Adaptive Gate Drive Circuit  
The driver IC design ensures minimum MOSFET dead  
time while eliminating potential shoot-through (cross-  
conduction) currents. It senses the state of the  
MOSFETs and adjusts the gate drive adaptively to  
prevent simultaneous conduction. Figure 25 provides  
the relevant timing waveforms. To prevent overlap  
during the LOW-to-HIGH switching transition (Q2 off to  
Q1 on), the adaptive circuitry monitors the voltage at the  
GL pin. When the PWM signal goes HIGH, Q2 begins to  
turn off after a propagation delay (tPD_PHGLL). Once the  
GL pin is discharged below ~1V, Q1 begins to turn on  
To prevent overlap during the HIGH-to-LOW transition  
(Q1 off to Q2 on), the adaptive circuitry monitors the  
voltage at the VSWH pin. When the PWM signal goes  
LOW, Q1 begins to turn off after a propagation delay  
(tPD_PLGHL). Once the VSWH pin falls below ~2.2V, Q2  
begins to turn on after adaptive delay tD_DEADOFF  
.
Additionally, VGS(Q1) is monitored. When VGS(Q1) is  
discharged below ~1.2V, a secondary adaptive delay is  
initiated that results in Q2 being driven on after  
tD_TIMEOUT, regardless of VSWH state. This function is  
implemented to ensure CBOOT is recharged each  
switching cycle in the event that the VSWH voltage does  
not fall below the 2.2V adaptive threshold. Secondary  
after adaptive delay tD_DEADON  
.
delay tD_TIMEOUT is longer than tD_DEADOFF
