Description

RESETN

Active-Low Reset Output – AS1925 Push/Pull or AS1926 Open-Drain.

RESETN changes from high to low if VCC drops below the selected reset

threshold or MRN is pulled low. RESETN remains low for the reset timeout

period (see page 4) after VCC exceeds the device reset threshold and MRN is

released high.

GND

Ground

RESET

Active-High Push/Pull Reset Output. RESET changes from low to high when

VCC input drops below the selected reset threshold or MRN is pulled low. RESET

remains high for the reset timeout period (see page 4) after VCC exceeds the

device reset threshold and MRN is released high.

4MRN

Active-Low Manual Reset Input. This pin is connected to the internal 20k

pullup to VCC. Pull this pin low to force a reset. The reset remains active as long

as MRN is low and for the reset timeout period (see page 4) after MRN goes

high.

Note: If this pin is not used it should be connected to VCC or left unconnected.

5VCC

Supply Voltage. Monitored supply voltage.
