SLVSCP6H July 2014 – June 2020 DRV10983
The DRV10983 has 16 options for PWM dead time which can be used to configure the time between one of the bridge FETs turning off and the complementary FET turning on. Deadtime[3:0] can be used to configure dead times between 40 ns and 640 ns. Take care that the dead time is long enough to prevent the bridge FETs from shooting through. The recommend minimum dead time is 440 ns for 24-V VCC and 360 ns for 12-V VCC.
The DRV10983 offers two options for PWM switching frequency. When the configuration bit DoubleFreq is set to 0, the output PWM frequency will be 25 kHz and when DoubleFreq is set to 1, the output PWM frequency will be 50 kHz. It is recommended to operate the device in 25 kHz PWM switching frequency if there is an error in the estimated Kt around 30% duty cycle in 50 kHz PWM switching frequency.
