Dedicated current-sense amplifier in a tiny SC-70-6
The STMicroelectronics TSC210IYCT is a single-channel current-sense amplifier designed to measure current by sensing the voltage drop across a shunt resistor. The supply span from 2.7 V to 26 V means it can run directly off a 3.3 V logic rail or a 24 V industrial bus without an intermediate regulator, which simplifies the power tree.
For a current-sense application, this means the TSC210IYCT can accurately reproduce DC shunt voltages and low-frequency ripple (say, 50/60 Hz line monitoring or PWM current at a few kHz), but it will start to roll off well before any switching-node edge rates. If your design needs to capture sub-microsecond current spikes or high-frequency load transients, you would look at a faster part like the TSC212ICT with its 0.5 V/µs slew rate. For steady-state current monitoring, battery charge/discharge tracking, or overcurrent detection in motor drives, the 25 kHz bandwidth is adequate and the low 65 µA supply current keeps the quiescent overhead minimal.
Supply voltage range: 2.7 V to 26 V — one part for multiple rail voltages
The wide supply span from 2.7 V to 26 V is the standout feature for BOM consolidation. It covers 3.3 V and 5 V logic rails, 12 V automotive battery lines, and 24 V industrial supplies without a secondary regulator. The input offset voltage is rated at 35 µV, which, combined with the 28 µA input bias current, gives good DC accuracy for low-side or high-side sensing as long as the shunt voltage is in the tens of millivolts range. The 65 µA supply current makes it viable for always-on monitoring in battery-powered equipment.
Package and footprint: SC-70-6
The TSC210IYCT comes in a 6-lead SC-70 package (also known as SOT-363), with the supplier device package designated SC-70-6. It is a surface-mount part, so the board layout needs the standard 0.65 mm pitch footprint. The small body saves board area — useful when you are packing multiple current-sense channels into a dense design. The shipping options are Tape & Reel or Cut Tape, which suits both prototyping and production pick-and-place.
