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.

BQ3287EMT General Description

The CMOS bq3287E/bq3287EA is alow-power microprocessor periph-eral providing a time-of-day clockand 100-year calendar with alarmfeatures and battery operation.Otherfeaturesincludethreemaskable interrupt sources, square-wave output, and 242 bytes of gen-eralnonvolatilestorage.A32.768kHz output is available forsustaining power-management ac-tivities.Wake-up capability is pro-vided by an alarm interrupt, which isactive in battery-backup mode.Thebq3287EA version is identical to thebq3287E, with the addition of theRAM clear input.The bq3287E is a fully compatiblereal-time clock for IBM AT-compatiblecomputers and other applications. Thebq3287E write-protects the clock, cal-endar, and storage registers duringpower failure. The integral backup en-ergy source then maintains data andoperates the clock and calendar.As shipped from Benchmarq, thereal time clock is turned off to maxi-mize battery capacity for in-systemoperation.The bq3287E is functionally equiva-lent to the bq3285E, except the bat-tery (16,20) and crystal pins (2,3)are not accessible. These pins areconnected internally to a coin celland quartz crystal. The coin cell issized to provide 10 years of data re-tention and clock operation in theabsence of power.
