The 450 kHz -3 dB bandwidth gives this part enough speed to track current waveforms in switching power supplies and motor-drive phases running at several hundred kilohertz. The 0.9 V/µs slew rate means the output can follow fast current transients — think load dumps or short-circuit events — without excessive delay. For a typical 10 mΩ shunt, the 200 µV input offset translates to a 20 mA DC error at the sense point, which is acceptable for most automotive load monitoring and overcurrent detection loops. ## Package and mounting for the SOT-23-5 footprint The TSC101CIYLT comes in a SOT-23-5 package (SC-74A, SOT-753) rated for surface-mount assembly. The five-pin footprint is common and easy to route: the shunt inputs, supply, ground, and output fit on a tight PCB without needing a dedicated sense amplifier layer. The 60 mA output per channel can drive the ADC input of a microcontroller or an external comparator directly. The AEC-Q100 qualification means the part has passed the full suite of automotive stress tests — temperature cycling, HBM ESD, latch-up, and life test — and is supported by PPAP documentation that an OEM auditor will ask for.","metaTitle":"ST TSC101CIYLT Current Sense Amplifier, AEC-Q100, SOT-23-5","metaDescription":"ST TSC101CIYLT automotive current sense amplifier, AEC-Q100 qualified, 450 kHz bandwidth, 0.9 V/µs slew rate, -40°C to 125°C, SOT-23-5.
