Texas Instruments High-Performance Analog UCC3912PWPTR

The UCC3912PWPTR is a hot swap power manager in a TSSOP-24 package, designed for unidirectional current flow with integrated 0.15-Ω power MOSFETs. It operates from 3 V to 8 V and provides digital programmable current limiting from 0 A to 3 A in 0.25 A steps, with a maximum output current of 4 A when the IMAX pin is driven high. The device features programmable fault timing, a fixed 3% duty cycle during sustained faults, thermal shutdown at 170°C, and a fault-output indicator. It supports shutdown mode with 1 µA supply current and complies with RoHS and Green standards. The TSSOP-24 package includes exposed thermal pads for heat dissipation.
