1 Introduction

This User’s Guide details the ISO154x Evaluation Module (EVM) operation of the factory-installed ISO1540 and ISO1541 I2C-compatible bidirectional isolators. The EVM may be reconfigured for use with two ISO1540 or two ISO1541 instead of one of each.

This Guide presents a typical laboratory setup used with this EVM.

CAUTION:

This Evaluation Module (EVM) is made available for isolator parameter performance evaluation only and is not intended for isolation voltage testing. To prevent damage to the EVM, any voltage applied as a supply or digital input/output must be maintained within the 0 V to 5.5 V recommended operating range.

Exceeding the specified input voltage range may cause unexpected operation and irreversible damage to the EVM. If there are questions concerning the input voltage range, contact a TI field representative prior to connecting power.

Applying loads outside the specified output range may result in unintended operation and possible permanent damage to the EVM. If there is uncertainty as to the load specification, contact a TI field representative.
