VCC = 3.3V, TA = Operating Temperature Range, unless otherwise noted. Parameter Conditions Min Typ Max Units Operating Voltage Range, VCC TA = 0°C to 70°C 1.4 5.5 V TA = -40°C to 85°C 1.6 5.5 Supply Current, ICC µA Reset Voltage Threshold, VTH MIC1815-10 2.80 2.88 2.97 V MIC1815-20 2.47 2.55 2.64 Reset Timeout Period 100 150 250 ms RESET Output Voltage, VOH ISource = 800µA VCC - 1.5V V RESET Output Voltage, VOL VCC=VTH Min., ISink=1.2mA 0.4 V VCC>1.4V, ISink =50µA 0.3 Stresses above those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent device failure. Functionality at or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability. Operating ranges define those limits between which the functionality of the device is guaranteed. Absolute Maximum Ratings Terminal Voltage 20mA Operating Temperature Range MIC1815 Microprocessor Reset Circuit
RESET goes low if VCC falls below the reset threshold and remains asserted for one reset timeout period (100ms min.) after VCC exceeds the reset threshold. Power supply input, 3.3V. IC Ground Pin. Pin Name Pin No. RESET VCC GND MIC1815 Microprocessor Reset Circuit
