EVAL-L9001 EVAL-L9001 evaluation board Data brief Device Package: PowerSSO-24 (exposed pad down) Low cost and ready to use Description EVAL-L9001 is a low cost tool designed to evaluate L9001, a smart power device designed by STMicroelectronics in advanced BCD technology. L9001 SPS (Simple Power Supply) device is a Multiple output power regulator for automotive Features applications with one buck regulator, one regulator configurable as buck or linear and one Input voltage: 5.5 V to 18 V. more linear regulator. Its output voltages are Voltage regulator for multiple power supply configurable via discrete pins. On top of the schemes: regulators, this device integrates a watchdog functional block, and a diagnosis functional block First stage asynchronous switch mode (under/over voltage, output current and regulator (VDD1) 5 V output, temperature). Second stage regulator (VDD2) supplied by VDD1 with 1.2 V output (i.e. C-core) Device is capable of low power operation mode DC LDO 5 V for ADC C supply with main regulators still active and reduced power consumption from battery. Supervision and diagnosis: VS monitoring EVAL-L9001 embeds a typical configuration for SPC5x microcontroller family supplying: Over temperature detection Output supply supervision Buck 5 V output for peripheral supply Output overcurrent protection Buck 1.2 V output for core supply Fail-safe functionality: LDO 5 V output for ADC reference supply Output under or over voltage reset generation The expansion connector allows to monitor the different diagnostic reset signal, to enable the Configurable Watchdog regulator and, if activated, to service the windows Over temperature shutdown watchdog. Low power mode Access to all relevant pins by test points Table 1.
