  RE: INA200: Resistor and FET selection for High side overcurrent shutdown

  Hi Satoshi, R1 and R2 are determined by the ratio between comparator threshold (0.6V) and INA201 output voltage at desired trip point (0.5A*100mOhm*50=2.5V). The relationship is R2/(R1+R2)=0.6/2.5. We can choose R1 to be 19K; R2=6K. R4 can generally...

  RE: INA200-Q1: INA200-Q1 output when negative load current

  Hello Koji, This is not the case and it depends on the Supply voltage and the Common mode voltage. The INA200,INA201 and INA202 may not work as expected when the vsense voltage is below 20mV . See section 10.1.4 Accuracy Variations as a Result of...

  RE: INA201: INA201 output accuracy

  Hi Roger and Kai, For the low Vsense case 2, output of the amplifier is unpredictable. For normal operation – once your Vs ramps and Vcm is on – it seems like you are operating in Low Vsense Case 3 (Vsense = ~15mV, Isense = ~1.5A). To answer your...

  RE: INA202: Is there an EVM for this device?

  Hello Roy, Thanks for reaching out on the forum. There is an EVM. However, it is called the INA200EVM. The INA200, INA201, and INA202 fall under the same family with the same package and should have the same silicon with the exception being the internal...
