Texas Instruments High-Performance Analog UCC3912DPTR

The UCC3912DPTR is a hot swap power manager with an integrated 0.15-Ω power MOSFET for unidirectional current control in 3-V to 8-V systems. It features programmable current limits from 0 A to 3 A in 0.25-A steps, a maximum output current of 4 A when IMAX is high, and a fixed 3% duty cycle to limit power during faults. The device includes a fault-output indicator, thermal shutdown, and 1-µA sleep mode current. It is packaged in a 16-pin SOIC (D) with thermal exposure pads designed for heat dissipation and operates over a temperature range of 0°C to 70°C. All control functions are integrated, requiring only an external fault timing capacitor for operation.
