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 programmable via the I
2
C bus and can be changed by a user at any time
during product development and deployment.
