TITMCS1101A2UQDRQ1
Overview
The TMCS1101A2UQDRQ1 is a high-precision, AEC-Q100 qualified Hall-effect current sensor designed for automotive applications requiring galvanic isolation. This unidirectional sensor provides a ratiometric analog output with 100mV/A sensitivity and 80kHz bandwidth, making it suitable for monitoring AC or DC loads with high accuracy. It features internal electrical shielding to minimize interference from high-voltage switching transients.
Why Choose This Part
This sensor offers exceptional linearity of +/-0.05% and a zero-drift internal reference, ensuring stable performance across the -40C to 125C operating range. The 600V lifetime working voltage and functional safety-capable designation make it a robust choice for critical automotive power electronics.
Applications
Key Specifications
Getting Started
To evaluate this part, use the TMCS1101EVM evaluation module which provides a test fixture for measuring current up to the full-scale range. Integration requires an analog-to-digital converter (ADC) to read the ratiometric voltage output, typically referenced to the same VCC supply as the sensor to minimize gain errors.
