1.1 Introduction

This user’s guide describes the characteristics, operation, and use of the TMCS1133 evaluation module (EVM). This EVM is designed to evaluate the performance of the TMCS1133 voltage output isolated Hall-effect current sense amplifiers in a variety of configurations. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the TMCS1133xEVM. This document includes a schematic, reference printed-circuit board (PCB) layouts, and a complete bill of materials (BOM).

The TMCS1133 Hall-effect current sense amplifier (also called an isolated current-sense amplifier) senses magnetic flux generated from current passing through the lead frame at common-mode voltages from 0 VDC to ±1100 VDC, independent of the supply voltage. The device is available with zero-input reference point configurations of 2.5 V (A), 1.65 V (B), and 0.33 V (C), with fixed sensitivities available: 25 mV/A, 33 mV/A, 50 mV/A, 75 mV/A, 100 mV/A, and 150 mV/A. These devices operate from a single 3-V to 5.5-V power supply, drawing a maximum of 9.2 mA of supply current. The TMCS1133 is currently available in a 10-pin, SOIC, fused lead, surface-mount package. Table 2-1 lists the available sensitivity options.
