ADM6305

Data Sheet FEATURES Adjustable input threshold voltage options: 0.4 V and 1.23 V Pre-trimmed VCC threshold options (ADM6306) Increments between 2.5 V and 5 V Manual reset input (ADM6306) 4 factory programmed reset timeout delays 1 ms, 20 ms, 140 ms, and 1.12 sec (minimum) Reset output stage: active low, open drain Low power consumption: 5 µA typical Power supply glitch immunity 5-lead SOT-23 package Temperature range: −40°C to +125°C APPLICATIONS Portable/battery-operated equipment Microprocessor systems Multivoltage applications GENERAL DESCRIPTION The ADM6305/ADM6306 are dual voltage supervisors designed to monitor two supplies and provide a reset signal to DSP- and microprocessor-based systems. Low supply current and a small form factor make these devices suitable for portable and battery-operated applications. If a monitored power supply voltage falls below the minimum voltage threshold, a single active low output asserts triggering a system reset. Once all voltages rise above...
