SGM447
1.5V Dual-Gain Analog Temperature Sensor
with Class-AB Output
GENERAL DESCRIPTION
FEATURES
The SGM447 is a high-accuracy analog output CMOS
integrated-circuit temperature sensor with tiny WLCSP
package. It can operate with a supply voltage of 1.5V in
the lowest gain configuration while measuring the
temperature of -55℃ to +150℃.
● Power Supply Voltage: 1.5V to 5.5V
● Low Quiescent Current
● Temperature Accuracy:
-20℃ to +85℃: ±2.5℃ (MAX)
-55℃ to +150℃: ±3.5℃ (MAX)
● Two Selectable Gains
The SGM447 is capable of strong output source and
sink current while driving heavy loads in that it has
class-AB output. Therefore, it is available for sourcing the
input of a sample-and-hold analog-to-digital converter
requiring transient load. Without using external
components such as resistors and buffers on the output,
the SGM447 can deliver the output voltage inversely
proportional to measured temperature from -55℃ to
+150 ℃ . Low supply current makes it suitable for
application in general temperature sensors and
battery-powered systems.
● 300μA (MAX) Source Current
● Push-pull Output
● Output Short-Circuit Protection
● Operating Temperature Range: -55℃ to +150℃
● Available in a Green WLCSP-0.8×0.8-4B-A

APPLICATIONS
Temperature Sensing and Compensation
Battery Management
Automotive Equipment
The gain of the temperature-to-voltage output transfer
function is set by the gain selection input (GS) pin with
two selectable slopes, (-5.4mV/℃ at GS = 0 or -8.1mV/℃
at GS = 1). If the GS pin is connect to logic high, the
transfer function will achieve the maximum temperature
sensitivity gain. The GS pin can be connected to VDD
or GND without any components such as pull-up or
pull-down resistors to minimize the board area. During
operation or system diagnostics, if the input is driven by
a logical signal, then the system will optimize the gain.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
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

ESD Susceptibility
ESD SENSITIVITY CAUTION
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.

DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
NOTE:
1. When the input voltage (VIN) at any pin exceeds power
supplies (VIN < GND or VIN > V+), the current at that pin
should be limited to 5mA.
