Description
The ZM7300 is a fully programmable digital power manager that utilizes the industry-standard I
2
C
communication 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
TM
POL converters
and other industry standard power and peripheral devices.
Parameters of the ZM7300 are
2
programmable via the I C bus and can be changed by a user at any time during product development
and deployment.
