Digital Control Compatible Dual Low-Side ±4 Amp MOSFET Drivers with Programmable
Common Current Sense
The
high-current MOSFET gate drivers. It allows the
digital
power
controllers
UCD9501 to interface to the power stage in double
ended topologies. It provides a cycle-by-cycle current
limit
function
for
both
programmable threshold and a digital output current
limit flag which can be monitored by the host control-
ler. With a fast cycle-by-cycle current limit protection,
the driver can turn off the power stage in the event of
an overcurrent condition.
UCD7201

For fast switching speeds, the UCD7201 output
stages use the TrueDrive output architecture, which
delivers rated current of ±4 A into the gate of a
MOSFET during the Miller plateau region of the
switching transition. It also includes a 3.3-V, 10-mA
linear regulator to provide power to the digital control-
ler.
