Pin Name
Pin Function
1
1
HTH
High-Voltage Theshold (Input): Analog input to a comparator. When the
level on this pin initially rises above V
REF
, the delay generator cycles and the
/RST remains low or RST remains high for a minimum of 140ms.
2
2
GND
Ground
3
3
LTH
Low-Voltage Threshold (Input): Analog input to a comparator. This is the
voltage monitor input assigned to detect a low voltage condition. When the
level on this pin falls below V
REF
, /RST or RST is asserted and the condition
is latched until V
HTH
> V
REF
.
Reset (Output): Push-pull output. This output is asserted and latched when
V
LTH
<V
REF
, indicating a low voltage condition. This state remains latched
until V
HTH
> V
REF
. The polarity of this signal (active-high or low) is deter
mined by the part number suffix. See ordering information.
4
RST
4
/RST
Reset (Output): Push-pull output. This output is asserted and latched when
V
LTH
<V
REF
, indicating a low voltage condition. This state remains latched
until V
HTH
> V
REF
. The polarity of this signal (active-high or low) is deter
mined by the part number suffix. See ordering information.

VDD
Power Supply (Input): Independent supply input for internal circuitry.
