General Description

The TPS2216 PC Card power-interface switch provides an integrated power-management solution for two PC Cards.

All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on a single integrated circuit.

This device allows the distribution of 3.3-V, 5-V, and/ or 12-V power to the card.

Key Features

  • a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5-V power. This feature facilitates low-power system designs such as sleep modes where only 3.3 V is available. This device also has the ability to program the xVPP outputs independent of the xVCC outputs. A standby mode that changes all output-current limits to 50 mA (typical) has been incorporated. 5V 5V DATA CLOCK LATCH RESET 12V AVPP AVCC AVCC AVCC GND NC RESET 3.3V DB.
