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.

Quality Guarantee

The NXP® MC33972ATEKR2 multiple switch detection interface with suppressed wake-up is designed to detect the closing and opening of up to 22 switch contacts.

The switch status, either open or closed, is transferred to the MCU through a SPI
Features a 22-to-1 analog multiplexer for reading inputs as analog. The analog input signal is buffered and provided on the AMUX output pin for the MCU to read
Two modes of operation:
- Normal: allows programming of the device and supplies switch contacts with pull-up or pull-down current monitoring switch change of state
- Sleep: provides low quiescent current, making MC33972ATEKR2 ideal for automotive and industrial products requiring low sleep state currents

Feature

Interfaces directly to microprocessor using 3.3 V / 5.0 V SPI protocol
Selectable wake-up on change of state
Eight programmable inputs (switches to battery or ground)
Fourteen switch-to-ground inputs
Active Interrupt (INT) on change-of-switch state
Switch Voltage Range -14 – VPWR
Operating Voltage 5.5 V – 26 V (VPWR)
This product is included in NXP®.s product longevity program, with assured supply for a minimum of 15 years after launch
