The USB charger-detection circuitry detects USB standard downstream ports (SDPs), USB charging downstream 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. In addition, the internal USB switc...
