R2J20652ANP
The PWM input is TTL level and has hysteresis. When the signal route from the control IC is high impedance, 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 100 ns (typ.). After the tri-state mode has been entered and GH and GL have become
low, a PWM input voltage of 3.4 V or more is required to make the circuit return to normal operation.
