Pin Configuration
°
The APR3101/2/3 are designed to monitor voltage
supplies in µP and digital systems. The quiescent
current is extremely low, typically 1.5 µA, making it
ideal for portable battery operated equipment. The
APR3101/2/3 operate by monitoring the system power
supply voltage. When the input voltage drops below a
fixed threshold or whenever manual reset is asserted,
the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold or manual
reset is deasserted. The APR3101/2/3 series is available with three output stage versions:APR3101 pushpull active low output, APR3102 push-pull active high
output and APR3103 open drain active low output. The
APR3101/2/3 also have a debounced manual reset
input that is provided to override the reset monitor.
They are also designed to reject fast line transient
glitches on Vcc. The APR3101/2/3 are come in a
miniature SOT-23-5 package.

RESET
(APR3101/3)
RESET output remains low while VCC is below the reset threshold and remains
so for a fixed time period after V
CC
raises above the reset threshold.

RESET
(APR3102)
RESET output remains high while V
CC
is below the reset threshold and remains
so for a fixed time period after V
CC
raises above the reset threshold.
4 MR
Manual Reset active low input. A logic low signal on MR asserts a reset
condition. Asserted reset c ontinues as long as MR is lo w and for a fixed time
period after MR returns high.
5 VCC Supply Voltage (+1.2V to +6V)
