Texas Instruments TPS3514DR The TPS3514 is a PC switching power-supply system monitor with minimum external components. It provides under-voltage lockout (UVLO), over-voltage (OV), under-voltage (UV), over-current (OC) protection circuits, power-good indicator, and on/off control. UVLO thresholds are 4.45V (on) and 3.65V (off). Over-current protection (OCP) and over-voltage protection (OVP) monitor 3.3V, 5V, and 12V supplies. When an OC or OV condition is detected, the power-good output (PGO) is asserted low and the fault protection output (FPO) is latched high.PSONfrom low-to-high resets the latch. The OCP function will be enabled 75ms afterPSONgoes LOW with PGI HIGH and a debounce of typically 38ms. A built-in 2.3ms delay with 38ms debounce fromPSONtoFPOoutput is enabled at turn-off. An external resistor is connected between the RI pin and the GND pin. This will program a precise I(REF)for OCP function. The programmable I(REF)range is from 12.5µA to 62.5µA. Three OCP comparators and the I(REF)section are supplied by VS12. The current 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.

General part information

TPS3514 Series

The TPS3514 is a PC switching power-supply system monitor with minimum external components. It provides under-voltage lockout (UVLO), over-voltage (OV), under-voltage (UV), over-current (OC) protection circuits, power-good indicator, and on/off control.

UVLO thresholds are 4.45V (on) and 3.65V (off). Over-current protection (OCP) and over-voltage protection (OVP) monitor 3.3V, 5V, and 12V supplies. When an OC or OV condition is detected, the power-good output (PGO) is asserted low and the fault protection output (FPO) is latched high.PSONfrom low-to-high resets the latch. The OCP function will be enabled 75ms afterPSONgoes LOW with PGI HIGH and a debounce of typically 38ms. A built-in 2.3ms delay with 38ms debounce fromPSONtoFPOoutput is enabled at turn-off.

An external resistor is connected between the RI pin and the GND pin. This will program a precise I(REF)for OCP function. The programmable I(REF)range is from 12.5µA to 62.5µA. Three OCP comparators and the I(REF)section are supplied by VS12. The current draw from the VS12 pin is less than 1mA.
