UCD7100 Digital Control Compatible Single Low-Side ±4-A MOSFET Driver with Current
Sense Features 3 DescriptionThe UCD7100isa memberof the UCD7K familyof Adjustable Current Limit Protection digital control compatible drivers for applications• 3.3-V, 10-mA Internal Regulator utilizing digital control techniques or applications• DSP/µC Compatible Inputs requiring fast local peak current limit protection. Single ±4-A TrueDrive™ High Current Driver The UCD7100 is a low-side ±4-A high-current 10-ns Typical Rise and Fall Times with 2.2-nF MOSFET gate driver.It allows the digital power
Loads controllers such as UCD9110 or UCD9501 to
interface to the power stage in single ended• 25-ns Input-to-Output Propagation Delay topologies.It providesa cycle-by-cycle current limit• 25-ns Current Senseto Output Delay function with programmable threshold anda digital• Programmable Current Limit Threshold output current limit flag which can be monitored by
the host controller. Witha fast 25-ns cycle-by-cycle• Digital Output Current Limit Flag current limit protection, the driver can turn off the• 4.5-Vto 15-V Supply Voltage Range power stagein the unlikely event that the digital• Rated from -40°Cto 105°C system can not respondtoa failure situationin time.
