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.
