TPS3514 www.ti.com SLVS422C–JUNE 2002–REVISED DECEMBER 2006 PC POWER-SUPPLY SUPERVISORS FEATURES DESCRIPTION • Over-Voltage Protection and The TPS3514 is a PC switching power-supply Lockout: 12V, 5V, and 3.3V Supplies system monitor with minimum external components. It provides under-voltage lockout (UVLO), • Over-Current Protection and over-voltage (OV), under-voltage (UV), over-current Lockout: 12V, 5V, and 3.3V Supplies (OC) protection circuits, power-good indicator, and • Under-Voltage Protection and on/off control. Lockout: 12V Supplies UVLO thresholds are 4.45V (on) and 3.65V (off). • Under-Voltage Detect: 5V and 3.3V Supplies Over-current protection (OCP) and over-voltage • Fault-Protection Output with Open-Drain protection (OVP) monitor 3.3V, 5V, and 12V Output Stage supplies. When an OC or OV condition is detected, the power-good output (PGO) is asserted low and • Open-Drain, Power-Good Output Signal: the fault protection output (FPO) is latched high. Monitors Power-Good Signal Input 3.3V and PSON from low-to-high resets the latch. The OCP 5V Supplies function will be enabled 75ms after PSON goes LOW • 300ms Power-Good Delay with PGI HIGH and a debounce of typically 38ms. A • 75ms Delay: 5V, 3.3V Power-Supply built-in 2.3ms delay with 38ms debounce from PSON Short-Circuit Turn-On Protection to FPO output is enabled at turn-off. • 2.3ms PSON Control To FPO Turn-Off Delay An external resistor is connected between the RI pin and the GND pin. This will program a precise I • 38ms PSON Control Debounce (REF) for OCP function. The programmable I range is (REF) • Wide Supply Voltage Range: 4.5V to 15V from 12.5μA to 62.5μA. Three OCP comparators and the I section are supplied by VS12. The current (REF) draw from the VS12 pin is less than 1mA. The power-good feature monitors PGI, the 3.3V and 5V supplies, and issues a power-good signal when the output is ready. The TPS3514 is characterized for operation from –40°C to +85°C. The TPS3514 is available in DIP-14 and SO-14 packages.
