FEATURES

LTC1998

2.5µA, 1% Accurate

SOT-23 Comparator and Voltage

Reference for Battery Monitoring

DESCRIPTION

The LTC

1998 is a micropower comparator and a precision

adjustable reference in a 6-pin SOT-23 package that is

optimized for lithium-ion low battery detection circuits.

The LTC1998 features a voltage detection circuit with an

adjustable threshold voltage and hysteresis. The threshold

voltage can be programmed from 2.5V to 3.25V with two

external resistors. A 10mV to 750mV hysteresis can be

added with a third external resistor.

A proprietary internal architecture maintains 1% thresh-

old voltage accuracy over temperature with low cost 1%

external resistors.

A separate power supply pin, V

LOGIC,

allows the battery-low

logic output to operate below the battery voltage, allowing

compatibility with low voltage microprocessors without a

pull-up resistor. Power supply glitches are eliminated by

preventing the cross-conducting current which occurs

when the output changes state.

The LTC1998 operates with battery or supply voltages

up to 5.5V and its battery-low output is valid for battery

voltages above 1.5V.

High Accuracy Trip Voltage: 1% Max Error Using

External 1% Resistors

Adjustable Threshold Voltage and Hysteresis

Quiescent Current: 2.5μA Typ

Output Swings Rail-to-Rail

Thresholds Programmable from 2.5V to 3.25V

Output State Guaranteed for V
