What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

The TCA9517is abidirectional buffer with level shifting capabilities for I2C and SMBussystems. It provides bidirectional voltage-level translation (up-translation/down-translation)between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-modeapplications. This device enables I2C and SMBus systems to be extendedwithout degradation of performance, even during level shifting.

The TCA9517buffersboth the serial data (SDA) and the serial clock (SCL) signals on the I2Cbus, thus allowing two buses of up to 400-pF bus capacitance to be connected in anI2C application.

The TCA9517has twotypes of drivers: A-side drivers and B-side drivers. All inputs and I/Os are over-voltage tolerantto 5.5 V, even when the device is unpowered (VCCB and/orVCCA = 0V).

The type of buffer design on the B-sideprevents it from being used in series with devices which use static voltage offset. This is becausethese devices do not recognize buffered low signals as a valid low and do not propagate it as abuffered low again.

The B-side drivers operate from 2.7V to 5.5V. The output low level for this internalbuffer is approximately 0.5V, but the input voltage must be 70mV or more below the output lowlevel when the output internally is driven low. The higher-voltage low signal is called a bufferedlow. When the B-side I/O is driven low internally, the low is not recognized as a low by the input.This feature prevents a lockup condition from occurring when the input low condition is released.

The A-side drivers operate from 0.9V to 5.5V and drive more current. They do notrequire the buffered low feature (or the static offset voltage). This means that a low signal onthe B-side translates to a nearly 0 V low on the A-side, which accommodates smaller voltage swingsof lower-voltage logic. The output pulldown on the A-side drives a hard low, and the input level isset at 0.3 ×VCCA to accommodate the need for a lower low level in systemswhere the low-voltage-side supply voltage is as low as 0.9V.

The A-side of two or more TCA9517DGKR s can be connected together, allowing many topographies (SeeFigure 8 andFigure 9 ), with the A-side as the common bus.Also, the A-side can be connected directly to any other buffer with static- or dynamic-offsetvoltage. Multiple TCA9517DGKR s canbe connected in series, A-side to B-side, with no buildup in offset voltage and with onlytime-of-flight delays to consider. The TCA9517cannot be connected B-side to B-side, because of the buffered lowvoltage from the B-side. The B-side cannot be connected to a device with rise time accelerators.

VCCA is only used to provide the 0.3 × VCCA reference to theA-side input comparators and for the power-good-detect circuit. The TCA9517logic and all I/Os arepowered by the VCCB pin.

As with the standard I2C system, pullup resistors are requiredto provide the logic-high levels on the buffered bus. The TCA9517DGKR has standard open-drain configuration of theI2C bus. The size of these pullup resistors depends on the system, buteach side of the repeater must have a pullup resistor. The device is designed to work with Standardmode and Fast mode I2C devices in addition to SMBus devices. Standardmode I2C devices only specify 3mA in a genericI2C system, where Standard mode devices and multiple masters arepossible. Under certain conditions, higher termination currents can be used.
