1. DESCRIPTION

The ADP3654ARHZ-R7 high current and dual high speed driver is capable of driving two independent N-channel power MOSFETs. The driver uses the industry-standard footprint but adds high speed switching performance. The wide input voltage range allows the driver to be compatible with both analog and digital PWM controllers. Digital power controllers are powered from a low voltage supply, and the driver is powered from a higher voltage supply. The ADP3654ARHZ-R7 driver adds UVLO and hysteresis functions, allowing safe startup and shutdown of the higher voltage supply when used with low voltage digital controllers. The driver is available in thermally enhanced SOIC_N_EP and MINI_SO_EP packaging to maximize high frequency and current switching in a small printed circuit board (PCB) area.
