New from Maxim Integrated Products are the MAX4987AE and MAX4987BE overvoltage-protection (OVP) controllers with internal overcurrent protection.
These devices integrate low-capacitance (3pF, typical) diodes to provide robust, +/-15kV ESD protection (Human Body Model) for High-Speed USB and USB (full-speed or low-speed) D+/D- signals.
The MAX4987AE and MAX4987BE are ideal for space-constrained applications, such as cellphones, smartphones, PDAs, MP3 players and portable video players that are attached to USB ports for connectivity or charging.
To reduce external component count and save space, the MAX4987AE and MAX4987BE integrate a low-on-resistance N-channel FET that protects low-voltage systems from overvoltages up to 28V.
