DS1233DZ-10 Datasheet PDF - Dallas Semiconductor

●DESCRIPTION

●The DS1233D 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 state. When VCCreturns to an in-tolerance 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

●Accurate 5%, 10% or 15% microprocessor 5V power supply monitoring

●Reduces need for discrete components

●Precision temperature-compensated voltage reference and voltage sensor

●Low-cost TO-92 package or surface mount SOT-223 package

●Internal 5 kpull-up resistor

●Compatible with Motorola 68XXX series and HC16 Microprocessors

●Operating temperature of -40°C to +85°C
