Overview
Key Features: • LOW STANDBY CURRENT • INTERNAL VOLTAGE THRESHOLD AT 2.95V • TEMPERATURE COMPENSATED BANDGAP REFERENCE • PRECISION COMPARATOR WITH 40MV OF HYSTERESIS • CLAMP DIODE FOR DISCHARGING DELAY CAPACITOR • OUTPUT CURRENT SINK CAPABILITY (typ 5mA) • 1-10V INPUT SUPPLY RANGE • AVAILABLE IN 150MIL, 8-PIN SOIC AND 3-PIN TO-92 PACKAGES The SG3546 is an undervoltage sensing circuit specifically designed for use as a reset controller in 3.3V microprocessor-based applications. Its micropower operation makes this device ideal for portable applications where extended battery life is required. The device offers a 1.2V temperature compensated bandgap reference, a precision comparator with hysteresis and a high-current open collector output. This device operates from 1 to 10V input supply and drains <10µA in the non-fault condition. The SG3546 is available in an 8-pin 150mil SOIC package or a 3-pin TO-92 package and is rated for an ambient temperature of 0°C to 70°C. |
