Hot-selling and scarce LTC1998CS6 2.5uA, 1% Accurate SOT-23 Comparator for Battery Monitoring spot stock

Product Descriptions

The LTC^®1998 is a micropower comparator and a precision adjustable reference in a 6-pin SOT-23 package thatis optimized for lithium-ion low battery detection circuits .

The LTC1998 features a voltage detection circuit with anadjustable threshold voltage and hysteresis . The threshold voltage can be programmed from 2.5V to 3.25V withtwo external resistors . A 10mV to 750mV hysteresis canbe added with a third external resistor .

A proprietary internal architecture maintains 1%threshold voltage accuracy over temperature with low cost 1%external resistors .

A separate power supply pin, V LOGIC, allows the batterylow logic output to operate below the battery voltage,allowing compatibility with low voltage microprocessorswithout  a  pull-up  resistor .  Power  supply  glitches  areeliminated by preventing the cross-conducting currentwhich occurs when the output changes state .

The LTC1998 operates with battery or supply voltages upto 5.5V and its battery-low output is valid for batteryvoltages above 1.5V .
