ASL1507SHNY - Single Phase boost Converter IC, automotive grade, SPI, limping home mode.
summarize
The ASL1507SHN is a single-phase boost converter IC with limping home mode. It provides an SPI interface for extensive control and diagnostic communication with external microcontrollers and integrates a customer-programmable limping home mode. When the SPI communication with the microcontroller fails, the driver IC allows configurable operations in emergency mode. Once a loss of SPI communication is detected, the limping home mode is activated.
