PRODUCTION DATA
Inverse current occurs when 0 V < VBB < VOUT. In this case, current may flow from VOUT to VBB. Inverse current cannot be caused by a purely resistive load. However, a capacitive or inductive load can cause inverse current. For example, if there is a significant amount of load capacitance and the VBB node has a transient droop, VOUT may be greater than VBB.
TPS27SA08 device will not detect inverse current. When the switch is enabled, inverse current will pass through the switch. When the switch is disabled, inverse current may pass through the MOSFET body diode. The device will continue operating in the normal manner during an inverse current event.
