DRV8962EVM: DRV8962 TEC controller

Hey Hailey,

Please try

• Half-Bridge 1 and 2 as a Low-Side Load
• Half-Bridge 3 and 4 as a High-Side Load

Then adjust the PWM Duty cycle of them on the left side - try setting HB1 and 2 to 100%, with 3 and 4 to 0%,  or the inverse of that setup.  You can also test it with a brushed DC motor connected between the outputs first to more easily verify if the setup is working.

Best,

Jacob

Hi Hailey,

I assume you removed the jumper shorts on IN2 and IN4 from the MCU to the driver. You should also remove EN2 and EN4 jumpers and then short EN1 & EN2 as well as EN3 & EN4.

HI，Murugavel：

thanks for you reply！

i have short mcu to in1 and in2，mcu to in3 and in4，and also control in1 and in3 input as you said，my tec resistor is 2ou，but couldnt get 10A，test result as followpink is current，as show it only 3A，vref is 3.3v，and has unexpected negetive current

• i want to know does it also need tue isence together？

Hi Hailey,

Yes you must tie the corresponding IPROPIx together as well.
