Adjustable Ramp Rate vs. ON Pin Current (5.5 V, 25 °C)

Adjustable Slew Rate (ON Pin 2)

SLG5NT1547V has a built in configurable slew control feature. The configurable slew control uses current detection method on

Pin 2. When ON voltage rise above ON_VIH_INI (1.2 V typical), the slew control circuit will measure the current flowing into Pin

2. Based on the current flowing into pin 2, different slew rates will be selected by the internal control circuit. See I_ON vs. Tslew

table on page 2. The slew rate is configurable by selecting a different R1 resistor value as shown on application diagram on page

2. Calculating the R1 value depends on both the desired slew rate, and the VOH level of the device driving the ON Pin 2.

ON_Current = (GPIO_VOH – ON_VREF (1.05 V typical)) / R1
