DLPS240A June 2024 – August 2024 DLPA3085
PRODUCTION DATA
The DLPA3085 has two shutdown modes: a normal shutdown initiated after pulling PROJ_ON level low and a fast power-down mode. The fast power down feature can be enabled or disabled through register Main Status register (0x01), bit 7, FAST_SHUTDOWN_EN. By default, the mode is enabled.
When the fast power-down feature is enabled, a fast shutdown is initiated for specific faults. This shutdown happens autonomously from the DLPC. The DLPA3085 enters the fast-shutdown mode only for specific faults, thus not for all the faults flagged by the DLPA3085. The faults for which the DLPA3085 goes into fast shutdown are listed in Table 6-7.
