AME8510 / 8520 / 8530

Micropower

µµµµµP Watch Dog Timer

l Small packages: SOT-25

l 7 voltage threshold options

l Tight voltage threshold tolerance ---±1.50%

l 12 output driver configuration options

l Wide temperature range -------- -40oC to 85oC

l Low temperature coefficient --- 100ppm/o(max)

l Low quiescent current < 3.0µA

l 3 bonding options

The AME8510/8520/8530 family allows the user to cus-

tomize the CPU monitoring function without any external

components. The user has a large choice of reset volt-

age thresholds and output driver configurations, all of

which are preset at the factory. Each wafer is trimmed

to the customer's specifications.

These circuits will ignore fast negative going transients

on V

DD. The state of the reset output is guaranteed to be

correct down to 1V.

After V

DD crosses above a factory preset threshold,

the AME8510/8520/8530 assert a reset signal. After a

predetermined time (the “reset” interval) the reset is

deasserted. If V

DD ever drops below the threshold voltage

a reset is asserted immediately. In addition to a supply

monitoring function the AME8510/8520 also monitor tran-

sitions at the watch dog (WDI) input. If a logic transition

does not occur at the WDI pin within a certain time inter-

val (the “watchdog” interval) then a reset is asserted. The

reset deasserts after the reset interval, as explained ear-

lier.

The AME8510/8530 can both assert a reset manually

by pulling the MRB input to ground.

Space saving SOT-25 packages and micropower qui-

escent current make this family a natural for portable

battery powered equipment.
