MC33253
DYNAMIC ELECTRICAL CHARACTERISTICS VCC = 12 V, VCC2 = 12 V, CCP = 33 nF, G_EN = 4.5 V unless otherwise specified.
Typical values for TA = 25
°C, Min/Max values for TA = -40°C to +125°C, unless otherwise specified.
NOTE 2: Between 4.6V and 5.5V, the device has been a non erroneous behaviour.
NOTE 3: Input overdrive 1V
NOTE 4: Rise time is given by time needed to charge the gate from 1V to 10V (Vice versa for fall time)
NOTE : Cload corresponds to a capacitor between GATE_HS and SRC_HS for the high side and between GATE_LS and ground for low side.
N.B.
In some applications a large dV/dt at Pin 2 (C2) due to sudden changes at VCC can cause a large peak currents flowing through
Pin15 (C1).
Positive transitions at Pin2 (C2) ;mimimum peak current :
Ic1min = 2.0A
tc1min = 600ns (see for peak description)
Negative transitions at Pin2 (C2); maximum peak current :
Ic1max = 2.0A
tc1max = 600ns (see for peak description)
Current sourced by Pin 15 (C1) during a large dV/dt will result in a negative voltage at Pin 15; negative transitions at Pin2(C2);
minimum peak voltage:
Vc1min = -1.5V
tc1max = 600ns (see for peak description)
