详情介绍:

The MD18624B high-frequency gate driver is designed to drive both low-side N-Channel MOSFETs with maximum control flexibility of independent inputs. Each channel can source and sink 3A peak current along with rail-to-rail output capability. Less than 20ns rise and fall time with 2.2nF load decrease the switching loss of MOSFET. MD18624B has 11ns rising and falling propagation delay which allows the systems operating at high frequency with less delay matching variations. These delays are very suited for applications requiring dual-gate drivers with critical timing, such as synchronous rectifiers. When connecting two channels in parallel to increase current-drive capability, intelligent stack detection circuit is implemented to add extra 5ns dead-time between the two channels to avoid shoot through current without adding external series resistor. The inputs can handle -10V to 26V PWM, which increases robustness against ringing from gate transformer and/or parasitic inductance of long routing traces. The input PINs thresholds are fixed and independent of the VDD supply voltage. The MD18624B is offered in SOP-8 package.
