EVALUATION KIT AVAILABLE
MAX14578E/MAX14578AE
USB Battery Charger Detectors
General Description
Features
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
monitor controlled by I²C communication (MAX14578E
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.
