TDA4VE-Q1: TDA4VE 烧录咨询

Part Number: TDA4VE-Q1

此器件支持efuse功能且有两个Efuse供电端口VPP_MCU和VPP_CORE.

应用场景:产品需要在产线下线前进行功能烧录,且须支持数据回滚和客户现场FOTA。

1.实现这些应用场景可以板内独立的LDO给TDA4 Efuse供电还是外部通过TP在产线烧录即可。

2.如果在产品内使用LDO给Efuse供电,那么VPP_MCU和VPP_CORE都必须供电吗?在数据手册中需要给两者供电,但是在EVM变更中,只需要给VPP_MCU供电。

此问题十分紧急,望能快速支持。此前我已经在E2E上提单,但是未有回复,详情请参考。https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1591260/tps7a21-q1-how-to-supply-for-tda4ve-vpp/6133372
