TSC1031 is a high-voltage, high-side current sense amplifier with independent supply and input common-mode voltages, wide common-mode operating range and surviving range, low current consumption, pin selectable gain, and EMI filtering. It is suitable for automotive current monitoring, DC motor control, photovoltaic systems, battery chargers, etc.
The TSC1031 is a high-voltage, high-side current sense amplifier designed to measure small differential voltages on shunt resistors. It translates these signals into ground-referenced output voltages suitable for various applications including automotive monitoring, DC motor control, and photovoltaic systems.
Key features include an independent supply and input common-mode voltage range, supporting up to 70 V in single-supply configurations or -2.1 V to 65 V in dual-supply modes. The device offers pin-selectable gain options of 50 V/V or 100 V/V, buffered output, and EMI filtering capabilities. It operates with low current consumption (max 360 µA) across a wide temperature range from -40°C to +125°C.
| Input common-mode range (single supply) | 2.9 V to 70 V |
|---|---|
| Supply voltage range (single supply) | 2.7 V to 5.5 V |
| Total supply current (typical) | 360 µA |
| Selectable gain options | 50 V/V or 100 V/V |
| Operating temperature range | -40 to +125 °C |
The device supports a wide common-mode operating range of up to 70 V in single-supply configuration.
The gain is adjustable to either 50 V/V or 100 V/V by selecting a specific pin.
The TSC1031 is available in TSSOP8 and SO-8 plastic packages.
