8.3.3 Adjustable Slew Rate

A resistor to GND on the RT pin sets the slew rate, and the higher the resistor the lower the slew rate. Rise times are shown below.

Table 8-2 Rise Time vs RT vs VIN

RT Resistor

VIN = 5 VVIN = 3.3 VVIN = 1.8 VVIN = 1.2 VVIN = 0.8 V

The following equation can be used to estimate the rise time for different VIN and RT resistors:

tR = (0.0246 VIN + 0.0308) × RT + 3.3219 VIN + 6.7312

where

  • tR = Rise time in µs.
  • VIN = Input voltage in V.
  • RT = RT Resistor in Ω.
