Part #	Name	Product Family	Comments
TPS2041B	Single-Channel Current-Limited Power Distribution Switch	PCMCIA AND USB - USB POWER SWITCHES	TPS2041used for ganged-port power management provides overcurrent protection for the downstream ports. See Literature slls413e
TPS2044B	Quad Current-Limited Power Distribution Switches	PCMCIA AND USB - USB POWER SWITCHES	The overcurrent protection can be provided by a TPS2044 quad device or a TPS2024 single power switch. It is recommended to use TPS2041B instead of TPS2024 and TPS2044B instead of TPS2044. See Literature slls413e Recommend keeping the outputs individually connected to all ports instead of ganged together
