DESCRIPTION
Voltage Supervisor with
27 Selectable Thresholds
The LTC
®
2915/LTC2916 are low voltage single-supply
monitors with selectable thresholds. The parts operate
from 1.5V to 5.5V and consume a quiescent current of
only 30μA.
Two three-state inputs select one of nine internally pro-
grammed thresholds without the need for external resistors.
For the LTC2915, an additional three-state input determines
the tolerance (–5%, –10%, –15%). The tolerance for the
LTC2916 is fi xed at –5%. Threshold accuracy is guaranteed
at ±1.5% over the entire operating temperature range.
Glitch fi ltering ensures reliable reset operation without
false triggering.
The reset timeout may be set to 200ms or adjusted using
an external capacitor. A separate manual reset input on the
LTC2916 allows a simple push button interface.
Operation to 125°C makes the LTC2915 and LTC2916
suitable for automotive applications.
