BQ34Z100-G1: Temperature sensor.

Part Number: BQ34Z100-G1

Dear all

When I use bq34z100-g1 to read the temperature, when the thermistor value changes, the temperature value would be delayed to change, the delay time varies from 7s to 15s. Why ?

I had used EV2300 tool,used adjustable resistance to simulate thermistor.

Hi Went,

If the evm is in sleep, then you will have updates every 20s. If the evm has current greater than sleep current, the ADC measurements are taken every second and it will update within 2 to 3 seconds.

Dear Batt

No,I don't use EVM, I used the device on my board.

Hi Went,

Then you need to stop comms to the i2c lines to enable the gauge to sleep when there is no current.

Dear Batt

Could you share me with detail stop comms ? I can not find the detail action.

Hi Went,

What i mean is that you need to stop communicating on the i2c bus or float the i2c lines. When there is no communication with the gauge and there is no current, the gauge will enter sleep mode.
