DESCRIPTION

DIP-8

The UTC 3511 is designed to provide the voltage, and current

supervisor function, power good output (PGO), fault protection

latch (FPL_N), and protection detector function (PDON_N) control

for switching power systems.

For supervisor function, it provides the over voltage detector

(OVD) monitoring for 3.3V, 5V, 12V; the under voltage detector

(UVD) monitoring for 3.3V, 5V. When 3.3V or 5V voltage is

decreasing to 2.69V, 4.3V respectively, the under voltage

detector (UVD) function will be enabled to reset the PGO signal

from high to low,and the FPL_N is latched HIGH. When 3.3V, 5V

or 12V voltage is increasing to 3.9V, 6.1V or 13.4V respectively,

the over voltage detector (OVD) function will be enabled to reset

the PGO signal from high to low, and the FPL_N is latched HIGH.

To achieve better immunity for lighting surge glitch and to

prevent accidental power shut down during dynamic loading

condition, the de-bounce time for UVD and OVD is 73us. The

power supply is turned on after 38mS de-bounce time when

FPL_N signal is set from high to low.
