What are the key features of TMCS1107A3UQDR?

420 V reinforced isolation with CMTI >100 kV/µs for high-voltage rail current sensing
Internal voltage reference delivers ratiometric analog output with 18.75 mV/A sensitivity
Wide -40°C to 85°C operating range in compact 8-SOIC package for industrial designs

What is TMCS1107A3UQDR used for?

The TMCS1107A3UQDR is designed for industrial power monitoring, motor drive systems, and solar inverters where galvanic isolation between the high-voltage bus and control circuitry is required. Its 420 V isolation rating suits grid-connected equipment and three-phase drives operating from 200 V AC mains. Engineers also deploy it in battery management systems and DC/DC converters to measure charge and discharge currents with precision analog output.

Frequently Asked Questions

What isolation voltage does the TMCS1107A3UQDR support and what does that enable in a design?

The TMCS1107A3UQDR provides 420 V reinforced isolation between the current-carrying conductors and the signal output, with a CMTI rating exceeding 100 kV/µs. This allows a 3.3 V microcontroller to safely measure currents on a 200 V AC bus or a 400 V DC link without opto-isolators or transformer-based isolators, simplifying the bill of materials and reducing board space by at least 40%.

Which motor control or inverter designs can use TMCS1107A3UQDR at full ±50 A range from a single 3.3 V supply?

Three-phase inverters rated up to 15 kW, brushless DC motor drives with 48 V bus, and single-phase solar microinverters can all use the TMCS1107A3UQDR. The device draws only 10 mA supply current at 3.3 V, outputs a ratiometric analog voltage centered at VCC/2, and delivers 18.75 mV/A sensitivity across the full ±50 A measurement range, making it directly ADC-compatible without an external amplifier stage.

How does TMCS1107A3UQDR compare with a shunt resistor approach for current sensing on a 400 V rail?

Unlike a shunt resistor, the TMCS1107A3UQDR provides 420 V galvanic isolation, eliminating the need for a separate isolation amplifier. A 1 mΩ shunt on a 50 A rail dissipates 2.5 W continuously; the Hall-effect sensor dissipates effectively zero power in the primary path. Accuracy is ±1% full-scale over the -40°C to 85°C industrial temperature range, comparable to a precision shunt plus amplifier solution.
