Applications
TMCS1101A1UQDRQ1 is designed for automotive battery management systems, motor drive current monitoring, and traction inverter feedback loops where galvanic isolation is required. Its reinforced 3000 V RMS isolation and AEC-Q100 Grade 1 rating make it suitable for EV/HEV powertrain modules measuring currents up to ±50 A. The analog output integrates directly with microcontroller ADC inputs in 48 V mild-hybrid and high-voltage BMS architectures.

Frequently Asked Questions
What isolation voltage does TMCS1101A1UQDRQ1 support, and how does it protect automotive circuits?
TMCS1101A1UQDRQ1 provides 3000 V RMS reinforced isolation, protecting low-voltage MCU circuits from high-voltage bus transients up to ±50 A in automotive powertrain and battery management applications operating from -40°C to 125°C.
Which supply voltage range is compatible with TMCS1101A1UQDRQ1 for a 3.3 V MCU design?
TMCS1101A1UQDRQ1 operates from a 3.3 V to 5 V supply, making it directly compatible with 3.3 V microcontrollers. The 50 mV/A analog output scales to the ADC reference with no additional signal conditioning needed for currents up to ±50 A.
How does TMCS1101A1UQDRQ1 compare to a shunt-based solution for traction inverter current sensing?
Unlike shunt resistors, TMCS1101A1UQDRQ1 provides full galvanic isolation with 3000 V RMS reinforced insulation, eliminating the need for separate isolation amplifiers. It achieves ±1% full-scale accuracy across its ±50 A range and 8-pin SOIC-8 footprint reduces board area versus discrete isolated designs.
What package does TMCS1101A1UQDRQ1 use and what are its PCB mounting dimensions?
TMCS1101A1UQDRQ1 comes in an 8-pin SOIC-8 small outline surface mount package measuring 4.9 mm × 3.9 mm × 1.5 mm body, suitable for standard PCB reflow assembly with a Pb-free, RoHS-compliant finish.
