1 / 8 page  _______________General Description In applications with microprocessors (µPs) that have a RESET input, the MAX7705 is functionally and socket compatible with the TL7705, but requires no external components. It provides power-supply glitch immunity and a guaranteed power-up reset delay, while typically consuming 1/27th the power from a +5V supply. The MAX7705 monitors the power supply in µP and digital systems. The RESET output is valid for VCC down to 1V. The device offers excellent circuit reliability and low cost by eliminating external components and adjustments. A system reset is provided during power-up, power- down, and brownout conditions. When VCC is below the reset threshold, RESET is low and holds the µP in reset. RESET will go high 280ms after VCC rises above the reset threshold. The MAX7705 is available in 8-pin DIP and SO packages. ________________________Applications Minimum Component Count, Low-Cost Processor Systems ____________________________Features o No External Components o Low Cost o Precise Reset Threshold o 280ms Power-On Reset Delay o 8-Pin DIP and SO Packages ______________Ordering Information * Contact factory for dice specifications. µP Power-Supply Monitor with Reset ________________________________________________________________ Maxim Integrated Products 1 1 2 3 4 8 7 6 5 VCC N.C.
