This user's guide describes the characteristics, operation, and use of the TMCS1100 evaluation module
(EVM). This EVM is designed to evaluate the performance of the
bidirectional 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 TMCS1100EVM. This
document includes a schematic, reference printed-circuit board (PCB) layouts, and a complete bill of
materials (BOM).

200 mV/A, and 400 mV/A. These devices operate from a single 3-V to 5.5-V power supply, drawing a maximum of 5 mA of supply current per amplifier channel. The TMCS1100 is currently available in an 8- pin, SOIC, surface-mount package. -
Page 5: Hardware
The TMCS1100 is an isolated, current-sense op amp that provides ease-of-use and high performance. The TMCS1100EVM is intended to provide basic functional evaluation of all TMCS1100 gain variants. The TMCS1100EVM is not laid out for electromagnetic compatibility (EMC) testing. The TMCS1100EVM consists of one PCB that can be snapped apart into four individual segments;... -

TP3x serves as a test-point for the filtered input to the TMCS1100 VREF pin while TP7x serves as a test point for the prefiltered input to the TMCS1100 VREF pin. J1x is a jumper that conveniently allows the TMCS1100 reference to be shorted to ground, connected directly to an external power supply, or shorted to a voltage set by a buffered voltage divider. - Page 7 Reference Divider Buffer U3x is the TLV376IDBVR. U3X is configured as a buffer that sets the TMCS1100 at mid-supply according to the voltage divider composed of R3x and R4x by default. The user has the option to either short out this buffer with a 0-Ω...
