2 / 16 page UCC2912 UCC3912 PROGRAMMABLE HOT SWAP POWER MANAGER SLUS241D − MARCH 1994 - REVISED NOVEMBER 2003 2 www.ti.com description (continued) The UCC3912 family is designed for unidirectional current flow, emulating an ideal diode in series with the power switch. This feature is particularly attractive in applications where many devices are powering a common bus, such as with SCSI Termpwr. The UCC3912 family can be put into sleep mode drawing only 1- µA of supply current. The SHTDWN pin has a preset threshold hysteresis which allows the user the ability to set a time delay upon startup to achieve sequencing of power. Other features include an open drain FAULT output indicator, thermal shutdown, under voltage lockout, and a low thermal resistance small outline package. absolute maximum ratings over operating free-air temperature (unless otherwise noted)†} VIN 8 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. ‡ Currents are positive into, negative out of the specified terminal. Consult Packaging Section of the Interface Products Data book (TI Literature Number SLUD002) for thermal limitations and considerations of packages. package information DIL-16, SOIC-16 N, DP Package (TOP VIEW) TSSOP-24, PWP Package (TOP VIEW) *Pin 5 serves as lowest impedance to the electrical ground; Pins 4, 12, and 13 serve as heat sink/ground. These pins should be connected to large etch areas to help dissipate heat. For N package, pins 4, 12, and 13 are N/C. *Pin 9 serves as lowest impedance to the electrical ground; other GND pins serve as heat sink/ground. These pins should be connected to large etch areas to help dissipate heat.
