STMicroelectronics EVAL-L9907

Overview

EVAL-L9907 from STMicroelectronics is an evaluation board designed to validate the L9907 3-phase BLDC motor pre-driver IC in real-world motor control systems. It supports 6–54 V battery input, delivers up to 20 A load current, enables full SPI-based device control and diagnostics, and integrates configurable current sense amplifiers, overtemperature protection, and shoot-through prevention.

For engineers reviewing the EVAL-L9907 datasheet, EVAL-L9907 pinout, EVAL-L9907 application, or EVAL-L9907 equivalent, this board provides direct SPC560P-DISP Discovery+ compatibility, modular power MOSFET replacement (SMD or through-hole), test-point access to all signals, and USB-SPI bridge capability - critical for rapid BLDC firmware validation and gate-drive strategy development.

Technical Context

The EVAL-L9907 implements a complete hardware interface for the L9907 IC, which features six independently controllable high- and low-side pre-driver channels, programmable gate drive current levels (4 settings), and dual configurable current sense amplifiers with SPI-adjustable gain and offset. It operates across automotive-grade supply ranges (6–54 V) and supports phase-U+V or phase-U+total shunt configurations.

Board-level resources include four status LEDs (VBatt, Vcc, EN1, EN2), jumper-removable external boost components, and a standard input connector matching SPC56 Discovery boards - enabling seamless integration with LabVIEW GUI or SPC5Studio-based motor control firmware without custom adapter design.

FAQ

Is EVAL-L9907 compatible with microcontrollers other than SPC56 series?

Yes - while optimized for SPC560P-DISP Discovery+ boards via its native connector, the EVAL-L9907 exposes all SPI, PWM, EN, and ADC signals via test points and headers. Any MCU with six PWM outputs, two EN lines, two ADC inputs, and SPI can interface using custom wiring or a simple adaptor board, as confirmed in ST's DB2381 Rev 4 documentation.

Does EVAL-L9907 include the L9907 IC pre-mounted?

Yes - the board ships with the L9907 pre-driver IC fully assembled and soldered. It is not a bare PCB; all core logic, gate drivers, current sense amplifiers, and protection circuitry are functional out-of-box, requiring only external power, motor load, and host controller connection to operate.

Can external boost components be used instead of the onboard regulator?

Yes - jumpers J1–J4 isolate the internal boost circuit, allowing users to remove them and connect external boost components (e.g., external inductor, diode, capacitor) for customized gate drive voltage generation, as documented in Section 1.2 of DB2381 Rev 4.

What software tools are officially supported for EVAL-L9907?

ST provides free demonstration software for LabVIEW-based GUI control and SPC5Studio-integrated firmware examples. These tools support real-time parameter tuning, fault injection, current waveform capture, and closed-loop BLDC commutation - all validated against the EVAL-L9907 hardware per DB2381 Rev 4.
