ASL2500SHN数据手册恩XP中文资料规格书

描述 Description

The ASL2500SHN is a highly integrated and flexible two-phase DC-to-DC boost converter IC that has an SPI interface allowing control & diagnostic communication with an external MCU. It is a two-phase converter which can have two independent outputs. The flexible driver can be configured, via the SPI interface, as a single output converter, or with multiple combinations of number of outputs and phases. Read more on the ASL2500SHN Data Sheet.

The ASL2507SHN is a dual phase boost converter IC with a Limp Home mode feature. It provides an SPI interface for extensive control and diagnostic communication with an external MCU and integrates a customer programmable Limp Home mode. The driver IC allows configurable operation during the Limp Home mode in case SPI communication with the MCU has failed. Once the loss of SPI communication is detected, the Limp Home mode gets activated. Read more on the ASL2507SHN Data Sheet.
