Question

Power dissipation of L9960

Hi,

we are using L9960 H-Bridge -L9960 for automotive application.

Here are the inputs to consider using L9960.

Parameters	Min	Typical	Max	Remarks
Input Voltage (UBAT)	8. V	13.5 V	18. V	L9960 device will supports 4.5V > < 28V
Output Voltage (Out)	7.4 V	12.3 V	15.75 V	Output voltage almost same due to FETs switching
Input Current (IBAT)	3. mA	4. mA	5. mA	Device current consumption for normal operation
Output Load Current (ILOAD)	2. A	3. A	5. A	L9960 device will supports 1A > ILOAD < 15A

Could you please help me with power dissipation calculation of this IC. I am aware of this application note an4867-l9960-l9960t-automotive-integrated-hbridges-stmicroelectronics.pdf .

But can i get any worksheet for the same for doing power dissipation calculation?
