SLVSCC0D November 2013 – October 2019 DRV8850
The rise and fall times (tR and tF) of the outputs can be adjusted by the value of an external resistor connected from the SR pin to ground. The output slew rate is adjusted internally by the DRV8850 device by controlling the ramp rate of the driven FET gate.
The typical voltage on the SR pin is 0.6 V driven internally. Changing the resistor value monotonically increases the slew rates from approximately 100 ns to 100 µs. Recommended values for the external resistor are from GND to 2.4 MΩ. If the SR pin is grounded then the slew rate is 100 ns.
