USB Charger Detectors

General Description

Beneﬁts and Features

● High Level of Integration

The MAX14576/MAX14636/MAX14637 are USB charger

detectors. The MAX14576/MAX14636/MAX14637 will

pass USB Battery Charger Specification Revision 1.2 (USB

BC 1.2) compliance tests. The MAX14636/MAX14637 can

also detect Apple chargers, and other nonstandard types.

These devices are capable of detecting multiple USB

battery charging methods, including standard downstream

ports (SDP), charging downstream ports (CDP), and dedi-

cated charger ports (DCP). The devices also feature USB

BC 1.2 defined dead-battery option support.

• Capability to Withstand -6V to +30V (Absolute

Maximum) on VBUS Line

• USB Battery Charger Detection

- Will Pass USB Battery Charger Speciﬁcation

Rev 1.2 Compliance Tests

- USB DCP, SDP, and CDP Detection

- Proprietary Charger Detection Capability

(MAX14636/MAX14637)

• USB 2.0 Hi-Speed Switch with 3Ω (typ) On-Resistance

and 4.5pF (typ) On-Capacitance

• High ESD Protection on CDP and CDN

- ±15kV—HBM

- ±15kV—IEC 61000-4-2 Air-Gap Discharge

- ±8kV—IEC 61000-4-2 Contact Discharge

• ±15kV HBM ESD Protection VBUS When Bypassed

with 0.1µF or Greater Ceramic Capacitor

The MAX14576/MAX14636/MAX14637 feature analog

switches that are capable of passing USB Hi-Speed, full-

speed, and low-speed signals. The switches have low on-

resistance (3I, typ) and low on-capacitance (4.5pF, typ).

The CDN and CDP are high ESD protected up to Q15kV

Human Body Model (HBM), Q15kV IEC61000-4-2 Air Gap

Discharge, and Q 8kV IEC61000-4-2 Contact Discharge.

● Save Power in Portable Applications

The MAX14576/MAX14636/MAX14637 are available in

a 10-pin (1.6mm x 2.1mm) UTQFN package and operate

over the 0°C to +70°C extended temperature range.

• Low Supply Current (150µA, typ)

● Space Saving

• 10-Pin, 1.6mm x 2.1mm, UTQFN Package
