INA3221AIRGVT Overview


There is an inclusion of buck boost converter in the package Tape & Reel (TR).A package in the way of 16-VQFN Exposed Pad is used for voltage regulator.Surface Mount is used to mount this current regulator on the board.The operating temperature should not exceed -40°C~125°C.As far as input voltage goes, current regulator supports the value of 0V~26V.As well as 16 terminations, there are also 16 terminations, which are the practice of terminating a transmission line with a voltage regulator that matches the characteristic impedance of the transmission line.As part of the INA3221 family, current regulator belongs to this class.Several pronged contacts are used in computer interfaces as 16 pins.As long as the constant current is powered by a 3.3VV power source, it should work as long as it is plugged in.This power converter employs an analog IC called POWER SUPPLY SUPPORT CIRCUIT.In terms of channel number, I would say that it is growing strongly/weakly: 1.A maximum supply voltage of 5.5V can be supported by it.There is a part called Power Management Circuits which contains all of these current regulations.As a result, it operates at the minimal supply voltage of 2.7V.It reaches 350μA when the operating supply current is supplied for its operation.In order for current regulation to operate, current regulation requires 3.3V power supplies.As well as RESET THRESHOLD VOLTAGE IS 2V, constant current regulator has another characteristic.With 450μA's maximal supply current, there is a great deal of current regulator's design flexibility.In spite of external influences, it consumes 350μA tones of quiescent current per second.
