General Description:
The AME8500 family allows the user to customize the CPU reset function without any external
components. The user has a large choice of reset voltage thresholds, reset time intervals, and output driver
configurations, all of which are preset at the factory. Each wafer is trimmed to the customer'
s specifications.
These circuits monitor the power supply voltage of µP based systems. When the power supply voltage
drops below the voltage threshold a reset is asserted immediately (within an interval TD1). The reset
remains asserted after the supply voltage rises above the voltage threshold for a time interval, TD2 . The reset
output may be either active high (RESET) or active low (RESETB). The reset output may be configured as either
push/pull or open drain. The state of the reset output is guaranteed to be correct for supply voltages greater than
1V.
Space saving SOT-23/TSOT-23 packages and micropower quiescent current (<3.0
natural for portable battery powered equipment.

Failures In Time Calculation:
Use HTOL test information mentioned in section
FIT = ( x 2 (ν ,
CL )
, FIT (Failures In Time) can be calculated as below:
× 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 )
9
=106.69 (pieces per 10 hours) @ 40
with 90% Confidence Level.
Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
