The VMM2404 is powered by the vehicle battery. The VMM2404 operates in a
12 V or 24 V system, and can operate from 6 V up to 32 V, with over-voltage
protection at 36 V.
The various pins on the connectors are used for different types of power, as
detailed in the following sections.
5.1. Logic and output power
The VMM2404 has 3 pins, labeled VBATT, dedicated to providing power for
logic and outputs, and 4 pins, labeled GND, dedicated to grounding the
VMM2404.
Note: The power and ground connections are usually paralleled over several
pins to minimize voltage drops on higher current applications.
5.1.1. Logic and Output Power Capabilities
Logic power provides power to the logic circuit, which consists of the
microprocessor, RAM, etc. The logic circuit can draw a maximum of 300 mA.
Output power provides power to the output circuits through a battery or ground
connection. Each output circuit can draw a maximum of 3 A.
