DESCRIPTION

The TMP421, TMP422, and TMP423 are remote

temperature sensor monitors 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

configure the device.

The TMP421, TMP422, and TMP423 include series

resistance cancellation, programmable non-ideality

factor, wide remote temperature measurement range

(up to +150°C), and diode fault detection.

The TMP421, TMP422, and TMP423 are all available

in a SOT23-8 package. The TMP421C is also

available in a DSBGA (WCSP) package.
