BQ76952: BQ76952芯片反接问题

Section 2 Reverse Charge Circuit from the Multiple FETs with the BQ769x2 Battery Monitors application note should help explain and show a reverse charge circuit we typically recommend.

我现在的问题是 充电器反接后，PDSG管脚的电压比电池电压低，会导致预放mos处于半开不开的状态。

Do you also have the Schottky diodes D6 and D8 as shown in Figure 1-1. Typical 7S Series FET Schematic from the Multiple FETs application note? Section 3 Reverse Charge Component Selection from the application note, also discusses the reverse charge current paths and explains how those diodes help.
