The STMicroelectronics TSC215ICT is a single-channel current sense amplifier in a SC-70-6 package, built for low-side or high-side shunt monitoring where the signal bandwidth stays below 60 kHz. That gain-bandwidth product sets the upper frequency it can accurately amplify — useful for tracking DC load changes or low-frequency ripple, but not for fast-switching waveforms above a few tens of kHz. The 0.42 V/µs slew rate matches that bandwidth; expect clean reproduction of signals up to about 10 kHz with minimal phase lag.
65 µA supply — the always-on angle
Quiescent current of 65 µA makes this part a fit for battery-powered systems where the sense amplifier stays active continuously — think portable instrumentation, IoT edge nodes, or automotive body controllers that must not drain the standby battery. The 28 µA input bias current is the price of that low-power bipolar input stage; it flows through the shunt resistor and adds a small offset voltage that must be accounted for in the measurement budget, especially with high-value shunt resistors.
Package and mounting
Housed in the SC-70-6 (also known as 6-TSSOP or SOT-363), the TSC215ICT is a surface-mount device with a 1.25 mm body width — a footprint that fits dense mixed-signal boards. The tiny pad pitch means a well-defined solder stencil and a clean reflow profile are needed to avoid bridging.
