FEATURES
DESCRIPTION
The TMP421, TMP422, and TMP423 are remote
234
SOT23-8 and DSBGA (WCSP) PACKAGES
temperature sensor monitors with a built-in local
±1°C REMOTE DIODE SENSOR (MAX)
temperature sensor. The remote temperature sensor
±1.5°C LOCAL TEMPERATURE SENSOR (MAX)
diode-connected transistors are typically low-cost,
NPN- or PNP-type transistors or diodes that are an
SERIES RESISTANCE CANCELLATION
integral part of microcontrollers, microprocessors, or
n-FACTOR CORRECTION
FPGAs.
TWO-WIRE/ SMBus™ SERIAL INTERFACE

manufacturers, with no calibration needed. The two-
DIODE FAULT DETECTION
wire serial interface accepts SMBus write byte, read
byte, send byte, and receive byte commands to
RoHS COMPLIANT AND NO Sb/Br
configure the device.
APPLICATIONS
The TMP421, TMP422, and TMP423 include series
resistance cancellation, programmable non-ideality

factor, wide remote temperature measurement range
MONITORING
(up to +150°C), and diode fault detection.
LCD/ DLP®/LCOS PROJECTORS
The TMP421, TMP422, and TMP423 are all available
SERVERS
in a SOT23-8 package. The TMP421C is also
CENTRAL OFFICE TELECOM EQUIPMENT
available in a DSBGA (WCSP) package.
