Applications
The TMCS1108A1BQDRQ1 is designed for automotive inverters, on-board chargers, and EV battery management systems requiring isolated current measurement on high-voltage rails. Its ±100 V isolation and AEC-Q100 Grade 1 certification make it suitable for 48 V and 400 V traction systems where safety isolation between the power bus and MCU is mandatory. Industrial motor drives and solar inverters also benefit from its analog voltage output, which interfaces directly with standard ADC inputs without additional signal conditioning.

Frequently Asked Questions
What isolation voltage does the TMCS1108A1BQDRQ1 provide and is it sufficient for 48 V automotive battery systems?
The TMCS1108A1BQDRQ1 provides ±100 V galvanic isolation between the current-carrying conductors and the analog output signal path. For 48 V mild-hybrid automotive systems, this exceeds the minimum isolation requirement with a comfortable margin, and the AEC-Q100 Grade 1 qualification confirms reliable operation from -40°C to +125°C in under-hood environments.
How does the internal reference in TMCS1108A1BQDRQ1 simplify system design compared to external-reference current sensors?
The TMCS1108A1BQDRQ1 includes an integrated internal reference that sets the output midpoint at VCC/2 for a ratiometric output, eliminating the need for a precision external reference voltage source. This reduces the BOM by at least 2 passive components and simplifies PCB layout, particularly in automotive ECUs where board space near the current measurement node is limited to a few square millimeters.
For which automotive power conversion applications is TMCS1108A1BQDRQ1 best suited given its temperature and isolation specs?
TMCS1108A1BQDRQ1 is best suited for automotive DC-DC converters, traction inverters, and onboard chargers operating at bus voltages up to ±100 V. Its -40°C to +125°C operating range covers worst-case under-hood thermal cycling, and the analog voltage output enables direct ADC sampling at MCU logic levels (typically 3.3 V or 5 V) without an additional isolation amplifier stage.
What body dimensions does the 8-SOIC package of TMCS1108A1BQDRQ1 have and how does it fit on a standard automotive PCB?
The TMCS1108A1BQDRQ1 8-SOIC package measures 4.905 mm × 3.895 mm × 1.5 mm body height, with a standard 1.27 mm lead pitch. This footprint fits within a 6 mm × 5 mm PCB keep-out zone, making it compatible with standard automotive-grade PCB manufacturing rules and allowing placement close to shunt resistors or current-carrying traces on 4-layer power boards.
