Tool/software:
Hi,
We use the BQ25723 and there is an issue of output oscillation and excessive power supply current loss, resulting in abnormal overcurrent and power failure of the entire machine;
The spec. is input voltage 14VDC, the output voltage is 9.3VDC to 12.6VDC;
The waveform please refer to below:
1. When the system is turned on and in the SHELL interface, the output waveform is displayed. The image on the right shows the AC coupling after unfolding：
2. System startup in SHELL interface state, CH1: inductor phase, CH2: Vout:
3. Shutdown state applies dynamic load to Vout, with current ranging from 0A to 6A, slope of 2.5A/us, and frequency of 1000Hz. CH1: inductor phase, CH2: Vout:
4. Shutdown state applies dynamic load to Vout, with current ranging from 6A to 12A, slope of 2.5A/us, and frequency of 1000Hz. CH1: inductor phase, CH2: Vout:
5. The schematic diagram for your evaluate"
