Ordering Information/Selector Guide

General Description

The MAX14578E/MAX14578AE are USB charger detec-

tors compliant with USB Battery Charging Revision 1.1.

The USB charger-detection circuitry detects USB stan-

dard downstream ports (SDPs), USB charging down-

stream ports (CDPs), or dedicated charger ports (DCPs),

and controls an external lithium-ion (Li+) battery charger.

The devices implement USB Battery Charging Revision

1.1-compliant detection logic including data contact

detection, D+/D- short detection, charging downstream

port identification, and optional USB dead-battery charg-

ing support. Dead-battery charging support features a

45-minute (max) charge timer and weak battery voltage

only.) The MAX14578AE features an enable (EN) input

and an LDO output.

In addition, the internal USB switch is compliant to

Hi-Speed USB, full-speed USB, and low-speed USB

signals. The devices feature low on-resistance, low

on-resistance flatness, and very low capacitance. The

devices also feature high-ESD protection up to Q15kV

Human Body Model on the CD+ and CD- pins.

In addition, the MAX14578E/MAX14578AE feature Apple

and Sony charger detection that allows identification of

resistor-divider networks on D+/D-.

The MAX14578E/MAX14578AE are available in both a

12-bump, 0.4mm pitch, 1.3mm x 1.68mm WLP package

and 16-pin TQFN package, and operate over the -40NC

to +85NC extended temperature range.
