Description

General part information

TPS3513 Series

The TPS3513 is designed to optimize PC switching power supply system with minimum external components. It provides undervoltage lockout (UVLO), protection circuits, power good indicator, and on/off control.

UVLO thresholds are 4.45 V (on) and 3.65 V (off). Overcurrent protection (OCP) and overvoltage protection (OVP) monitor 3.3 V, 5 V, and 12 V. 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 75 ms afterPSONgoes low, and a debounce of typically 38 ms. A built-in 2.3-ms delay with 38-ms debounce fromPSONtoFPOoutput is enabled at turnoff.

An external resistor is connected between the RI pin and the GND pin. This will introduce an accurate I(ref)for OCP function. The I(ref)range is from 12.5 µA to 62.5 µA. The formula for choosing RI resistor is V(RI)/I(ref). Three OCP comparators and the I(ref)section are supplied by VS12. The current draw from the VS12 pin is less than 1 mA.
