Recommended Operating Conditions

TJ = 25°C (unless otherwise noted)
PARAMETERCONDITIONSMINMAXUNIT
VGS Gate drive voltage 4.5 16 V
VIN Input supply voltage(1) 36 V
ƒSW Switching frequency CBST = 0.1 µF (min) 5 50 kHz
IOUT RMS motor winding current 50 A
TJ Operating temperature 125 °C
Up to 32-V input use one capacitor per phase, MLCC 10 nF, 100 V, X7S, 0402, PN: C1005X7S2A103K050BB from VIN to GND return. Between 32-V to 36-V input operation, add RC switch-node snubber as described in the Electrical Performance section of this data sheet.
