The TMCS1108 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 <3% full-scale error across the device temperature range.

The input current flows through an internal 1.8-mΩ 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 100-V functional 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 multiple sensitivity options. Fixed sensitivity allows the TMCS1108 to operate from a single 3-V to 5.5-V power supply, eliminates ratiometry errors, and improves supply noise rejection. The current polarity is considered positive when flowing into the positive input pin. Both unidirectional and bidirectional sensing variants are available.

The TMCS1108 draws a maximum supply current of 6 mA, and all sensitivity options are specified over the operating temperature range of –40°C to +125°C.

TMCS1108EVM — TMCS1108 隔離式霍爾效應電流感測評估模組

TMCS1108EVM 旨在協助方便快速地使用 TMCS1108，這是一款採用內部比率參考的隔離式霍爾效應精密電流感測監控器。此評估模組 (EVM) 可讓設計人員在測量隔離輸出時，將最大操作電流推經霍爾輸入側。此固定裝置佈局不做為目標電路模型使用，也不是為了電磁 (EMI) 測試所進行的佈局。

TMCS1108EVM 包含單一印刷電路板 (PCB)，可分為八個獨立部分。其中有四個部分與 TMCS1108 的四種單向變體對應，剩下四個部分則對應至裝置的雙向變體。
