DESCRIPTION

The TMP435 is a remote temperature sensor monitor

with a built-in local temperature sensor. The remote

temperature sensor diode-connected transistors are

typically low-cost, NPN- or PNP-type transistors or

diodes that are an integral part of microcontrollers,

microprocessors, or FPGAs.

Remote accuracy is ±1°C for multiple IC

manufacturers, with no calibration needed. The

two-wire serial interface accepts SMBus write byte,

read byte, send byte, and receive byte commands to program the alarm thresholds and to read

temperature data.

The TMP435 includes beta compensation

(correction), series resistance cancellation,

programmable non-ideality factor, programmable

resolution, programmable threshold limits, minimum

and maximum temperature monitors, wide remote

temperature measurement range (up to +150°C),

diode fault detection, a temperature alert function,

and pin-programmable two-wire addressing using

3-state logic.

The TMP435 is available in an MSOP-10 package.
