Other Parts Discussed in Thread: INA301, STRIKE
Hi,
We are using INA301-A1 in one of our designs. During design verification it is observed that the ALERT Pin transitions from HIGH to LOW when OUT pin voltage is lesser than LIMIT. The resistor value at LIMIT pin is 18k. The INA301 is powered by a 3.3V supply.
Design:
VLIMIT (typ) = 18k*80uA = 1.44V
Gain = 20
Theoretical Input voltage for ALERT to transition to low = 1.44V/20 = 72mV (Input voltage in increasing directionINA301.pdf
Practically observed Input voltage for ALERT to transition to low = 63mV
Can you please help to resolve the issue?
Best regards
Ashwin
