4.1.3.  High-Side Output Installation Connections 

When connecting high-side outputs, note that 

 

High-side outputs are connected to one of two internal bus bars, which can be 
connected to a +12 V or +24 V battery. Each busbar powers 4x 10A outputs. 
Maximum load on each busbar is 40A. 

 

High-side outputs can provide switched battery power to a variety of load 
types in a vehicle.  

If large inductive loads are used and the high-side output is providing a 
continuous PWM signal, the PWM peak current must not be greater than the 
specified continuous current for the output (in continuous mode, the average 
current flow through the diode at 50% duty cycle is approximately equal to ½ the 
peak current). 

When connecting high-side outputs, follow these best practices: 

 

Do not connect high-side outputs to loads that will draw currents greater than 
the maximum peak current or maximum continuous current. 

 

Connect the load grounds in close physical proximity to the VMM1210 power 
grounds.
