PRODUCTION DATA
The VINDPM feature is used to detect an input source voltage that is reaching its current limit due to excessive load and causing the voltage to reduce. When the input voltage drops to the VINDPM threshold (VIN_DPM), the internal pass FET reduces the current until there is no further drop in voltage at the input. This prevents a source with voltage less than the VIN_DPM to power the OUT pin. This unique feature makes the IC work well with current limited (for example, high impedance) power sources, such as solar panels or inductive charging pads. This is also an added safety feature that helps protect the source from excessive loads.
