Small, High-Performance USB Switches Integrate Low
Power and High-ESD Protection
Multiplex Both USB and Analog Signals in Handheld Devices
2
The MAX14585*/MAX14585A* high-ESD-protected DPDT switches multiplex Hi-Speed USB (480Mbps) and
analog signals such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and
low on-resistance (RON) necessary for high-performance switching applications in portable electronics. They
include an internal negative supply to pass audio signals that swing down to -1.8V below ground.

Mobile device vendors ship proprietary AC
charger adapter with their products
Accumulation of incompatible charger adapters
is wasteful and inconvenient for the user
Provides USB power adapter detection
Allows USB charging from various adapters
Enables USB dead battery charging support
without complex software modification
As consumers buy more portable devices, they become overwhelmed with managing the various power
adapters that have nonstandard connectors. Solving this issue, the micro USB connector has been universally
accepted for battery charging and data transfer. Though USB requirements are complex, the MAX14578’s
charger detection, overvoltage protection, and current-limit switching ease the implementation of micro USB
connectors to simplify the user experience.

MAX13202E/04E/06E/08E
±30kV ESD-Protection Diode Arrays
Protect sensitive electronics attached to
communication lines
Each channel consists of a pair of diodes that steer
ESD current pulses away from protected circuitry
to VCC or GND
Ultra-low 1nA (max) leakage current eases limited
power budgets
Low 6pF input capacitance is ideal for high-speed
data lines

Integrated FET’s low 50mΩ RON
makes this part suitable for
handling higher power
Optimized design fits in small
2mm x 2mm, 8-pin TDFN package
for small solution footprint
Warning flag output provides
feedback to system
• Blanking timeout
• Reverse-current detection
• Thermal shutdown
• Device disable status
Adjustable current-limit
threshold gives more
flexibility for customization
of system protection
Wide 250mA to 2.5A
current-limit range allows
use on multiple projects
without requalification
Additional protection increases
system reliability
• Reverse-current protection
• Short-circuit protection
• Thermal-shutdown protection
