UCD7100
SLUS651D –MARCH 2005–REVISED OCTOBER 2014
UCD7100 Digital Control Compatible Single Low-Side ±4-A MOSFET Driver with Current
Sense
1 Features 3 Description
The UCD7100 is a member of the UCD7K family of
1
• 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 provides a cycle-by-cycle current limit
• 25-ns Current Sense to Output Delay
function with programmable threshold and a digital
• Programmable Current Limit Threshold
output current limit flag which can be monitored by
the host controller. With a fast 25-ns cycle-by-cycle
• Digital Output Current Limit Flag
current limit protection, the driver can turn off the

system can not respond to a failure situation in time.
• Lead(Pb)-Free Packaging
