Hello,
I'm building a circuit to control a solenoid. I'm almost done, but the one issue I'm having is calculating the power dissipation. The datasheet states that the power dissipation is the product of the output current times voltage across the conducting output transistor times duty cycle.
My circuit is pretty similar to the one in figure 13 of the data sheet from the DRV101.
My duty cycle is set for 48% and delay is 100ms.
So is the voltage across the the output transistor the saturation voltage they are talking about? if so how do I measure this to calculate power dissipation?
Any advice will be appreciated.
