9.1 Overview

The UCD7100 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 UCD7100 is a low-side ±4-A high-current MOSFET gate driver. The UCD7100 allows digital power controllers such as the UCD9110 or UCD9501 to interface to the power stage in single-ended topologies. It provides a cycle-by-cycle current limit function with programmable threshold and a digital output current limit flag, which can be monitored by the host controller. With a fast 25-ns cycle-by-cycle current limit protection, the driver can turn off the power stage in the unlikely event that the digital system cannot respond to a failure situation in time.
