Overview
The ADP3654ARHZ-R7, produced by Analog Devices Inc., is a high current and dual high-speed driver designed to drive two independent N-channel power MOSFETs. This driver is notable for its industry-standard footprint and enhanced high-speed switching performance. It supports a wide input voltage range from 4.5 V to 18 V, making it compatible with both analog and digital PWM controllers. The ADP3654 features precise undervoltage lockout (UVLO) with hysteresis, ensuring safe startup and shutdown of the higher voltage supply when used with low voltage digital controllers.
