... The ISL6594A drives the upper gate to 12V, while the lower gate can be independently driven over a range from 5V to 12V. The ISL6594B drives both upper and lower gates over a range 12V. This drive-voltage provides the flexibility necessary to optimize applications involving trade- offs between gate charge and conduction losses ...

... Connect this pin to a +12V bias supply. Place a high quality low ESR ceramic capacitor from this pin to GND PVCC This pin supplies power to both upper and lower gate drives in ISL6594B; only the lower gate drive in ISL6594A. Its operating range is +5V to 12V. Place a high quality low ESR ceramic capacitor from this pin to GND PHASE Connect this pin to the SOURCE of the upper MOSFET and the DRAIN of the lower MOSFET ...

... PDLL Operation Designed for versatility and speed, the ISL6594A and ISL6594B MOSFET drivers control both high-side and low- side N-Channel FETs of a half-bridge power train from one externally provided PWM signal. Prior to VCC exceeding its POR level, the Pre-POR overvoltage protection function is activated during initial startup ...

... Then the calculated to be 53nC for UVCC (i.e. PVCC in GATE ISL6594B, VCC in ISL6594A) = 12V. We will assume a 7 ISL6594A, ISL6594B 200mV droop in drive voltage over the PWM cycle. We find that a bootstrap capacitance of at least 0.267µF is required. FIGURE 2. BOOTSTRAP CAPACITANCE vs BOOT RIPPLE ...
