High side and low side slope control
Register setting
Description
SLP2, SLPH1, SLPH0
%000: 1 (Minimum)
%001: 1 (Minimum)+tc.
%010: 2+tc
%011: 3
%100: 4+tc
%101: 5+tc.
%110: 6+tc.
%111: 7 (Maximum)
Gate driver strength 1 to 7.
7 is maximum current for fastest slopes.
Adjust the gate driver strength to the gate charge of the
external MOSFETs and check the desired slope.
In temperature compensated mode (tc), the MOSFET gate driver
strength is increased by one count if the overtemperature
warning temperature is reached. This compensates for
temperature dependency of high-side slope control.
