A floating high-side driver is said to enable bootstrap operation up to 600V, allowing these devices to be used on the high-voltage rails found in motor drives and power supplies. A high peak-current drive capability ensures the MOSFET or IGBT can switch quickly, delivering greater efficiency under high frequency operation. Inputs that are logic-compatible down to 3.3V are said to further simplify the interface between the controller and the power switches.
To protect the MOSFET/IGBT from shoot-through, all devices have matched delays and the half-bridge drivers feature a pre-set internal dead time. Additional self-protection features include Schmitt inputs to avoid false triggering, a gate drive that is tolerant to negative transients arising from high dV/dt switching, and under-voltage lockout to avoid malfunction under low supply voltage conditions.
The DGD21xx series is supplied in SO-8 and SO-16 packages, providing pin-compatibility with other sources.
