Hello, we have a L9907 evaluation kit and we are trying implement the software to get L9907 to run. We have some problems we need support for:we supply the board at 24V and are using the VBAT_Scal circuitry to scale down the voltage on the VB pin, but we get an undervoltage error; from the datasheet, it seams the VB undervoltage should be 4.6V. Is this information correct, or there is another undervoltage threshold?
