TSC102IYPT

Instrumentation, Op Amps, Buffer Amps Overview

The TSC102IYPT is a high-side current sense amplifier with integrated signal conditioning, manufactured by STMicroelectronics. It measures differential voltage across a shunt resistor and provides a ground-referenced output. Key electrical parameters include a common-mode operating range of 2.8 V to 30 V and a survival range from -16 V to 60 V. The device features a maximum input offset voltage of 1.5 mV at 25°C and operates with a quiescent current lower than 420 μA. It supports an independent supply voltage between 3.5 V and 5.5 V, offers 4 kV ESD protection, and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IYPT' against the official STMicroelectronics datasheet to confirm package type (TSSOP8) and industrial temperature grade. Ensure compatibility with the required common-mode voltage levels and supply constraints before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a high-side current sensor with low quiescent current and wide common-mode range is required. The integrated signal conditioning amplifier allows for tailored output adjustments. Consider the TSSOP8 package size for space-constrained designs. Verify that the 420 μA current consumption fits the system's power budget and that the 2.8 V to 30 V common-mode range covers the application's operational voltages.

Instrumentation, Op Amps, Buffer Amps Part Context

The TSC102 belongs to STMicroelectronics' family of high-side current sense amplifiers designed for automotive and industrial environments. It distinguishes itself by combining current sensing with an additional operational amplifier for signal conditioning. This integration reduces component count and board space compared to discrete solutions. The device is engineered to withstand harsh automotive conditions, including reverse battery and load-dump events.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the official STMicroelectronics documentation for direct pin-compatible alternatives within the TSC series. Verify that any substitute maintains the same independent supply architecture and common-mode voltage specifications. Ensure the replacement meets the required ESD protection levels and temperature range for automotive reliability.
