LTC2915/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 programmed 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 fixed at -5%. Threshold accuracy is guaranteed at ±1.5% over the entire operating temperature range. Glitch filtering 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.
The LTC2915 and LTC2916 are low‑voltage single‑supply monitors that operate from 1.5 V to 5.5 V. They provide nine internally programmed voltage thresholds selectable via three‑state inputs, with an additional tolerance selection for the LTC2915. The devices feature low quiescent current, glitch immunity, and a manual reset input (LTC2916).\n\nThe datasheet includes electrical characteristics, pin definitions, package options (TSOT‑23 and DFN), typical performance graphs, and example applications such as dual‑supply monitoring with adjustable reset timeout. It also lists related parts and ordering information.
