NAME
FUNCTION
Set Reset Timeout Input. Connect a capacitor between SRT and ground to
1
SRT
set the timeout period. Determine the period as follows:
t_RP = 2.6 × 10⁶ × C_SRT + 340 × 10^-6
with t_RP in seconds and C_SRT in farads.
2
GND
Ground.
3
N.C.
Not Internally Connected. Can be connected to GND.
4
V_CC
Supply Voltage and Reset Threshold Monitor Input.
RESET changes from high to low whenever VCC drops below the selected
5
RESET
reset threshold voltage. RESET remains low for the reset timeout period
after V_CC exceeds the reset threshold.
