Description
The ZM7300 is a fully programmable digital power manager that utilizes the industry-standard I
bus interface to control, manage, program and monitor up to 32 Z-series POL converters and 4 independent
power devices. The ZM7300 completely eliminates the need for external components for power management and
programming and monitoring of the Z-One
devices. Parameters of the ZM7300 are programmable via the I
during product development and deployment.

... Z-series POL converters protect outputs by triggering either a fault or an error depending on the severity of the problem (see POL converter datasheets). Fault propagation between POL converters belonging to the same group is a programmable function of POL converters. The DPM allows propagating faults and errors between groups of POL converters and, in case of an error DC/DC front-end and an optional crowbar. propagation delay for fault/error propagations is less than 10µ ...
