BQ51050B datasheet

 

Description

The bq5105x, BQ51050B is a high efficiency, wireless power receiver with Li-Ion/Li-Pol battery charge controller for portable applications. The bq5105x device provides efficient AC/DC power conversion, integrates digital controller required to comply with Qi v1.1 communication protocol and all necessary control algorithms needed for efficient and safe Li-Ion and Li-Pol battery charger. Together with bq500210 transmitter-side controller, the bq5105x enables a complete wireless power transfer system for direct battery charger solution. By utilizing near-field inductive power transfer, the receiver coil embedded in the portable device can pick up the power transmitted by transmitter coil. The AC signal from the receiver coil is then rectified and conditioned to apply power directly to the battery. Global feedback is established from the receiver to the transmitter in order to stabilize the power transfer process. This feedback is established by utilizing the Qi v1.1 communication protocol.

Applications

• Battery Packs
• Cell Phones and Smart Phones
• Headsets
• Portable Media Players
• Other Handheld Devices

DS3486MX Datasheet – Quad RS-422, RS-423 Line Receiver

Posted on by pinout

Part Number: DS3486MX

Function: Quad RS-422, RS-423 Line Receiver

Package: DIP, SOP 16 Pin type

Manufacturer: Texas Instruments

Pinouts:

DS3486MX datasheet

 

Description

Texas Instruments’ quad RS-422, RS-423 receiver features four independent receivers which comply with EIA Standards for the electrical characteristics of balanced/unbalanced voltage digital interface circuits. Receiver outputs are 74LS compatible, TRI-STATE structures which are forced to a high impedance state when the appropriate output control pin reaches a logic zero condition. A PNP device buffers each output control pin to assure minimum loading for either logic one or logic zero inputs. In addition, each receiver has internal hysteresis circuitry to improve noise margin and discourage output instability for slowly changing input waveforms.

Features

• Four Independent Receivers
• TRI-STATE Outputs
• Internal Hysteresis −140 mV (typ)
• Fast Propagation Times −19 ns (typ)
• TTL Compatible Outputs
• 5V Supply
• Pin Compatible and Interchangeable with MC3486
