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. 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 12-bump,
0.4mm pitch, 1.3mm x 1.68mm WLP and 16-pin TQFN
packages and operate over the -40NC to +85NC extended
temperature range.
