The ISOTMP35-Q1 is the industry’s first isolated temperature sensor IC, combining an integrated isolation barrier, up to 3000VRMS withstand voltage, with an analog temperature sensor featuring a 10mV/°C slope from –40°C to 150°C. This integration enables the sensor to be co-located with high voltage heat sources (for example: HV FETs, IGBTs, or HV contactors) without requiring expensive isolation circuitry. The direct contact with the high-voltage heat source also provides greater accuracy and faster thermal response compared with approaches where the sensor is placed further away to meet isolation requirements.

Operating from a non-isolated 2.3V to 5.5V supply, the ISOTMP35-Q1 allows easy integration into applications where sub-regulated power is not available on the high-voltage plane.

The integrated isolation barrier satisfies UL 1577 requirements. The surface mount package (7-pin SOIC) provides excellent heat flow from the heat source to the embedded thermal sensor, minimizing thermal mass and providing more accurate heat-source measurement. This reduces the need for time-consuming thermal modeling and improves system design margin by reducing mechanical variations due to manufacturing and assembly.

The ISOTMP35-Q1 class-AB output driver provides a strong 500µA maximum output to drive capacitive loads up to 1000pF and is designed to directly interface with analog-to-digital converter (ADC) sample and hold inputs.

ISOTMP35BEVM — ISOTMP35 평가 모듈

설계자는 ISOTMP35BEVM EVM(평가 모듈)에서 USB 인터페이스와 제어 및 데이터 로깅 기능을 하는 온보드 MSP430F5528 MCU(마이크로컨트롤러)를 이용해 ISOTMP35 아날로그 절연 온도 센서의 성능을 평가합니다. 센서를 메인보드에서 분리할 수 있어 ISOTMP35의 원격 작동이 가능합니다. 또한 EVM에는 고전압 열원에 연결할 수 있는 뒷면 구리판이 있어 온도 정확도와 전압 절연을 모두 평가할 수 있습니다.
