STMicroelectronics EVAL-L9001 Evaluation Board

STMicroelectronics EVAL-L9001 Evaluation Board for L9001 is used to evaluate the STMicroelectronics L9001 smart power device in advanced BCD technology. The L9001 is a multiple output power regulator for automotive applications with one buck regulator, one regulator configurable as buck or linear, and one more linear regulator. Its output voltages are configurable via discrete pins. EVAL-L9001 embeds a typical configuration for the SPC5x family, supplying buck 5V output for peripheral supply, buck 1.2V output for core supply, and LDO 5V output for ADC reference supply. The expansion connector allows for monitoring the different diagnostic reset signals to enable the regulator and, if activated, to service the Windows watchdog.
