MAX6316MAX6322 5-Pin P Supervisory Circuits with Watchdog and Manual Reset General Description Benefits and Features Integrated Configuration Enables Flexible Designs The MAX6316MAX6322 family of microprocessor (P) Available in 26 Reset-Threshold Voltages supervisory circuits monitors power supplies and micro- - 2.5V to 5V, in 100mV Increments processor activity in digital systems. It offers several com- Four Reset Timeout Periods binations of push/pull, open-drain, and bidirectional (such - 1ms, 20ms, 140ms, or 1.12s (min) as Motorola 68HC11) reset outputs, along with watchdog Four Watchdog Timeout Periods and manual reset features. The Selector Guide below lists - 6.3ms, 102ms, 1.6s, or 25.6s (typ) the specific functions available from each device. Four Reset Output Stages These devices are available in 26 factory-trimmed reset - Active-High, Push/Pull threshold voltages (from 2.5V to 5V, in 100mV increments), - Active-Low, Push/Pull featuring four minimum power-on reset timeout periods - Active-Low, Open-Drain (from 1ms to 1.12s), and four watchdog timeout periods - Active-Low, Bidirectional (from 6.3ms to 25.6s). Thirteen standard versions are Integrated Features Increase Robustness available with an order increment requirement of 2500 Guaranteed Reset Valid to V = 1V CC pieces (see Standard Versions table) contact the factory Immune to Short-Negative V Transients CC for availability of other versions, which have an order Saves Board Space increment requirement of 10,000 pieces.
