Nonstandard Chargers—Wasteful and Inconvenient
*Future product—contact factory for availability.
Charger Detector Enables Universal USB Charging
As consumers buy more portable devices, they become overwhelmed with managing the various power
adapters that have nonstandard connectors . Solving this issue, the micro USB connector has been universally
accepted for battery charging and data transfer . Though USB requirements are complex, the MAX14578’s
charger detection, overvoltage protection, and current-limit switching ease the implementation of micro USB
connectors to simplify the user experience .
• Mobile device vendors ship proprietary AC
• Accumulation of incompatible charger adapters
charger adapter with their products
is wasteful and inconvenient for the user
