Each output includes a load discharge feature that pulls the output to ground when the switch is off, preventing floating rails on downstream loads. The two channels share a common bias supply but switch independently via separate On/Off inputs. The non-inverting input logic and 1:1 input-to-output ratio simplify integration into existing power-sequencing schemes.
Each of the two outputs is rated for 6 A continuous maximum. The 18 mOhm typical Rds(on) keeps conduction loss manageable at full load, but the actual current capability depends on PCB copper area and ambient temperature — the 125°C junction limit is the hard ceiling.
Yes, the TPS22966DPUR includes a load discharge feature on each output. When the switch is turned off, an internal pull-down resistor discharges the output capacitance to ground, preventing the output from floating at an unknown voltage.
The two variants share the same die and electrical specifications — both are dual 6 A load switches with 18 mOhm Rds(on) and load discharge. The difference is the package: the DPUR suffix is the 14-WSON (3x2 mm) package, while the DGS suffix is the 14-VSSOP (3x3 mm) package. The WSON offers a smaller footprint but requires a more careful rework profile due to the exposed pad and lack of visible leads.
