MAX14578E/MAX14578AE USB Battery Charger Detectors


Maxim's MAX14578E/MAX14578AE USB charger detectors are compliant with USB Battery Charging Revision 1.1


Maxim - MAX14578Maxim's MAX14578E and 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 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 (active-low EN) input and an LDO output.

In addition, the internal USB switch is compliant to high-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 ±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 and MAX14578AE are available in both a 12-bump, 0.4 mm pitch, 1.3 mm x 1.68 mm WLP package and 16-pin TQFN package, and operate over the -40°C to +85°C extended temperature range.
