This tool downloads to your computer and offers many very nice filter selection tradeoff features. The original FilterPro tool first appeared from Burr Brown in 1991 and has been updated regularly to version 3.1.

It consumes 3.1mA operating, and a maximum of 80♚ when the enable pad is not asserted.Analog Devices is in the process of updating our website. The IC needs a 10 – 26V supply (via AUX pad). Protection features include an output transistor turn-on interlock, under-voltage lock-out, cycle-by-cycle current limit and over-temperature shut-down. “The switched GaN bootstrap transistor also avoids the traditional bootstrap diode problem of BST-to-SW capacitor over-charging due to off-state third-quadrant current flow in the low-side half-bridge GaN power transistor.” It “allows more complete charging of the BST-to-SW capacitor since the on-state GaN bootstrap transistor does not have the forward voltage drop of a traditional bootstrap diode”, according to the company. To reduce voltage drop, the bootstrap ‘diode’ is actually a third GaN transistor, switched by a control circuit. On the low-side, there is current-sense emulation which “reduces power dissipation compared to the traditional current-sense resistor and allows the low-side thermal pad to be connected to the cooling PCB power ground”, said TI. For EMI and ringing control, both high and low-side drives have an independently programmable (by resistors) choice of turn-on slew rates (low-side = 20, 50, 70 or 140V/ns.
