EVAL-L9945 STMicroelectronics

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 The board can be connected to the SPC563M- Voltage min/max: 3.8 V to 36 V. DISP, the Discovery+ board developed for the 8-channel configurable MOSFET pre-driver: SPC563M64L. High-side (N-channel and P-channel MOS) Table 1. Device summary Low-side (N-channel MOS) H-bridge (up to 2 H-bridge) Order Code Reference Peak & Hold (2 loads) EVAL-L9945 EVAL-L9945 evaluation board 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.
