Product details

PCMCIA slot power switch with status flag

The Texas Instruments TPS2228PWP is a four-output high-side PCMCIA power switch designed to sequence VCC and VPP rails in CardBus and PCMCIA slots. It integrates a serial interface for control and a status flag output that asserts during over-current or over-temperature fault conditions.

97 mOhm on-resistance and 1 A per channel

Each of the four outputs is rated for 1 A continuous with a typical on-resistance of 97 mOhm.

The 3:4 input-to-output ratio implies an internal charge pump generates the gate drive for the fourth output from the available load rail.

It is no longer in production from Texas Instruments. Sourcing is limited to independent distribution and surplus inventory.

Frequently asked questions

Where can I buy the TPS2228PWP and get a price?
