... The HIP408x family of devices is fabricated using a proprietary Intersil IC process which allows this family to switch at frequencies of over 500kHz. Therefore the HIP408x family is ideal for use in Voice coil motor, switching power amplifier, DC/DC converters and high performance AC/DC and step-motor control applications ...

Charge Pump Circuits There are two charge pump circuits in the HIP4080A, one for each of the two upper logic and driver circuits. Each charge pump uses a switched capacitor doubler to provide about 30µA to 50µA of gate load ...
Page 6
The peak charge pump current is only about 30µA to 50µA. The gate voltage waveform, when operating without a bootstrap capacitor, will appear similar to the dotted line shown in Figure bootstrap capacitor value approximately equal ...

... Hence the need to use a fast recovery diode. Diode recovery charge information can usually be found in most vendor data sheets. For example choose a Intersil IRF520R power MOSFET, the data book states a gate charge, Q typical and 18nC maximum, both at V maximum value of 18nC the maximum charge we should have to transfer will be less than 18nC ...

Since the internal charge pump offsets any possible diode leakage and upper drive circuit bias currents, these sources of discharge current for the bootstrap capacitor will be ignored. The bootstrap capacitance required for the example above can be calculated as ...
