SGM4547
SGM4547 is High Speed Piezo-Sounder and Ultra-Sound Transducer Driver manufactured by SG Micro.
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 piezosounder 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℃.
