TPS2231

TPS2236

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.

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.

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.
