IS6806A
75A Smart Power Stage with Current Sensing and Thermal Monitoring
Rev1.9.1 3/2022
Innovision Semiconductor
Preliminary Datasheet
Description
The IS6806A is an integrated power stage
solution optimized for low duty cycle synchronous
buck applications. It offers high current, high
efficiency and great thermal performance with
high power density. Packaged in 5 mm x 6 mm
MLP, IS6806A enables VR design to deliver in
excess of 75 A per phase current.
The internal power MOSFETs
delivers
industry
benchmark performance in minimizing switching
and conduction losses.
The IS6806A incorporates internal MOSFET gate
driver IC that features high current driving
capability, adaptive dead-time control, and
integrated bootstrap switch, a thermal monitor that
alerts the system of excessive high junction
temperature. This driver is also compatible with
wide range of PWM controllers with the support of
both 3.3 V and 5 V PWM logic with tri-state. Diode
emulation mode can be enabled at light loads
through the use of GLCTRL signal. The device
also integrates a current monitor to provide a real
time current monitoring function (I
MON
) (scale down
version of the output inductor current). A
temperature monitor provides the system an
indication of the power stage internal temperature
(T
MON
) and can be used to throttle the system
operation down to a safer level if needed. The
device also integrates fault alerts such as HS FET
over-current, over temperature and HS MOSFET
short failures.
