INTEGRATED CIRCUITS SA56606-XX CMOS system reset Product data Supersedes data of 2001 Apr 24 File under Integrated Circuits, Standard Analog 2001 Jun 19 Philips Semiconductors Philips Semiconductors Product data CMOS system reset SA56606-XX GENERAL DESCRIPTION The SA56606-XX is a CMOS device designed to generate a reset signal for a variety of microprocessor and logic systems. Accurate reset signals are generated during momentary power interruptions or whenever power supply voltages sag to intolerable levels. An Open Drain output topology is incorporated for adaptability to a wide variety of logic and microprocessor applications. Several reset threshold versions of the device are available. The SA56606-XX is available in the SOT23-5 surface mount package. FEATURES • 12 VDC maximum operating voltage • CMOS N-channel Open Drain output • Offered in reset thresholds of • Available in SOT23-5 surface mount package SIMPLIFIED SYSTEM DIAGRAM VDD 2 VDD APPLICATIONS 2.0, 2.7, 2.8, 2.9, 3.0, 3.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7 VDC • Microcomputer systems • Logic systems • Battery monitoring systems • Back-up power supply circuits • Voltage detection circuits VDD SA56606-XX R VOUT RPU CPU VREF R R 1 RESET VSS 3 VSS VSS SL01313 Figure 1.
