The 80 kHz bandwidth captures switching-frequency content from motor drives and power converters, while the 6.5 µs response time keeps the signal path fast enough for overcurrent detection thresholds. Operating from a 3 V to 5.5 V supply, the output swing matches the input range of common 3.3 V and 5 V ADCs without an external level shifter. The bidirectional polarization means the output sits at half-supply with zero current and swings up or down depending on current direction — no need for a separate reference voltage. ## Industrial temperature grade and SOIC-8 footprint Rated for -40°C to 125°C ambient, the TMCS1101A3BQDT suits motor-drive enclosures, HVAC compressor bays, and outdoor telecom rectifiers where the board sees sustained heat. The 8-SOIC package (3.90 mm body width) is a standard footprint that routes the current-carrying traces through the leadframe — the low 6 mA max supply draw keeps self-heating negligible. Linearity of ±0.05% means the transfer function from sensed current to output voltage deviates less than one LSB in a 12-bit system over the full ±11.25 A range, so calibration tables stay simple. The single-channel, ratiometric output eliminates the gain drift error that fixed-reference sensors introduce when the supply rail moves.","metaTitle":"TMCS1101A3BQDT Hall-Effect Current Sensor, ±11.25A","metaDescription":"Texas Instruments TMCS1101A3BQDT Hall-effect current sensor, ±11.25A, ratiometric voltage output, 200 mV/A, 80 kHz bandwidth, 8-SOIC.
