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.

Description

The TPS3305-18DGNR family is a series of micropower supply voltage supervisors designed for circuit initialization, primarily in DSP and processor-based systems, which require two supply voltages.
The product spectrum of the TPS3305-18DGNR is designed for monitoring two independent supply voltages of 3.3 V/1.8 V, 3.3 V/2.5 V or 3.3 V /5 V.

The various supply voltage supervisors are designed to monitor the nominal supply voltage, as shown in the following supply voltage monitoring table.

During power-on, RESET is asserted when the supply voltage Vop becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remains below the threshold voltage ViT+
Aninternal timerdelays the returm of the RESET output to the inactive state(high) to ensure proper system reset.
The delay time, tatyo = 200 ms, starts after SENSE 1 and SENSE2 inputs have risen above the threshold voltage Vr+. When the voltage at SENSE1 or SENSE2 input drops below the threshold voltage Vrr-, the RESET output becomes active(low) again.
The TPS3305-xx devices integrate a watchdog timer that is periodically triggered by a positive or negative transition of WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, t(out)=1.6s, RESET becomes active for the time period ta. This event also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog.
The TPS3305-xx family of devices incorporates a manual reset input, MR.A low level at MR causes RESET to become active. In addition to the active-low RESET output, the TPS3305-xx family includes an active-high RESET output.
The TPS3305-xx devices are available in either 8-pin MSOP or standard 8-pin SO packages.
The TPS3305-xx family is characterized for operation over a temperature range of-40℃ to 85℃
