Tool/software:
Hi,
I'm using INA233 EVM (Rev.B) but i can't find any docs about EVM(Rev.B)
anyway, The experiment was organized as the block diagram below.
**POWER (9V~15V is disabled)
1. [ RESTORE_DEFAULT_ALL ]
2. [ MFR_ALERT_MASK, 0x60 ] (-> Overflow & POR is Default)
3. [ MFR_ADC_CONFIG, 0x4007 ] (Fastest, Shunt & VBus Continuous)
4.
Current_LSB = Max_Current / 2^15 = 8.192A / 2^15 = 0.00025A
CAL = 0.00512 / (Current_LSB * R_shunt) = 0.00512 / (0.00025 * 0.010) = 2048 -> 0x800
[ MFR_CALIBRATION, 0x0800 ]
5. [ CLEAR_FAULTS ] <- *Alert Assert!!
I found that the delay from Clear Fault to Alert Assistant is related to the ADC configuration.
How do I set it up?
and Is it possible to disable Overflow and POR Alert Mask?
Thanks.
