Other Parts Discussed in Thread: , DRV8412, MSP430F5659
I am using DRV595 to drive a 12v/7A peltier (1.9 ohm resistance). I am using DRV595EVM circuit design.
Operating supply voltage: 12V
Input voltage : 3.3V
When no load is connected across the load terminals there is 12v across the load terminals.
When the load (peltier) is connected the voltage drops to 2V and current drawn is 0.5A.
When 2 peltier connected in series across the load the voltage is 5v and current remains the same.
Why voltage across load and current is not increasing ?
What is the issue?
Please help me.
