The TSC103 is a high-voltage, high-side current sense amplifier with independent supply and input common-mode voltages, wide common-mode operating range, low current consumption, pin selectable gain, and buffered output.
The TSC103 is a high-voltage, high-side current sense amplifier designed to measure small differential voltages on shunt resistors. It features an independent supply and input common-mode voltage, allowing operation in both single-supply (2.9 V to 70 V) and dual-supply configurations (-2.1 V to 65 V). The device offers four selectable gain settings (20 V/V, 25 V/V, 50 V/V, or 100 V/V) via digital pins.
| Input common-mode range (single-supply) | 2.9 to 70 V |
|---|---|
| Supply voltage range (single-supply) | 2.7 to 5.5 V |
| Total supply current (typical) | 360 nA |
| Selectable gains | 20, 25, 50, or 100 V/V |
| Operating temperature range | -40 to 125 °C |
The input common-mode voltage ranges from 2.9 V to 70 V.
The gain is selectable via two digital input pins, SEL1 and SEL2.
It is used in automotive current monitoring, DC motor control, and photovoltaic systems.
