GENERAL DESCRIPTION
The ADP3654 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 ADP3654 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.
