Thanks, we have solved the problem. It is the TMP05 configration mode error.
How do I trigger the SMBALERT on the ADT7470.
I want to simulate an over temp scenario.
Can I trigger the SMBALERT by writing to any of the registers?
How do I check if SMBALERT is enabled?
On the board, the ADT is hooked up to 1 temp sensor TMP05…
We are using ADT7470 device connected to 4 fans and 4 temperature sensors. Can you please provide the driver software for the device which uses I2C bus?
The ADT7470 Table 50. show "When GPIO is configured as an output, these bits are read/write. Setting these bits asserts the GPIO output. (Asserted can be high or low depending on the setting of GPIO4 polarity.)". We run below setting…
Hi ADI Experter
Does ADT7470 still support Fan spin up function?
As my customer feedback that they saw it in older version ADT7470 datasheet (Rev.B)
But they didn't see this function in the latest datasheet so they would like to confirm whether this…
I have the same problem with ADT7470 not being able to set GPIO output state, as it was already discussed at this question page - https://ez.analog.com/temperature_sensors/f/q-a/77459/adt7470-gpio-status/276442.
I've tried setting register 0x81 and…
The ADT7470 datasheet show Techx pin is Digital Input (Open Drain). I have some question as below. Could you help explain and clarify it? Thanks!
1. Digital Input (Open Drain) what kind of architecture?
2. When not use Tech3 pin, can floating…
We are using the following part in an existing design:
I would like to get clarity as to what is the maximum input voltage that the ADT7470 device is able to withstand on the SCL/SDA lines.
In the "Absolute Maximum Ratings" table…
Hello ADI support.
I need you help.
Then temperature dropped bellow Tmin and the fan controller AD7470 stops the Fan, but the Norm (bit 3 Register 0x42) doesn't asserted high) only corresponding fan[n] A 1 indicates that Fan [n] has dropped below…
