ZHCSCV4C October 2014 – April 2021 TMP451-Q1
PRODUCTION DATA
The TMP451-Q1 device requires only a transistor connected between the D+ and D– pins for remote temperature measurement. Tie the D+ pin to GND if the remote channel is not used and only the local temperature is measured. The SDA, ALERT, and THERM pins (and SCL, if driven by an open-drain output) require pullup resistors as part of the communication bus. A 0.1-µF power-supply decoupling capacitor is recommended for local bypassing. Figure 8-1 shows the typical configuration for the TMP451-Q1 device.
