SGM4546
Dual-Channel, High Speed,
High SPL Piezo-Sounder Driver
GENERAL DESCRIPTION
FEATURES
The SGM4546 is matched dual-channel high speed,
high sound pressure level (SPL) piezo-sounder 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
● Power Supply Voltage Range: 1.8V to 5.5V
● High Speed Driver
● Very Short Rise Time and Fall Time
● Improved Response Times
To reduce problems with time and clock skew,
SGM4546 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, boost DC/DC is integrated to provide high
driven voltage. The tiny packages make 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 Green TSSOP-16 (Exposed Pad)
and TDFN-3×3-14L Packages
The SGM4546 is available in Green TDFN-3×3-14L
and TSSOP-16 (Exposed Pad) packages. It operates
over an ambient temperature range of -40℃ to +85℃.

Package Thermal Resistance
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
