MAX14656

USB Charger Detection

with Integrated Overvoltage Protector

General Description

Beneﬁts and Features

● Consumes Less Power

The MAX14656 is a USB charger detector compliant with

USB Battery Charging Specification Revision 1.2. 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.

• Low Battery Standby Current 5µA (typ)

● Delivers USB Compliance and Flexibility

• Compliant to USB Battery Charging Speciﬁcation

Revision 1.2

• Data Contact Detection for Foolproof Connector

Insertion Detection

The device implements USB Battery Charging

Specification Revision 1.2-compliant detection logic. The

• Dedicated Charger Detection

• Standard Downstream Port Detection

• Charging Downstream Port Detection

• Apple Charger Detection

device also includes Apple charger detection that allows

identification of resistor divider networks on D+/D-.

The internal double-pole double-throw (DPDT) USB

switch is compliant to Hi-Speed USB, full-speed USB,

low-speed USB, and UART signals. The device’s internal

switch features low on-resistance, low on-resistance flat-

ness, and very low capacitance. The ID pin controls the

DPDT switch position. The MAX14656 features high-ESD

protection up to ±15kV Human Body Model (HBM)on

CD+, CD-, and ID pins.

• Sony Charger Detection*

● Facilitates System Design

• Integrated Precision 1.5A Overvoltage

Protection (OVP)

• Negative Audio Capable DPDT Hi-Speed USB

Switches

• Automatic Switch and Charger Interface Control

• Full Control by I C Interface

The MAX14656 is available in a 16-bump, 0.4mm pitch,

1.8mm x 1.9mm WLP package and operates over the

-40ºC to +85ºC extended temperature range.

• Interrupt for Device Status Change

● Saves Board Space

• V

Connection Capable of 36V

BUS

Applications

● DSCs and Camcorders

• ±15kV HBM ESD Protection

• 1.8mm x 1.9mm WLP Package

● Tablet PCs

● Smartphones

● e-Readers
