STMicroelectronics EVAL-L9907-H

Overview

EVAL-L9907-H from STMicroelectronics is an evaluation board designed to validate the L9907 3-phase BLDC pre-driver IC in real motor control systems. It supports 6–54 V battery supply, delivers up to 120 A load current, enables full SPI-based device control and diagnostics, and integrates configurable shunt sensing (Phase U+V or Phase U+Total), LED status indicators, and direct SPC56 Discovery board compatibility.

For engineers reviewing the EVAL-L9907-H datasheet, EVAL-L9907-H pinout, EVAL-L9907-H application, or EVAL-L9907-H equivalent, this board provides verified hardware access to all L9907 signals-including six PWM inputs, two enable lines, two ADC inputs for current sensing, SPI interface, and external boost configuration-enabling rapid validation of gate drive strategies, fault handling, and current-sense amplifier programmability in 48 V automotive and industrial BLDC systems.

Technical Context

The EVAL-L9907-H implements a complete test platform for the L9907 pre-driver, which features independent control of six high- and low-side gate drivers, four selectable gate current levels (100/250/500/1000 mA), integrated boost regulator (operable down to 6 V input), dual programmable current sense amplifiers (gain and offset configurable via SPI), and protection against shoot-through, overtemperature, and short-circuit faults.

Hardware design includes modular PCB sections for swapping SMD or through-hole power MOSFETs, test-point access to all critical nodes (VBatt, Vcc, EN1/EN2, PWMx, CSx, SPI lines), jumper-selectable external boost components, and USB-SPI adapter support-enabling flexible integration with SPC560P-DISP or custom microcontroller platforms running LabVIEW GUI or SPC5Studio firmware.

FAQ

Does EVAL-L9907-H require external power supplies beyond VBatt?

No. The board derives Vcc (5 V or 3.3 V) from the host MCU board (e.g., SPC560P-DISP) and uses its integrated boost regulator to generate gate drive voltages from the 6–54 V VBatt input. No auxiliary power rails are needed for basic operation.

Can EVAL-L9907-H be used with non-SPC5 microcontrollers?

Yes. While optimized for SPC56 Discovery boards, it accepts standard SPI, PWM, EN, and ADC signals. Users can interface with any MCU supporting six PWM outputs, two digital enables, two ADC inputs, and SPI-using wire connections or a custom adaptor per the board's pin-accessible test points.

What protection features of the L9907 IC are observable on this board?

All L9907 protections-including shoot-through prevention, overtemperature shutdown, and short-circuit detection on each output channel-are implemented and testable. Fault conditions trigger diagnostic registers readable via SPI and may assert hardware flags visible at test points or reflected in LED behavior during failure simulation.

Is demonstration software included with the EVAL-L9907-H purchase?

No physical media is shipped. ST provides free downloadable demonstration software-including LabVIEW GUI and SPC5Studio-compatible firmware-from www.st.com. The software supports real-time motor control, current sensing calibration, register monitoring, and fault injection testing directly through the board's SPI interface.
