  DESIGN FEATURES Adjustable Low-Battery Threshold
  Detector Extends Battery Runtime
  by Brendan Whelan
  The LTC1998 is the first LithiumIon low-battery detector that
  guarantees 1% accuracy even when
  using inexpensive 1% programming
  resistors. This device facilitates more
  reliable battery capacity management;
  it extends battery runtime and
  improves prediction of remaining battery charge. The LTC1998 achieves
  this performance by combining an
  accurate internal reference and a proprietary comparison circuit. Other
  features include:
  вќЏ Low supply current, 2.5ВµA
  typical
  вќЏ Adjustable low-battery threshold,
  2.5V to 3.25V
  вќЏ Adjustable hysteresis, 10mV to
  750mV
  вќЏ Rail-to-rail push-pull output
  eliminates pullup resistor
  вќЏ Dedicated output supply pin
  ensures compatibility with …
