The ATS673 and ATS674 are high performance Hall sensors. They have compact dimensions, low power consumption, high immunity and high accuracy. These devices are specifically designed for automotive applications and are able to withstand the effects of radiated and conducted transients.
The ATS673 and ATS674 are single-chip, true zero-speed (TPOS) gear tooth sensors designed specifically for automotive cam sensing. They feature a sophisticated digital circuit that eliminates magnet and system offsets, providing high immunity to vibration and air-gap independence. The devices utilize a True Power-On State (TPOS) function to ensure accurate detection of teeth and valleys regardless of the initial power-on position.
