Texas Instruments High-Performance Analog UCC3912DPG4

The UCC3912DPG4 is a hot swap power manager with an integrated 0.15-Ω power MOSFET, designed for unidirectional current flow and circuit breaker functionality in 3-V to 8-V systems. It features programmable current limit from 0 A to 3 A with 0.25-A resolution, a fixed 3% duty cycle during fault conditions, and a maximum sourcing current of up to 4 A when IMAX is driven high. The device is housed in a 16-pin SOIC package with low thermal resistance, and includes a fault-output indicator, thermal shutdown, and 1-µA sleep mode. It supports digital programming via B0-B3 pins and a 30× fault time delay after tripping. The part meets RoHS and Green standards and operates from 0°C to 70°C.
