PCA9548APW Datasheet PDF – 8-Channel I2C-Bus Switch

Posted on by pinout

Part Number: PCA9548APW

Function: 8-channel I2C-bus switch with reset

Package: SO, TSSOP, HVQFN 24 Pin Type

Manufacturer: NXP Semiconductors.

Pinouts:
PCA9548APW datasheet

Description

The PCA9548APW is an octal bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register.

An active LOW reset input allows the PCA9548A to recover from a situation where one of
the downstream I2C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets
the I2C-bus state machine and causes all the channels to be deselected as does the
internal Power-on reset function.

Features

1. 1-of-8 bidirectional translating switches

2. I2C-bus interface logic; compatible with SMBus standards

3. Active LOW reset input

4. Three address pins allowing up to eight devices on the I2C-bus

5. Channel selection via I2C-bus, in any combination

6. Power-up with all switch channels deselected

TPS92411 Datasheet PDF – Floating Switch for Offline AC Drive

Posted on by pinout

Part Number: TPS92411

Function: Floating Switch for Offline AC Linear Direct Drive of LEDs with Low Ripple Current.

Package: HSOIC 8 Pin, SOT-23 Type

Manufacturer: Texas Instruments

Pinouts:

TPS92411 datasheet

 

Description

The TPS92411 is a 100-V floating MOSFET switch for use in offline LED lighting applications. It is used in conjunction with a current regulator that can achieve greater than 0.9 power factor to create a LED drive solution with low-ripple current. When properly designed, solution performance is comparable to traditional flyback, buck or boost based AC/DC LED drivers. The approach requires no inductive components saving size and cost. Slew controlled low frequency operation of the TPS92411 switches creates very little EMI. Detailed operation is described in the section.

 

Features

 

  • High-Performance Solution for Driving LEDs from AC Mains
  • Simplifies Design of Phase Dimmable LED Driver with High
    Power Factor,
    Low Total Harmonic Distortion, and Low Current Ripple
  • Suitable for LED Lamp and Luminaires up to 70 W
  • Input Voltage Range: 7.5 V to 100 V
  • Stackable 100V, 2-Ω MOSFET Building Block
  • Up to 350 mA Current Capability (PSOP package)
  • Controlled Switch Open and Close Transitions Minimize EMI
