7.3.4 Output Stage

The DRV5033 output stage uses an open-drain NMOS, and it is rated to sink up to 30 mA of current. For proper

operation, calculate the value of the pullup resistor R1 using Equation 1.

(1)

The size of R1 is a tradeoff between the OUT rise time and the current when OUT is pulled low. A lower current

is generally better, however faster transitions and bandwidth require a smaller resistor for faster switching.

In addition, ensure that the value of R1 > 500

Ω to ensure the output driver can pull the OUT pin close to GND.

NOTE

Vref is not restricted to VCC. The allowable voltage range of this pin is specified in the

Absolute Maximum Ratings.
