R2J20601NP
The PWM input is TTL level and has hysteresis. When the PWM input signal is abnormal, e.g., when the signal route
from the control IC is abnormal, the tri-state function turns off the high- and low-side MOS FETs. This function
operates when the PWM input signal stays in the input hysteresis window for 240 ns (typ.). After the tri-state mode has
been entered and GH and GL have become low, a PWM input voltage of 3.8 V or more is required to make the circuit
return to normal operation.
