Pin Descriptions

GND

Function

GROUND

/RESET

/RESET remains LOW while V_CCis below

V_TH, and for at least 140ms after V_CCrises

above V_TH

V_CC

Circuit Timing (Ex: FM1233E)

3.3V

GND

RESET

3.3V

GND

140ms

When operating properly with 3V V_CC(for example), /RESET will

also be about 3V. When V_CCstarts to fall, /RESET will follow it

down as shown. When V_CCdrops below V_TH, /RESET drops to

ground ("issues a RESET") and stays there unless V_CCalso falls

belowitsminimumoperatingvoltage, approx. 1V. Atthispoint, the

supervisor loses control, and its output may rise, only to again

follow V_CCdown to the ground.

When V_CCbegins to rise, /RESET follows it until 1.0V or so is

reached, whereupon the device regains control, /RESET is pulled

to ground, etc. When V_CCrises above V_TH, /RESET comes out of

RESET 140 ms later.

If it is required that a lower value than GND + 1.0V is needed on

RESET signal during V_CC≤ 1V, a 100K resistor may be used on

the device output to GND.
