  • The EVAL- L9945 is an evaluation board designed to evaluate L9945, a smart power device designed by STMicroelectronics in advanced BCD technology.

    L9945 is a flexible high-side/ low-side configurable pre-driver able to drive both NMOS and PMOS. It is possible to configure the device as independent 8 high-side and low-side pre-driver or as 2 H-Bridge pre-driver or 2 pick and hold pre-driver by using SPI configuration and jumper on the board.
    All channels are protected against short circuit, over current and over-temperature conditions.
    The board can be connected to the SPC563M-DISP, the Discovery+ board developed for the SPC563M64L.

    Key Features

    • Voltage min/max: 3.8 V to 36 V.
    • 8-channel configurable MOSFET pre-driver:
      • High-side (N-channel and P-channel MOS)
      • Low-side (N-channel MOS)
      • H-bridge (up to 2 H-bridge)
      • Peak & Hold (2 loads)
    • Device registers setting and the full diagnostic are available through SPI.
    • Access to all relevant pins by test points.
    • Input signal connector compatible with the SPC563M-DISP (SPC563M64L Discovery+ evaluation board).
    • Possibility to connect a generic microcontroller board by using a simple adapter.
