Key Features
- ±420 V basic isolation rating with 20 A RMS continuous current measurement capability for AC and DC motor drive current sensing
- 80 kHz analog output bandwidth enables real-time current feedback in fast-switching inverter and power converter control loops
- Hall-effect galvanic isolation eliminates shunt resistor power loss and provides inherent high-voltage protection in an 8-pin SOP package
Applications
The TMCS1107A2BQDR is designed for non-contact AC and DC current sensing in motor drives, servo amplifiers, and solar inverters where galvanic isolation from high-voltage bus rails up to ±420 V is required for safety and accuracy. Its 80 kHz bandwidth supports fast current-loop control in switched-mode power converters and variable-frequency drives operating at switching frequencies up to several tens of kilohertz. The analog voltage output integrates directly with ADC inputs on DSPs and microcontrollers, making it suitable for three-phase inverter current feedback, battery current monitoring, and overcurrent protection circuits.

Frequently Asked Questions
What isolation voltage and continuous current rating does the TMCS1107A2BQDR provide?
The TMCS1107A2BQDR provides basic isolation rated at ±420 V and supports 20 A RMS continuous current measurement. This isolation level protects the control-side circuitry from high-voltage motor bus rails or mains-connected power stages, eliminating the need for external current transformers or shunt resistors in isolated power electronics designs.
How does the 80 kHz bandwidth of the TMCS1107A2BQDR benefit motor drive current control loops?
The 80 kHz analog output bandwidth of the TMCS1107A2BQDR enables accurate current waveform reproduction up to the 80th harmonic of a 1 kHz fundamental, supporting current-loop bandwidths of 10 kHz to 20 kHz in vector-controlled motor drives. This bandwidth is sufficient for real-time overcurrent detection within a single PWM cycle at switching frequencies of 16 kHz to 20 kHz in IGBT and SiC MOSFET inverter stages.
How does using TMCS1107A2BQDR compare to a shunt resistor for current sensing in a 20 A motor drive?
A shunt resistor in a 20 A motor drive dissipates I²R power continuously — at 5 mΩ it wastes 2 W — while the TMCS1107A2BQDR's Hall-effect sensor adds negligible series resistance, eliminating that loss. The TMCS1107A2BQDR also provides ±420 V galvanic isolation, which a shunt resistor requires an additional isolation amplifier to achieve, simplifying the signal chain by removing at least one additional IC from the design.
What output signal does the TMCS1107A2BQDR provide and how is it connected to a microcontroller ADC?
The TMCS1107A2BQDR outputs an analog voltage proportional to the measured current, centered at a 2.5 V midpoint for bidirectional measurement with a sensitivity of approximately 100 mV/A. This signal connects directly to a 12-bit or 16-bit ADC input on a microcontroller or DSP operating from a 5 V or 3.3 V supply, with the ADC reference voltage and gain set to match the ±2.5 V output swing for 20 A full-scale measurement.
