GENERAL DESCRIPTION
The ADP362x/ADP363x is a family of high current and dual high
speed drivers, capable of driving two independent N-channel
power MOSFETs. The family uses the industry-standard foot-
print but adds high speed switching performance and improved
system reliability.
The family has an internal temperature sensor and provides
two levels of overtemperature protection, an overtemperature
warning, and an overtemperature shutdown at extreme junction
temperatures.
The SD function, generated from a precise internal comparator,
provides fast system enable or shutdown. This feature allows
redundant overvoltage protection, complementing the protec-
tion inside the main controller device, or provides safe system
shutdown in the event of an overtemperature warning.
The wide input voltage range allows the driver to be compatible
with both analog and digital PWM controllers.
Digital power controllers are supplied from a low voltage
supply, and the driver is supplied from a higher voltage supply.
The ADP362x/ADP363x family adds UVLO and hysteresis
functions, allowing safe startup and shutdown of the higher
voltage supply when used with low voltage digital controllers.
The device family 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.
APPLICATIONS
AC-to-dc switch mode power supplies
DC-to-dc power supplies
Synchronous rectification
Motor drives
