в–  DESCRIPTIO The LTCВ®1232 provides power supply monitoring,
watchdog timing and external reset for microprocessor
systems. A precise internal voltage reference and
comparator circuit monitor the power supply line. When
an out-of-tolerance condition occurs, the reset outputs
are forced to active states. The RST output is guaranteed
to remain logic low even with VCC as low as 1V. Guaranteed Reset Assertion at VCC = 1V
8-Pin SO Plastic Package
2.0mA Maximum Supply Current
4.62V/4.37V Precision Voltage Monitor
Power OK/Reset Time Delay: 600ms
Minimum External Component Count
Superior Upgrade for DS1232 The LTC1232 has an internal watchdog timer which forces
the reset outputs to active states when the Strobe input is …
