DESCRIPTION
The DS1233M EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active (low) state. When VCCreturns to an intolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the power supply and processor to stabilize.
FEATURES
Automatically restarts microprocessor after power failure
Maintains reset for 350 ms after VCC returns to an in-tolerance condition

Precision temperature-compensated voltage reference and voltage sensor
Low-cost TO-92 package or surface mount 8-pin SOIC packages available
Internal 5 kpullup resistor
Compatible with Motorola 68XXX series and HC16 Microprocessors
Pin function compatible with the Motorola MC33064, MC34064, MC33164, and MC34164
