ADP3654ARDZ-RL Analog Devices

High Speed, Dual, 4 A MOSFET Driver Data Sheet ADP3654 FEATURES GENERAL DESCRIPTION Industry-standard-compatible pinout The ADP3654 high current and dual high speed driver is capable High current drive capability of driving two independent N-channel power MOSFETs. The Precise UVLO comparator with hysteresis driver uses the industry-standard footprint but adds high speed 3.3 V-compatible inputs switching performance. 10 ns typical rise time and fall time at 2.2 nF load The wide input voltage range allows the driver to be compatible Matched propagation delays between channels with both analog and digital PWM controllers. Fast propagation delay Digital power controllers are powered from a low voltage 4.5 V to 18 V supply voltage supply, and the driver is powered from a higher voltage supply. Parallelable dual outputs The ADP3654 driver adds UVLO and hysteresis functions, Rated from 40C to +125C junction temperature allowing safe startup and shutdown of the higher voltage supply Thermally enhanced packages, 8-lead SOIC N EP and 8-lead when used with low voltage digital controllers. MINI SO EP The driver is available in thermally enhanced SOIC N EP and APPLICATIONS MINI SO EP packaging to maximize high frequency and AC-to-dc switch mode power supplies current switching in a small printed circuit board (PCB) area. DC-to-dc power supplies Synchronous rectification Motor drives FUNCTIONAL BLOCK DIAGRAM NC 1 8 NC ADP3654 V DD INA 2 7 OUTA 3 PGND 6 UVLO VDD 4 INB 5 OUTB Figure 1. Rev.
