TSM102IDT

Overview

The TSM102IDT is a monolithic integrated circuit manufactured by STMicroelectronics, classified under Current Sense Amplifiers. It functions as a high-side current sensing amplifier designed for operation with common-mode voltages ranging from 2.8 V to 30 V. The device features a gain-bandwidth product of 800 kHz and offers an input bias current of 5 uA. Key electrical specifications include a maximum supply voltage of 5.5 V, a minimum operating temperature of -40 C, and a maximum operating temperature of +125 C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Monolithic integration of high-side current sensing capabilities within a single IC structure
• Operates effectively across a wide common-mode voltage range suitable for various power systems
• Designed for precision measurement applications requiring low input bias characteristics

Applications

• Power supply management systems
• Data acquisition systems
• High-side current monitoring circuits

Procurement Notes

Verify the specific ordering suffix IDT against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before finalizing procurement decisions. Cross-reference the component marking with official documentation to prevent counterfeit substitution.

Selection Notes

Select this component when a high-side current sense amplifier is required with a common-mode voltage up to 30 V. The SOIC-8 package suits space-constrained designs. Verify that the 800 kHz bandwidth meets the signal frequency requirements of the application. Confirm that the 5.5 V maximum supply voltage aligns with the system logic levels.

Part Context

The TSM102 belongs to the TSC/TSM series of analog signal conditioning devices from STMicroelectronics. This series focuses on providing integrated solutions for power management and signal processing tasks. The TSM102 specifically addresses the need for compact, cost-effective current sensing in environments where high-side measurement is necessary.

Replacement Considerations

Consult the official STMicroelectronics replacement guide or equivalent component matrix for verified cross-references. Do not assume functional equivalence with other high-side amplifiers without verifying pinout and electrical parameter alignment.
