Device State
1) Previous current sense assignment to be reset by IN1=IN2=low and both high side switches off (see
2) When both high side switches are in on state, the CS provides the sense signal for the high side switch, which has been
3) In short circuit of HSS or LSS, the junction temperature will arise and as soon as the over temperature shut down threshold
