Description
The Smart Reset™ devices provide a useful feature that ensures that inadvertent short reset push-button closures do not cause system resets as the extended Smart Reset™ delay setup periods are implemented. Once the valid Smart Reset™ input levels and setup delay are met, the device generates an output reset pulse for a fixed timeout period (tREC).

FEATUREs
■ Dual Smart Reset™ push-button inputs with
   capacitor-adjustable extended reset setup
   delay (tSRC)
■ No power-on reset
■ Dual RST output, active-low, open-drain
■ Fixed Smart Reset™ input logic voltage levels
■ Broad operating voltage range 1.65 V to 5.5 V,
   inactive reset output levels valid down to 1.0 V
■ Low supply current (1.5 µA)
■ Operating temperature:
   industrial grade –40 °C to +85 °C
■ TDFN8 package: 2 mm x 2 mm x 0.75 mm
■ RoHS compliant

APPLICATIONs
■ Mobile phones, smartphones
■ e-books
■ MP3 players
■ Games
■ Portable navigation devices
■ Any application that requires delayed reset
   push-button(s) response for improved system
   stability
