Important Note

This EVM requires the use of a communications tranciever, the EV2400. If one is not already available to you then one can be ordered throught the eStore.


The BQ27545EVM along with bqEVSW provides the customer tools for developing battery fuel gauging modules for a pack-side fuel gauge solution. Customers are able to configure BQ27545EVM so that it can provide accurate battery fuel gauging information. BQ27545EVM gives the customer information such as battery voltage, temperature measurement, Remaining State of Charge and Run Time to Empty through its RAM registers. The BQ27545EVM allows the customer to evaluate the BQ27545 IC according to its datasheet.
