Part Number: TMP421-Q1 Other Parts Discussed in Thread: SYSCONFIG Hi,
I am Yonghee Lee and working as a software engineer at LG Innotek.
I am going to use TMP421AQDCNRQ1 Temperature Sensor via I2C.
The first thing that I want to ask is how to set the…
Part Number: TMP421-Q1 Hi Team,
My customer are request the IBIS or IBIS AMI model for some parts, can you provide its ?
Part number: TMP421AQDCNTQ1
Thanks & regards,

Part Number: TMP421-Q1 Hi Team, Our customer use the TMP421-Q1 parts in a very noisy application, where floating pins are not allowed. Is it possible to use an external resistor divider to manage the FLOAT adressing mode? They use the FLOAT (1.65V) level…
Part Number: TMP421-Q1 Other Parts Discussed in Thread: DXP I am reading xC0 00 from the external 2N3906 transistor. Connected as shown on page 1 of the data sheet with the emitter grounded at the remote location. The internal reading seems to be correct…
Part Number: TMP421-Q1 Other Parts Discussed in Thread: TMP421 Hi,
The TMP421 description is I2C/SMBus Temperature Sensor. My question is, can the TMP421 work on the same I2C bus as an AT24CM02 EEPROM?
As far as i can tell the EEPROM's address (0xA4)…
The schematic shown for LM95233 and ADC12QJ1600 features the ADC connected as remote temperature channel 1. The NPN, Q1, is connected as channel 2. The Q1 device is not necessary to measure the temperature of the ADC. In fact, a 2nd ADC could be connected…
If both of your TMP421's address pins were grounded, you could drop-in a TMP422 or TMP442. If your remote junction's return (DXN) is grounded and TMP421's A0 is grounded, you could use a TMP423. You could use the automotive grade (Q1) of any of these…
Hi Eddie,
I tested your customer's setup and got the addresses shown below (0x4E and 0x4D) for each TMP422-Q1.
Also, if your customer is only planning on using one channel, our TMP421-Q1 may be a good solution as it has one channel and two dedicated…
