(see maximum ratings table on page 3). 4. after approx. 2ms the fault is reset. (see dynamic characteristics table on page 5). 5. pwm generator must be disabled within fault duration to guarantee shutdown of the system, overcurrent condition must be cleared before resuming operation. 29 1 3- phase ac motor boot -strap capacitors w v u vdd (28) itrip (16) vss (29) 100nf controller v+ dc bus capacitors phase leg current sense vth (27) enable 10m current sensing can use a single sense resistor or phase leg sensing as shown 0.1m 15 v flt /en (18) iram 256-1567a v + (13) vru (17) vrv (19) vrw (21) hin2 (22) hin1 (20) hin3 (23) lin 1 (24) lin 2 (25) lin 3 (26) vb3 (1) vb2 (5) vb1 (9) w, vs3 (2) v, vs2 (6) u, vs1 (10) 5 v
