n General Description

n Typical Operating Circuit

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.

Input

RESET /

RESETB

These circuits monitor the power supply voltage of mP

based systems. When the power supply voltage drops

below the voltage threshold a reset is asserted immedi-

ately (within an interval T_D1). The reset remains asserted

after the supply voltage rises above the voltage threshold

GND

for a time interval, T . 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.

Note: * External pull-up resistor is required if open-

drain output is used. 10 kW is recommended.

Space saving SOT23/TSOT-23 packages and

micropower quiescent current (<3.0mA) make this family

a natural for portable battery powered equipment.
