Datasheet Summary with AI

️· Battery-critical position sensing

## Description
The TMAG5131-Q1 is an ultra-low power, high precision Hall effect sensor for automotive applications. It offers multiple magnetic thresholds, sampling rates, and output types. It operates with both North and South magnetic poles and has low current consumption. It is available in an industry-standard SOT-23 package and operates from -40°C to 125°C.

## Specifications

️· Absolute Maximum Ratings: See datasheet for specifics (VCC, Output Voltage/Current, Magnetic Flux Density, Temperature)
️· Electrical Characteristics: (VCC = 1.65V to 5.5V) Includes values for Output Leakage, Low Level Output Voltage, High Level Output Voltage, Frequency of Magnetic Sampling, Average/Peak Current Consumption.
️· Magnetic Characteristics: Includes values for Magnetic Threshold, Release Point, Hysteresis.
️· Thermal Information: Provides values for Junction-to-Ambient thermal resistance.

## Functional Description
The device features a Hall effect element, analog signal conditioning, and a low-frequency oscillator. It periodically samples the magnetic field and updates the output, entering a low-power sleep state when no change is detected. The output can be either push-pull or open-drain.
