With some prototype units utilizing the BQ77901A Battery Control IC, when turning on the discharge fet the battery monitor ic quickly disables the fet drive, then 100mSeconds later the monitor turns the fet drive on, which is again quickly disabled, and the process repeats with the battery being turned on and off at a 10 hz rate. This issue appears to go away after a couple of minutes, we have not been able to recreate it. It is not clear to me that I can count on this behavior not reappearing. The turn off is correlated in time with a current inrush pulse of about 15A, the pulse width is about 200useconds, which is far below the Short circuit time delay setting of 960uSecs. Our circuit does utilize a pull down resistor of 100K on the ZEDE line, which may be too high in value, causing the time delays to be ignored. There does seem to be a correlation of the 100msecond oscillation period and the published Power-up sequence of 100mseconds.
