In a 400 kHz switching converter, the amplifier still has enough gain to resolve the inductor current waveform for overcurrent detection or average-current-mode control. If the switching frequency pushes above 500 kHz, the gain roll-off will attenuate the signal — budget a faster current sense (e.g., 1 MHz or higher) for those rails. ## Package and footprint for the 8-MiniSO The TSC2012IYST comes in an 8-MiniSO package (also listed as 8-TSSOP, 8-MSOP with 0.118\" body width, 3.00 mm). Surface-mount only. The 8-MiniSO footprint is shared across several ST current-sense amplifiers, so a layout designed for the TSC2012 can often accept a pin-compatible sibling without a board spin. No exposed pad — thermal dissipation goes through the leads and PCB copper.","metaTitle":"TSC2012IYST Current Sense Amplifier, AEC-Q100, 490 kHz","metaDescription":"STMicroelectronics TSC2012IYST automotive current sense amplifier, AEC-Q100, 490 kHz bandwidth, 5.2 V/µs slew rate, -40°C to 125°C, 8-MiniSO package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"5.2V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"490 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.6mA","Number of Circuits":"1","Current - Input Bias":"350 µA","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Input Offset":"500 µV","Supplier Device Package":"8-MiniSO","Current - Output / Channel":"36 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.96000","currency":"USD"},{"qty":10,"price":"$3.55800","currency":"USD"},{"qty":25,"price":"$3.36400","currency":"USD"},{"qty":100,"price":"$2.91550","currency":"USD"},{"qty":250,"price":"$2.76600","currency":"USD"},{"qty":500,"price":"$2.48192","currency":"USD"},{"qty":1000,"price":"$2.46838","currency":"USD"},{"qty":4000,"price":"$2.46838","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3ba0d695c9704e966fcc55dde068cbc1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives or equivalents for TSC2012IYST?","answer":"The TSC200IDT is a functional peer within the same current-sense amplifier family, though it uses an open-drain output and has a different bandwidth/slew-rate profile.
