Texas Instruments  UCD7100PWP

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. 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 25-ns 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.

For fast switching speeds, the UCD7100 output stage uses the TrueDrive™ output architecture, which delivers rated current of ±4 A into the gate of a MOSFET during the Miller plateau region of the switching transition. It also includes a 3.3-V, 10-mA linear regulator to provide power to the digital controller.

The UCD7000 driver family is compatible with standard 3.3-V I/O ports of DSPs, Microcontrollers, or ASICs. UCD7100 is offered in aPowerPAD™ HTSSOP-14.
