V6310 (obsolete, please use EM6353) Reset Circuit with over-voltage and under-voltage sense

General description

The V6310 is a CMOS device that monitors the supply voltage of any electronic system, and generates the appropriate Reset signal. The gap between the two thresholds defines the allowed voltage range. As long as VDD stays inside this voltage window, the output stays inactive. If VDD drops below VTHlow or rises above VTHhigh, the output gets active. When VDD enters into the allowed range, the output remains active for additional 50 ms (typ.). This allows the system to stabilize before getting fully active. The lower threshold voltage may be obtained in different versions: 2.0 V to 6 V 2.4 V to 6 V 2.8 V to 6 V 3.5 V to 6 V 4.0 V to 6 V 4.5 V to 6 V

Features

• Voltage Window monitoring • Clear microprocessor restart after power up • Processor reset at power down • Reset output guaranteed down to VDD = 1V • Low power consumption: typ. 3mA at VDD = 5V • -40 to +85°C temperature range • On-chip oscillator • No external components required • Push-pull or Open drain output • TO-92, SOT-23 5L and SOT-223 packages • Pin compatible with DS 1233 A in TO-92 (SOT-223 on request)

Applications
