Maximizes Output Transmit Power and Consumes the Lowest Supply Current

   

The MAX7049 high-performance, single-chip, ultra-low-power ASK/FSK UHF transmitter operates in the industrial, scientific, medical (ISM) band at 288MHz to 945MHz carrier frequencies. The IC also includes a low phase noise fractional-N synthesizer for precise tuning, fast frequency agility, and low out-of-band power. To support narrow-band applications, the IC has both amplitude-shaping and frequency-shaping functions that enable the user to optimize spectral efficiency. The IC offers Tx power up to +15dBm. These features make the transmitter ideally suited for long-range applications.

Network-attached USB hubs

  1. Access and monitor USB and serial devices over TCP/IP network
  2. Works with existing POS or other application software
  3. Excellent in virtualized environments such as VMware®
  4. Creates systems redundancy and increases security
  5. Simplifies operations and reduces IT support
  6. Available in 2, 5 and 14 USB ports versions

AnywhereUSB products are network-attached USB hubs that connect USB peripheral devices to a PC over a Local Area Network. The AnywhereUSB TS model also adds four RS-232 serial ports, enabling the mixing of USB and serial ports over the same network connection. Relocating the host PC to a remote location translates to smaller workstations, enabling deployment without a local PC in kiosks, ATMs, restaurant kitchens, manufacturing lines or any hostile or non-secure area where having a local PC is not practical.

APPLICATION NOTES
 

Accurate High-Side Current-Sense Amplifier Monitors PWM Load Current

Accurate high-side current sensing is essential for automotive control systems such as electric power steering, automatic gear shifting, transmission control, engine fuel-injection control, valve control in braking, and active suspensions. All of these applications require precise regulation of the current through a motor or solenoid, to control either the torque of the motor or the drive of the solenoid. The circuit presented in this article includes a precision, high-side current-sense amplifier (MAX9918) for monitoring inductive load currents over a wide range of input common-mode voltages. It is suitable for applications in which the input common voltage can become negative due to inductive kick-back, reverse-battery conditions, or transient events.
