SLVSE19B June 2019 – November 2021 TPS1HB50-Q1
PRODUCTION DATA
Inverse current occurs when 0 V < VBB < VOUT. In this case, current can 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 can be greater than VBB.
The TPS1HB50-Q1 will not detect inverse current. When the switch is enabled, inverse current will pass through the switch. When the switch is disabled, inverse current can pass through the MOSFET body diode. The device will continue operating in the normal manner during an inverse current event.
