产品概述
The UCD7201 is a member of the UCD7K family of
digital control compatible drivers for applications utilizing digital control techniques or applications
requiring fast local peak current limit protection.The UCD7201 includes dual low-side ±4-A high-
current MOSFET gate drivers. It allows the digital
power controllers such as UCD9110 or UCD9501 to
interface to the power stage in double ended
topologies. It provides a cycle-by-cycle current limit function for both driver channels, a programmable
threshold and a digital output current limit flag which
can be monitored by the host controller. With a fast
cycle-by-cycle current limit protection, the driver can turn off the power stage in the event of an
overcurrent condition.
