Micrel
General Description
The MIC2772 is a dual power supply supervisor that providesunder-voltage monitoring and power-on
reset generation. It may replace two discrete voltage supervisors suchas MIC1810, MIC1815, MIC809, MIC811, MIC6315, etc. The two voltage supervisors are completely independent. Each functional block featuresanunder-voltage detector, a delay-generator, and a de-bounced manualreset input.
FEATUREs
• Two independent voltage supervisors
• Directly replacesdiscrete supervisors
• Generates power-on reset pulses
• De-bounced manual reset Inputs
• Choice of voltage thresholds
• 20, 140, or 1100ms reset timeouts
• Reset output may be pulled above VCC
• Rejects brief input transients
• Ultra-small 2x2mm MLF package
