What are the key features of TMCS1107A3BQDRQ1?
- ±420 V reinforced galvanic isolation between the current path and signal output, protecting low-voltage MCU analog inputs in high-voltage automotive and industrial systems
- AEC-Q100 qualified for -40°C to +125°C operation, meeting automotive reliability standards for under-hood and powertrain current sensing applications
- Analog voltage output with integrated internal reference eliminating the need for an external reference supply and simplifying ADC input circuit design
- Hall-effect sensing with no resistance in the current path, avoiding insertion loss and eliminating the risk of thermal runaway from shunt resistor heating
- Compact 8-pin SOIC surface-mount package (4.9 mm x 3.9 mm x 1.5 mm) enabling high-density PCB placement near measurement points in motor control inverters
What is TMCS1107A3BQDRQ1 used for?
TMCS1107A3BQDRQ1 is used in automotive traction inverters and on-board chargers where phase current must be measured while maintaining ±420 V of galvanic isolation from the high-voltage battery bus to protect the low-voltage control electronics. It suits industrial motor drives, solar inverters, and energy storage systems that require isolated AC current measurement with an analog output directly readable by a microcontroller's ADC. The AEC-Q100 qualification also makes it appropriate for electric vehicle DC-DC converters and hybrid powertrain current monitoring where both high isolation voltage and wide-temperature-range reliability are mandatory.

Frequently Asked Questions
How much galvanic isolation does TMCS1107A3BQDRQ1 provide, and why is this critical in an EV battery charger design?
TMCS1107A3BQDRQ1 provides ±420 V reinforced galvanic isolation between the current-carrying conductor and the signal output pins. In an electric vehicle on-board charger operating from a 400 V battery bus, this isolation protects the 3.3 V MCU analog input from lethal voltages during normal operation and fault conditions, eliminating the need for an external optocoupler or transformer-based isolation stage that would add cost, latency, and board area.
What temperature range does TMCS1107A3BQDRQ1 support, and which automotive qualification does it meet?
TMCS1107A3BQDRQ1 operates from -40°C to +125°C and is qualified to AEC-Q100, the automotive IC reliability standard. The -40°C lower limit covers cold-start conditions in Arctic climates, while +125°C covers sustained under-hood ambient temperatures near engine compartments. This AEC-Q100 qualification makes it directly applicable to body control modules, inverter gate driver feedback circuits, and ADAS power supply current monitoring without additional qualification testing.
Does TMCS1107A3BQDRQ1 require an external voltage reference, and how does this affect PCB design?
TMCS1107A3BQDRQ1 includes an integrated internal voltage reference, so no external precision reference IC is needed for the analog output to be ratiometric or absolute. Eliminating an external reference reduces BOM count by 1–2 components (reference IC plus decoupling capacitors), saves approximately 4 mm² of PCB area, and removes a potential noise injection path that can degrade current measurement accuracy in high-dv/dt switching environments.
For a solar string inverter, how does Hall-effect sensing in TMCS1107A3BQDRQ1 compare to a shunt resistor approach?
TMCS1107A3BQDRQ1 uses Hall-effect sensing with no resistive element in the current path, resulting in zero insertion loss and no self-heating at high currents, unlike a 1 mΩ shunt resistor that dissipates 1 W at 31.6 A and requires a separate differential amplifier stage. For a 10 kW solar string inverter running 25 A DC input current, the Hall-effect approach improves system efficiency by 0.01–0.02% and eliminates thermal derating concerns on the measurement element.
