The TMCS1100-Q1 is a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability. A low-drift, temperature-compensated signal chain provides < 1% full-scale error across the device temperature range.

The input current flows through an internal 1.8mΩ conductor that generates a magnetic field measured by an integrated Hall-effect sensor. This structure eliminates external concentrators and simplifies design. Low conductor resistance minimizes power loss and thermal dissipation. Inherent galvanic insulation provides a 600V lifetime working voltage and 3kVRMS basic isolation between the current path and circuitry. Integrated electrical shielding enables excellent common-mode rejection and transient immunity.

The output voltage is proportional to the input current with four sensitivity options. Fixed sensitivity allows the TMCS1100-Q1 to operate from a single 3V to 5.5V power supply, eliminates ratiometry errors, and improves supply noise rejection. The current polarity is considered positive when flowing into the positive input pin. The VREF input pin provides a variable zero-current output voltage, enabling bidirectional or unidirectional current sensing.

The TMCS1100-Q1 draws a maximum supply current of 6mA, and all sensitivity options are specified over the operating temperature range of –40°C to +125°C.

TMCS1100EVM — TMCS1100 절연 홀 효과 전류 감지 평가 모듈

TMCS1100EVM은 외부 레퍼런스를 사용하는 절연 홀 효과 정밀 전류 감지 모니터인 TMCS1100을 빠르고 간편하게 사용할 수 있도록 설계된 도구입니다. 사용자는 이 평가 모듈(EVM)을 사용해 최대 작동 전류를 홀 입력측을 통해 푸시하면서 동시에 절연 출력을 측정할 수 있습니다. 고정 레이아웃은 대상 회로의 모델로 의도된 것이 아니며, EMI(전자기장) 테스트용으로 배치된 것도 아닙니다. TMCS1100EVM 은 다양한 디바이스 변형을 평가할 수 있도록 4개의 개별 조각으로 분리 가능한 단일 PCB로 구성되어 있습니다.
