Product details

PCMCIA slot power switch — four channels, three voltage rails

The Texas Instruments TPS2206ADAPRG4 is a PCMCIA power-distribution switch designed to manage the VCC and VPP supplies in PC Card slots. It integrates four high-side outputs with a 3:4 input-to-output ratio, routing 3.3V, 5V, or 12V to the card as the host interface selects.

95 mOhm Rds(on) and the thermal budget

At 1 A per output, the 95 mOhm typical Rds(on) produces 95 mW of I²R loss per channel.

Fault protection and status flag

Built-in current limiting (fixed threshold) and over-temperature shutdown protect the switch and the card slot from short circuits or excessive draw. A status flag output signals fault conditions to the host controller over the serial interface.

Frequently asked questions

Does TPS2206ADAPRG4 support 12V load?

Yes, it supports 3.3V, 5V, and 12V loads — the three voltage rails that PCMCIA and CardBus slots require for VCC and VPP programming.

What is the Rds(on) of TPS2206ADAPRG4?

The typical on-resistance is 95 mOhm per channel, specified at the rated output current.

What package is TPS2206ADAPRG4?

It comes in a 32-TSSOP package with an exposed thermal pad, 0.240-inch body width (6.10 mm), designated as 32-HTSSOP in the supplier device package field.
