The MAX14578E/MAX14578AE are USB charger detectors compliant with USB Battery Charging Revision 1.1. They detect USB standard downstream ports (SDPs), USB charging downstream ports (CDPs), or dedicated charger ports (DCPs), and control an external lithium-ion (Li+) battery charger. The devices implement USB Battery Charging Revision 1.1-compliant detection logic including data contact detection, D+/D- short detection, charging downstream port identification, and optional USB dead-battery charging support. The MAX14578AE features an enable (EN) input and an LDO output. In addition, the internal USB switch is compliant to Hi-Speed USB, full-speed USB, and low-speed USB signals. The devices feature low on-resistance, low on-resistance flatness, and very low capacitance. The devices also feature high-ESD protection up to Q15kV Human Body Model on the CD+ and CD- pins. In addition, the MAX14578E/MAX14578AE feature Apple and Sony charge.
The MAX14578E and MAX14578AE are USB charger detectors that identify Standard Downstream Ports (SDP), Charging Downstream Ports (CDP), and Dedicated Charger Ports (DCP). They support Apple and Sony charger detection, feature low on‑resistance, high‑ESD protection, and the MAX14578AE adds an enable input and an LDO output.
The devices are offered in a 12‑bump WLP package and a 16‑pin TQFN package, operating over a temperature range of –40 °C to +85 °C. The datasheet provides absolute maximum ratings, electrical characteristics, pin/bump configurations, package outlines, and revision history for design reference.
