Allegro MicroSystems ATS675LSE
The ATS675 is a next generation member of the Allegro True Power‑On State (TPOS) sensor IC family, offering improved accuracy compared to prior generations, and performing at absolutely zero target speed. The device incorporates a single Hall-element IC with an optimized custom magnetic circuit that switches in response to magnetic signals. The resulting output of the device is a digital representation of a ferromagnetic target profile.| Part No. | ATS675LSE |

APPLICATIONS
FEATURES AND BENEFITS
● Optimized for automotive camshaft sensing● True target state recognition at device power-on (TPOS) and at zero target speed
● Chopper stabilization reduces offset drift
● Digital output polarity option: follow or invert target profile
● Rapid calibration and transition to Running mode
● Automatic Gain Control (AGC) during calibration eliminates effects of air gap variations
● Tight timing accuracy over full operating temperature range
● Operation at supply voltages as low as 3.3 V
● Undervoltage lockout (UVLO) PACKAGE: 4-pin SIP (suffix SE) Not to scale
DESCRIPTION
An output polarity option allows customization for specific applications. The IC contains a sophisticated digital circuit designed to eliminate the detrimental effects of magnetic and system offsets. Signal processing is used to provide target state recognition at zero rotational speed, consistent switch points regardless of air gap, and dynamically adapt device performance to the typical operating conditions found in automotive environments, particularly cam sensing applications.
