MAX14576：USB Charger Detectors

Compliant with USB Battery Charger Specification Revision 1.2 (USB BC 1.2)

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 dedicated charger ports (DCP). The devices also feature USB BC 1.2 defined dead-battery option support. 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 (3Ω, typ) and low on-capacitance (4.5pF, typ). The CDN and CDP are high ESD protected up to ±15kV Human Body Model (HBM), ±15kV IEC61000-4-2 Air Gap Discharge, and ±8kV IEC61000-4-2 Contact Discharge. The MAX14576/MAX14636/MAX14637 are available in a 10-pin (1.6mm x 2.1mm) UTQFN package and operate over the -40°C to +85°C extended temperature range.
