Description
The  MAX14578E/MAX14578AE are  USB charger detectors  compliant  with USB  Battery Charging  Revision 1.1.
The  USB  charger detection  circuitry  detects USB standard downstream ports  (SDP), USB charging
downstream ports (CDP),  or  dedicated charger ports (DCP), and  controls  an  external lithium-ion (Li+) battery
charger.
The  MAX14578E/MAX14578AE 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  charging support. Dead battery charging  support  features a 45 minutes  (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
MAX14578E/MAX14578AE  feature high -ESD  protection up to ±15kV  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 a 12-bump, 0.4mm pitch, 1.3mm  x  1.68mm  WLP package
and operate over  the - 40°C to +85°C extended temperature range
