1 Protector Tuning

This section covers how to set the protection values using the protector tuning method.

The protector tuning method does not require any reference voltage to be placed on the device to trim the protections. The expected typical error for UVP and OVP protections is 50mV. The expected typical error for OCC,OCD, and SCD protections is 3mV.

Step 1: Download and install the latest version of BQSTUDIO-TEST.

Step 2: Connect EV2400 with BQ27Z746EVM as in Figure 1-1.
