MD18624-Q1 5-A Peak, High Frequency, Dual Low-Side Driver
The MD18624-Q1 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 5A peak current along with rail-to-rail output capability. Lessthan 10nsrise and fall time with 2.2nF load decrease the switching loss of MOSFET. MD18624-Q1 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 20V PWM, which increases robustness against ringing from gate trans
