Texas Instruments TMCS1107EVM

Overview

TMCS1107EVM from Texas Instruments is an evaluation module designed to characterize the TMCS1107 isolated Hall-effect current sense amplifiers across all eight gain variants (A1–A4, bidirectional and unidirectional), supporting input currents up to 30 A DC with common-mode voltage tolerance up to 420 VDC, and operating from a 3–5.5-V supply.

For engineers reviewing the TMCS1107EVM datasheet, TMCS1107EVM pinout, TMCS1107EVM application, or TMCS1107EVM equivalent, this module enables rapid validation of high-side/low-side current sensing configurations, gain selection trade-offs, output filtering, and thermal behavior-critical for industrial motor drives, solar inverters, and EV on-board chargers requiring galvanic isolation and precision analog feedback.

Technical Context

The TMCS1107EVM integrates eight independent PCB segments-each populated with one TMCS1107 variant (e.g., TMCS1107A1BQDR, TMCS1107A4UQDR)-all housed on a single breakable board with standardized test points, load connectors (CB35-36-CY), and optional temperature sensor footprints (TMP235A2DBZR). Each segment shares identical circuit topology: 0.1-μF supply bypass (C2xy), 0-Ω output filter resistor (R1xy), and 10-pF filter capacitor footprint (C3xy).

It supports both high-side and low-side current measurement topologies, features dedicated IN+/IN− high-current terminals rated for 30-A DC, provides VOUT test points (TP2xy) and ground reference points (TP3xy–TP5xy), and includes J1xy headers for simultaneous VCC/VOUT/TMP monitoring-all while maintaining reinforced isolation per IEC 60747-17.

FAQ

What is the primary function of the TMCS1107EVM?

The TMCS1107EVM is an evaluation module that enables functional and performance characterization of the TMCS1107 isolated Hall-effect current sense amplifiers. It provides eight pre-configured PCB segments-each hosting one TMCS1107 variant-to validate gain selection, high-side/low-side topology, output linearity, and thermal response under real-world current and voltage conditions up to 420 VDC common-mode.

Does the TMCS1107EVM include populated TMCS1107 devices?

Yes-the TMCS1107EVM ships with all eight TMCS1107 devices pre-soldered: TMCS1107A1BQDR, TMCS1107A2BQDR, TMCS1107A3BQDR, TMCS1107A4BQDR, TMCS1107A1UQDR, TMCS1107A2UQDR, TMCS1107A3UQDR, and TMCS1107A4UQDR-each mounted on its own segment in SOIC-8 (D0008A) package, ready for immediate evaluation without assembly.

Can the TMCS1107EVM be used for high-frequency or pulsed current measurements?

Yes-the TMCS1107EVM supports transient current evaluation when configured with low-inductance interconnects (e.g., short bus bars), adequate supply headroom, and local capacitance. Its layout preserves the intrinsic bandwidth of the TMCS1107 (up to 800 kHz for A1 variants), and advanced measurement tips in the SBOU248 User's Guide detail best practices for slew-rate-limited and high-dv/dt testing.

Is the onboard temperature sensor populated on the TMCS1107EVM?

No-the TMP235A2DBZR temperature sensor (U2xy) is included in the bill of materials and has solder pads on each segment, but it is not populated by default. Users may optionally install it to monitor ambient board temperature during evaluation; however, it does not measure die temperature directly, and thermal grease + external sensor placement is recommended for accurate DUT junction estimation.

What safety precautions apply when using the TMCS1107EVM?

The TMCS1107EVM is classified as a Texas Instruments High Voltage Evaluation Module (TI HV EVM) and requires strict adherence to TI's HV safety guidelines: de-energize before probing, use insulated tools and PPE, operate only in qualified lab environments with observer presence, and never exceed 420 VDC common-mode or 30 A DC load limits. Energized boards must remain behind protective barriers with clear high-voltage signage.
