EVAL-L9945

EVAL-L9945 EVAL-L9945 evaluation board Data brief Description 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. 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. The board can be connected to the SPC563MDISP, the Discovery+ board developed for the SPC563M64L. Table 1.
