TIMING DIAGRAM

1. Input Interlock Timing Diagram

When the input signals (HIN/LIN) are high at the same time, the output (HOUT/LOUT) will maintain previous status. But if the input signals

(HIN/LIN) go high simultaneously, HIN signals would be active and cause HOUT to enter into high status.

HIN

NOTE 1: Input pulse width should be set to more than

200ns for HIN/LIN input filter circuit.

NOTE 2: If high-high status of input signals HIN/LIN

LIN

completes with one input signal in low level and the

other in high level, the output will enter into high-low

status without dead time.

HOUT

NOTE 3: This diagram does not show delay time

between input and output.

NO

DEAD-TIME

The M81019FP matches delay between the low side and high side driver allowing minimized dead time control for better speed range and

torque control in motor drive applications.

3. Short Circuit Protection Timing Diagram

When overcurrent is detected, CIN will be tripped if LIN is high; then the short circuit protection will activate and shut down the outputs

and FO will indicate fault by going low. As soon as FO_RST is driven high, short circuit protection will deactivate and FO goes high.

The output will then respond to any subsequent active input signal.

than 400ns for FO_RST input filter circuit.
