LM66200 Evaluation Module 1

1 Introduction

The LM66200EVM is an evaluation module for the LM66200 low IQ ideal diode. The LM66200 is a dual-input,

single-output device that automatically passes the higher of its two input voltage to the output. The low quiescent

current makes the LM66200 ideal for systems with a battery supply as an input to extend the life of the battery

when in use.

1.1 Description

The LM66200EVM is a two layer PCB that enables the evaluation of the LM66200 low IQ ideal diode. This EVM

contains multiple jumpers to configure the different modes of operation of the LM66200. Table 1 lists the different

modes of operation.

For additional details on ideal diodes, and the data sheet, see Ideal diode & OR-ing Controllers on TI.com.

STANDARD TERMS FOR EVALUATION MODULES

1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or

documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance

with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.

1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility

evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not

finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For

clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions

set forth herein but rather shall be subject to the applicable terms that accompany such Software

system.

2Limited Warranty and Related Remedies/Disclaimers:

2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License

Agreement.

2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM

to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by

neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have

been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications

or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control

techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.

User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)

business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.

2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit

User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty

period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or

replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be

warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day

warranty period.

WARNING

Evaluation Kits are intended solely for use by technically qualified,

professional electronics experts who are familiar with the dangers

and application risks associated with handling electrical mechanical

components, systems, and subsystems.

User shall operate the Evaluation Kit within TI’s recommended

guidelines and any applicable legal or environmental requirements

as well as reasonable and customary safeguards. Failure to set up

and/or operate the Evaluation Kit within TI’s recommended

guidelines may result in personal injury or death or property

damage. Proper set up entails following TI’s instructions for

electrical ratings of interface circuits such as input, output and

electrical loads.

NOTE:

EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION

KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.
