are required. The current-switching output structure also inherently provides more immunity against EMC/ESD transients. These devices have low...
