Description

The ICL7665SCBA is one member of the ICL7665S series.The ICL7665S super CMOS micropower over/under voltage detector contains two low power, individually programmable Voltage detectors on a single CMOS chip.Requiring typically 3A for operation, the device is intended for battery-operated systems and instruments which require high or low voltage warnings, settable trip points, or fault monitoring and correction. The trip points and hysteresis of the two voltage detectors are individually programmed via external resistors.An internal bandgap-type reference provides an accurate threshold voltage while operating from any supply in the 1.6V to 16V range.

Features of the ICL7665SCBA are:(1)guaranteed 10A maximum quiescent current over temperature; (2)guaranteed wider operating voltage range over entire operating temperature range; (3)2% threshold accuracy (ICL7665SA); (4)dual comparator with precision internal reference ; (5)100ppm/ temperature coefficient of threshold voltage; (6)100% tested at 2V; (7)output current sinking ability: up to 20mA; (8)individually programmable upper and lower trip voltages and hysteresis levels.If the SET voltages must be applied before the supply voltage V+, the input current should be limited to less than 0.5mA by appropriate external resistors, usually required for voltage setting anyway. A similar precaution should be taken with the outputs if it is likely that they will be driven by other circuits to levels outside the supplies at any time.

The absolute maximum ratings of the ICL7665SCBA can be summarized as:(1)supply voltage:-0.3 to 18V;(2)maximum source output current:-25mA;(3)storage temperature:-65 to 150;(4)lead temperature:300.The ICL7665S, super programmable over/under voltage detector is a direct replacement for the industry standard ICL7665B offering wider operating voltage and temperature ranges, improved threshold accuracy (ICL7665SA), and temperature coefficient, and guaranteed maximum supply current. All improvements are highlighted in the electrical characteristics section.All critical parameters are guaranteed over the entire commercial and industrial temperature ranges.For these reasons, it is recommended that no inputs from external sources not operating from the same power supply be applied to the device before its supply is established,and that in multiple supply systems,the supply to the ICL7665SCBA be turned on first. If this is not possible, current into inputs and/or outputs must be limited to ±0.5mA and voltages must not exceed those defined above.
