Product details

Automotive-grade Hall-effect current sensing

80 kHz bandwidth — what it buys the power-stage designer

With an 80 kHz bandwidth and a 6.5 µs response time, this sensor tracks fast current transients in switching power converters and motor-phase loops. Linearity of ±0.05% keeps the transfer curve clean across the measurement span, reducing the need for multi-point calibration in production.

Supply and output — single-rail simplicity

The ratiometric voltage output tracks the supply, so the full-scale output scales with the ADC reference — a useful feature when the same rail feeds both the sensor and the microcontroller.

For volume production or BOM-line qualification, the AEC-Q100 certification and automotive grade are already documented, so no additional qualification paperwork is needed for tier-one programs.

Frequently asked questions

Does TMCS1100A3QDRQ1 measure AC and DC?

Yes, the Hall-effect sensing element responds to both AC and DC current. The ratiometric voltage output tracks the instantaneous current waveform, so the sensor works for DC bus monitoring, AC line sensing, and switched-current waveforms within the 80 kHz bandwidth.

Is TMCS1100A3QDRQ1 AEC-Q100 qualified?

Yes, the TMCS1100A3QDRQ1 is AEC-Q100 qualified and carries an Automotive grade. This covers the qualification requirements for most automotive ECU and module programs without additional stress testing.
