TSC2011IST
Overview
The TSC2011IST is a high-side bidirectional current sense amplifier designed to measure small differential voltages across a shunt resistor over a wide common-mode range of -20V to +70V. Operating from a supply voltage of 2.7V to 5.5V, it provides a high-precision analog output with a gain of 60V/V. The device includes a shutdown mode that reduces current consumption to 20uA, making it suitable for power-sensitive applications.
Why Choose This Part
The TSC2011IST offers excellent robustness with a wide input common-mode range that tolerates negative voltages down to -20V, protecting against inductive kickback. It features a low input offset voltage of 500uV and high accuracy of 0.1 percent, ensuring reliable measurements even at low sense currents. The 750kHz bandwidth and 3.5V/us slew rate allow for fast transient response in dynamic load environments.
Applications
Key Specifications
Getting Started
To evaluate this part, design a PCB with a low-inductance Kelvin-connection layout for the shunt resistor to maintain measurement accuracy. Connect the SHDN pin to a microcontroller GPIO to manage power consumption during idle states. Ensure the VDD supply is bypassed with a 0.1uF ceramic capacitor placed close to the IC pins.
