GENERAL DEscriptION

The SGM4547 is matched dual-channel high speed piezo-sounder and ultra-sound transducer driver which is integrated boost DC/DC to achieve high driven voltage. The unique circuit design provides excellent performance for delivering 2A peak current to highly capacitive loads.

To reduce problems with time and clock skew, SGM4547 is a good choice, with matching delays and maintaining integrity of input to output pulse-widths. Matching rise/fall delay times improve the drive capability and speed. Non-overlapping drive technology is used to minimize the dynamic switching loss.

In order to get higher volume sound from piezo-sounder and ultra-sound transducer, boost DC/DC is integrated to provide high driven voltage. The tiny package makes the device very suitable for space limited applications.

The SGM4547 is available in a Green TDFN-3×3-14L package. It operates over an ambient temperature range of -40 to +85.
