(CRT= 22pF)
Notes:
1.
Nominal values are: VS = 2.5V, VH = 2.9V and VL = 2.1V.
2.
By adding an external capacitor between the CRT pin and ground, slew rate at VDRV output can be controlled. The controlling equation is tf or tr = 2us +
(0.123us/pF * CRT). CRT is nominally 22pF, yielding tf = tr =4.7us. The constant comes from an internal capacitor. The hot side of the capacitor and the CRT pin
should have a guard pattern around them to avoid unnecessary interference.
