1.
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 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 WL...
