General Description

Beneﬁts and Features

● Flexible System Design to Operate with Any USB

Charger Source

The MAX14746/MAX14747 are a series of USB charger

detectors with an integrated Smart Power Selector™ linear

charger solutions that provide a single-chip solution for

charging and charger detection.

• Compliant to USB Battery Charger Rev 1.2

Speciﬁcation*

• Supports Proprietary USB Charging Sources,

Including Apple

The MAX14746/MAX14747 charger detectors are compliant

to USB Battery Charger Detection Rev 1.2* and capable

of detecting multiple USB battery-charging methods,

including Standard Downstream Ports (SDP), Charging

Downstream Ports (CDP), and Dedicated Charger Ports

(DCP). The devices also detect common proprietary

charge adapters, including those from Apple.

• D+/D- Bias Voltage Supported

● Easy to Implement Li+ Battery Charging

• Smart Power Selector

• Fully Compliant with Dead Battery/Weak Battery

Charging According to USB 2.0 Speciﬁcation

• JEITA Charge Protection

• Thermal Protection

• Internal USB D+/D- Switch to Manage Connection

The MAX14746/MAX14747 battery chargers feature

Smart Power Selector operation, allowing operation with

dead or no battery present. The devices limit USB V

current based on the detect charger source type. If the

charger power source is unable to supply the entire system

load, the smart-power control circuit supplements the

system load with current from the battery.

BUS

● Integrates High Level of Protection

• 28V Tolerant Input on VB

• ±15kV Human Body Model ESD Protection on

CDP and CDN

The devices protect against overvoltage faults up to 28V.

This series of USB charger detectors are available with

several options, with slight variations in, for example,

power-up states. These variations are noted throughout

this data sheet.

Ordering Information appears at end of data sheet.

There are five options available, with slight variations in,

for example, power-up states (see Ordering Information).

The devices are available in a 25-ball, 0.4mm pitch wafer-

level package (WLP), and are specified over the -40°C to

+85°C extended temperature range.

Applications

● Portable Consumer Devices

● Portable Digital Cameras

● Portable Digital Video Cameras

● Portable Industrial Devices
