Automotive current-sense amp in TSOT-23-8
It measures current across a shunt resistor with a very low 3 µV input offset voltage, enabling accurate readings at millivolt-level drops. Its 27 kHz bandwidth covers DC/DC converter loop control and motor-phase current regulation. The TSOT-23-8 package fits compact ECU and battery-management PCBs.
The 27 kHz gain-bandwidth product sets the practical upper frequency for accurate current measurement. For a typical 10 mΩ shunt, this amp can resolve current changes up to a few kilohertz — adequate for monitoring inductor current in a 400 kHz switching regulator or for reading motor phase current at commutation rates. It will not track fast transients in a GaN-based converter or high-speed solenoid drive; those need a wider-bandwidth current-sense amp like the INA254A1IPWAR (350 kHz).
It can handle the thermal cycling and high ambient temperatures found in engine control units, transmission controllers, and battery junction boxes. The TSOT-23-8 package with surface-mount footprint is standard for automated assembly lines.
