The UCD7100PWP is a single low-side MOSFET Driver with current sense. 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 ±4A high-current MOSFET gate driver. It allows the digital power controllers such as 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 25ns cycle-by-cycle current limit protection, the driver can turn-OFF the power stage in the unlikely event that the digital system can not respond to a failure situation in time.
