After the AM6442 chip on the self-designed PCB enters DFU boot mode, when using USB 2.0 to program SBL and APP, the host shows: "Unknown USB device (Device descriptor request…
Hello,
Please refer to datasheet or EVM user guide to see difference using En or shunt dimming mode. Both EN and shunt dimming disable switching and LED current drop to 0 when EN/PWM is 0.
Shunt dimming is mature solution that used widely in LED driver…
Hi Lydia:
There is already internal 1kOhm resistor for discharge, and our EVM design just has a 0 ohm resistor here between VEE_DIS and VEE.
For example, in my circuit, VEE_DIS is a 750K resistor. Is this a VGL Fail issue?
If so, what is the cause?
