description (continued)
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. PSON from low-to-high resets the latch.
The OCP function will be enabled 75 ms after PSON goes low, and a debounce of typically 38 ms. A built-in
2.3-ms delay with 38-ms debounce from PSON to FPO output 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
μ
A to 62.5
μ
A. 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.
The power good feature monitors PGI, 3.3 V and 5 V, and issues a power good signal when the output is ready.
The TPS3513 is characterized for operation from –40
°
C to 85
°
C.
