Frequently Asked Questions
How much isolation voltage does the TMCS1107A2UQDT provide between current path and signal output?
The TMCS1107A2UQDT provides 420 V of galvanic isolation between the current-carrying conductors and the analog signal output pins. This isolation level protects low-voltage microcontrollers and signal processing circuits from high-voltage transients in motor drive and power inverter applications operating at mains potentials.
For a motor drive design, how does the TMCS1107A2UQDT output a current-proportional signal?
The TMCS1107A2UQDT outputs an analog voltage proportional to the sensed current, scaled around an internal midpoint reference voltage of approximately VCC/2. At a 5 V supply, the output swings from 0.5 V to 4.5 V across the measurable current range, enabling direct connection to a microcontroller 10-bit or 12-bit ADC input for closed-loop motor current control.
Is an external shunt resistor or filter capacitor required when using the TMCS1107A2UQDT?
No external shunt resistor is required since the TMCS1107A2UQDT uses Hall-effect sensing through the integrated current path conductors. The internal voltage reference also eliminates the need for an external reference, though a small decoupling capacitor of 100 nF on the VCC pin is recommended to filter supply noise and ensure stable analog output in high-frequency switching environments.
Which industries use the TMCS1107A2UQDT, and what current ranges does it measure?
The TMCS1107A2UQDT is used in industrial motor drives, EV charging infrastructure, solar inverters, and UPS systems. Depending on the variant suffix, it measures current ranges suited to tens of amperes, with the internal Hall sensor providing linear response across positive and negative current directions, enabling bidirectional AC and DC current measurement from a single 5 V supply.
