用BQ25703A设计1CELL 锂电池充电方案，目前使用TypeC接普通充电器（5V）可以充电，但是接带PD的适配器就无法充电，log显示pd disable，量测CHRG_OK在插入PD适配器后拉高，但很快就拉低了，请教下要使用PD快充，需要从哪方面来看，谢谢！2514.BQ25703A TypeC charge design.pdf

您好
Let's start by debugging why CHRG_OK is pulled low shortly after the USB PD adapter is plugged in. CHRG_OK should stay high as long as the VBUS voltage is valid (VVBUS_CONVEN < VBUS < VACOV) and there are no faults.
Can you please capture a waveform showing VBUS, CHRG_OK, REGN, and VSYS on the same graph, similar to Figure 48 in the datasheet?
