mitsubishi semiconductors high voltage half bridge driver M81734FP 4 may. 2010 function timing diagram 1. ho has positive logic with reference to in . lo has negative logic with reference to in. 2. output signal (ho) is trigger ed by the edge of input signal. 3. logic during uv(v cc , v bs ) error error signal ho lo uv error (v cc ) ho is locked at ?l? level as long as uv error for v cc is detected. after v cc uv reset level, the lock for ho is removed following an ?l? state of the in signal, and then ho responds to the input. (v cc >v bs ) lo is locked at ?l? level as long as uv error for v cc is detected. after v cc exceeds v cc uv reset level, the lock for lo is removed and responds to in signal. uv error (v bs ) ho is locked at ?l? level as long as uv error for v bs is detected. after v bs uv reset level, the lock for ho is removed following an ?l? state of the in signal, and then ho responds to the input. lo is independent of v bs to respond to in. *if uv error for v cc is detected when ho is in ?h? level and the falling speed of v cc is exceeds 0.03v/ s, the off signal for ho might not be transmitted from low side to high side and then ho stays ?h?. *if supply voltage drops lower than vponr, output becomes ?l? not after tvccuv or tvbsuv but after tponr(fil).
mitsubishi semiconductors high voltage half bridge driver M81734FP 5 may. 2010 4. supply start up sequence please start up v cc supply and v bs supply in that order, and, please shut down v bs supply and v cc supply in that order. please start up v cc supply and v bs supply with gentle slope. if you start up supply with sharp slope, there is some possibility that ho or lo outputs ?h? for a moment. if v cc supply is less than 10v(outside of re commended operating conditions), t here is some possibility that output does not change in response to input. please evaluate care fully about supply start up or restart after shut down in your application systems. package outline
