BQ24232: Reverse current on BQ24232

Part Number: BQ24232


Customer uses BQ24232 with below circuit:

U6 is a boot converter, U70 is BQ24232,  BAT_VCC connects to a small battery.

V_BAT connect to external battery to charger internal battery on BAT_VCC, the current is 30mA and meets design spec. 

when removing the battery on V_BAT, there is a reverse current from U70 to U6, the current is higher to 63mA. and also see an oscillation on PV50 point(input of U70)

Could you check and give some comments for this phenomena?

Dose BQ24232 has reverse current blocking feature?
