Texas Instruments UCD7100 Low-Side MOSFET Driver
Texas Instruments UCD7100 Low-Side MOSFET Driver is a digital control compatible driver for applications that use digital control technology that requires 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. The Texas Instruments UCD7100 provides a cycle-by-cycle current limit function with a programmable threshold and a digital output current limit flag that the host controller can monitor. 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 does not respond to a failure situation in time.Features
