VBAT 2S EVM Hardware Configuration

This section shows how to set the EVM jumpers in order to evaluate TAS2574EVM in a 2 S battery application for VBAT as depicted in Figure 1-2.

In this case, VBAT pin C1 must still be connected to a power supply range from 3 V up to 5 V, while VBAT_SNS and the boost inductor can be connected to a higher 2 S supply range from 4.5V up to 9 V.

  • VBAT pin C1 connection can be connected to USB-5V by changing J56 position to 2-3 instead of 1-2.
  • VBAT_SNS pin C4 connection can be modified using J28, this connection is optional.
  • 2 S VBAT supply is directly available at J30 (or J72) and J31 (or J73) for channel-1 and J55 (or J58) and J3 (or J59) for channel-2. If using J43 to supply 2 S battery voltage, then make sure to change J45 to use +5V_MB instead.
