• ±1°C REMOTE DIODE SENSOR
The TMP435 is a remote temperature sensor monitor
with a built-in local temperature sensor. The remote
• ±1°C LOCAL TEMPERATURE SENSOR
temperature sensor diode-connected transistors are
• AUTOMATIC BETA COMPENSATION
typically low-cost, NPN- or PNP-type transistors or
• n-FACTOR CORRECTION
diodes that are an integral part of microcontrollers,
• PROGRAMMABLE THRESHOLD LIMITS microprocessors, or FPGAs.
• TWO-WIRE/ SMBus™ SERIAL INTERFACE
Remote accuracy is ±1°C for multiple IC
manufacturers, with no calibration needed. The
• MINIMUM AND MAXIMUM TEMPERATURE
two-wire serial interface accepts SMBus write byte,
MONITORS
read byte, send byte, and receive byte commands to
