TI LM3710XQBP-308

The LM3710/LM3711 series of microprocessor supervisory circuits provide the maximum flexibility for monitoring power supplies and battery controlled functions in systems without backup batteries.

• Reset: Reset is asserted during power-up, power-down, and brownout conditions. RESET is guaranteed down to V_CC of 1.0V.
• Manual Reset Input: An input that asserts reset when pulled low.
• Power-Fail Input: A 1.225V threshold detector for power fail warning, or to monitor a power supply other than V_CC.
• Low Line Output: This early power failure warning indicator goes low when the supply voltage drops to a value which is 2% higher than the reset threshold voltage.
• Watchdog Timer: The WDI (Watchdog Input) monitors one of the μPs output lines for activity. If no output transition occurs during the watchdog timeout period, reset is activated.
• Standard Reset Threshold voltage: 3.08V
• No external components required
• Manual-Reset input
• RESET (LM3710) or RESET (LM3711) outputs
• Precision supply voltage monitor
• Factory programmable Reset and Watchdog Timeout Delays
• Separate Power Fail comparator
• Available in micro SMD package for minimum footprint
• ±0.5% Reset threshold accuracy at room temperature
• ±2% Reset threshold accuracy over temperature extremes
• Reset assertion down to 1V_V_CC (RESET option only)
• 28 μA V_CC supply current

• Embedded Controllers and Processors
• Intelligent Instruments
• Automotive Systems
• Critical μP Power Monitoring
