MAX14578EWC+T

General 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 (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 charging 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.
