DESCRIPTION
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.
PSON from low-to-high resets the latch. The OCP
function will be enabled 75ms after PSON goes LOW
with PGI HIGH and a debounce of typically 38ms. A
built-in 2.3ms delay with 38ms debounce from PSON
to FPO output 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 12.5mA to 62.5mA. 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. The TPS3514 is available in DIP-14
and SO-14 packages.
