PCA9538PW I2C bus line / port of I/O of SMBus low power is patulous chip

Product model: PCA9538PW

Product brand: NXP/ favour Zhi Pu

The product encloses: TSSOP16

Product function: Port is patulous chip

PCA9538PW feature

Limits of ● wide voltage: Limits of voltage of working power source comes for 2.3V 5.5V, partial model comes for 3.0V like PCA9538PW/Q900 5.5V.

● 5V is able to bear or endure suffer I/O: I/O brings a foot to be able to be able to bear or endure voltage sufferring 5V.

● low power comsumption is characteristic: Have low need machine electricity, when resistor is being pulled to be able to maintain low n in I/O on in-house I/O great reduce power comsumption.

● clock frequency: Supportive 0Hz comes the frequency of clock of I2C bus line of 400kHz.

● ESD protects: Exceed 2000V HBM by JESD22-A114, exceed 200V MM by JESD22-A115, exceed 1000V CDM by JESD22-C101.

● encloses diversity: Outside be being enclosed except TSSOP-16, still offer SO16, HVQFN16 to enclose.

PCA9538PW explains

PCA9538PW is parts of an apparatus of a 16 CMOS that cite a base, basically use at be I2C bus line / SMBus application expands GPIO cites a base, when the I/O with the equipment additional need such as ACPI mains switch, sensor, pushbutton, LED, fan, it can offer simple and easy solution, can pass I2C interface and main control implement undertake data is exchanged, implementation brings quick control of the foot and condition to monitor to patulous I/O.

PCA9538PW applies setting

● is embedded control a system: The GPIO that is used at patulous small controller brings crural amount, satisfy the control requirement of more peripheral.

Equipment of ● industry automation: Can achieve pair of facility status monitor with control, if sensor signal is collected, relay is controlled etc.

● consumes electronic product: Commonly used wait at scanning of drive of LED indication screen, key-press, if the equipment such as sound box of intelligent hand annulus, intelligence is medium.

● electric home appliances<gj: Patulous in unit of power source management I/O, realize the control that waits to mains switch, indicator light.

● communication equipment: Use at assisting interface to expand, if control the condition indicator light of communication module, switch,wait.
