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.

MIC38HC42-1YM-TR General Description

The MIC38HC4x family are fixed frequency current-modePWM controllers with 1A drive current capability. Micrel’sBiCMOS devices are pin-compatible with 384x bipolar de-vices. Their high output drive, with fast rise and fall times,combined with low startup current make it an ideal PWMcontroller where high efficiency is required.Undervoltage lockout circuitry allows the ’42 and ’44 versionsto start up at 14.5V and operate down to 9V, and the ’43 and’45 versions start at 8.4V with operation down to 7.6V. Allversions operate up to 20V.When compared to bipolar UC384x devices operating from a15V supply, start-up current has been reduced to 50µAtypical and operating current has been reduced to 4.0 mAtypical. Decreased output rise and fall times drive largerMOSFETs, and rail-to-rail output capability increases effi-ciency, especially at lower supply voltages. The MIC38HC4xalso features a trimmed oscillator discharge current andbandgap reference.MIC38HC4x-1 is available in 14-pin plastic DIP and SOICpackages. 8-pin devices feature small size, while 14-pindevices separate the analog and power connections forimproved performance and power dissipation.
