The TPS2231 and TPS2236 ExpressCard power interface switches distribute 3.3 V, AUX, and 1.5 V to the ExpressCard socket. Each voltage rail is protected with integrated current-limiting circuitry. The TPS2231 supports systems with single-slot ExpressCard|34 or ExpressCard|54 sockets. The TPS2236 supports systems with dual-slot ExpressCard sockets. End equipment for the TPS2231 and TPS2236 include notebook computers, desktop computers, personal digital assistants (PDAs), and digital cameras.

Copyright © 2004–2009, Texas Instruments Incorporated TPS2231 TPS2236 SLVS536J – JULY 2004 – REVISED SEPTEMBER 2009.................................................................................................................................................. www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Add an R suffix to device types (e.g., TPS2231PWPR). (2) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. (3) The TPS2231MRGP is identical to the TPS2231 with the exception of the PowerPAD dimensions. See the Thermal Pad Mechanical data portion of this data sheet for specific information. The thermal pad for the TPS2231MRGP and TPS2231MRGP-1 is 2,2 mm × 2,2 mm; the thermal pad for the TPS2231RGP is 2,7 mm × 2,7 mm. (4) The TPS2231MRGP-1 is identical to the TPS2231MGRP with the exception that the orientation of the part in the reel is rotated 180°. See the Package Materials Information portion of this data sheet for specific information. (5) The TPS2231MRGP-2 is identical to the TPS2231MRGP with the exception that the orientation of the part in the reel is rotated 90° and does not have an internal pull-up resistor between AUX IN and SYSRST. See the Package Materials Information portion of this data sheet for specific information. (6) The TPS2231MRGP-3 is identical to the TPS2231MRGP with the exception that the 1.5VIN and 3.3VIN UVLO circuits are independent.
