SGM4547

High Speed Piezo-Sounder and

Ultra-Sound Transducer Driver

GENERAL DESCRIPTION

FEATURES

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.

● Integrated Boost DC/DC to Achieve 26V (MAX)

Driven Voltage

● 2A Peak Driven Current to Drive Capacitive Loads

● Wide Operating Voltage Range

● High Speed Driver

● Very Short Rise Time and Fall Time

● Improved Response Times

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.

● Matched Rise Time and Fall Time

● Independent Enable Control for Each Channel

● Reduced Clock Skew between Dual Channels

● Output is at Low under UVLO Protection,

Enable Pin Floating or Disable Status

● High Noise Immunity

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.

● Improved Clocking Rate

● Low Supply Current and Output Impedance

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green TDFN-3×3-14L Package

The SGM4547 is available in a Green TDFN-3×3-14L

package. It operates over an ambient temperature

range of -40℃ to +85℃.
