ABRIDGED DATA SHEET
EVALUATION KIT AVAILABLE
USB Charger Detection
with Integrated Overvoltage Protector
General Description
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.
The device implements USB Battery Charging
Specification Revision 1.2-compliant detection logic. The
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.
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.
