I would like to use a VNH3SP30-E to control the rotation of a dc motor. No PWM. My question is about the inputs, INA, INB, ENA and ENB. Do I need pullup and/or series resistors for these inputs? Can I just tie the ENA and ENB to +5V? The inputs INA and INB will be either +5V or gnd.

Dear Customer,

We recommend to insert the pull-up/series resistors as stated in the application schematic inserted in the datasheet (fig.33):

-

ENx: 3.3K for Pull-up resistor;

-

INx: 1K as series resistor;

We are available for any further information you may need.

Best Regards,
