Description
The ZM7300 is a fully programmable digital power manager that utilizes the industry-standard I2C 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
POL converters programming, monitoring, and reporting. Parameters of the ZM7300 are programmable via the
I2C bus and can be changed by a user at any time during product development and service.
