DESCRIPTION
The TPS2231 and TPS2236 ExpressCard power interface switches provide the total power management solution
required by the ExpressCard specification. 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.

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.

(1) The package is available taped and reeled. 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.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
