Maxim MAX14578E/MAX14578AE USB battery charger detectors
Maxim has announced the MAX14578E/MAX14578AE, claimed to be the smallest USB battery charger detectors that are compliant with the USB battery charging specification.
The devices detect USB standard downstream ports, USB charging downstream ports or dedicated charger ports, in addition to proprietary charger adapters from Apple and Sony.
When a charging port is detected, the detectors control an external lithium-ion (Li+) battery charger controller to optimise charge time and charging efficiency.
An on-chip LDO provides a 5.3 V output which can be used to power a USB transceiver. In addition, ESD protection on the USB data pins is extended up to ±15 kV (human body model) and ±8 kV IEC 61000-4-2 contact discharge.
