description:

Linear Technology Corporation introduces the LTC2960, a 2.5V to 36V, two-input voltage monitor that draws only 850nA of quiescent current to extend battery life in battery-powered applications. The LTC2960 provides two adjustable monitor inputs that can be configured to provide undervoltage (UV) or overvoltage (OV) monitoring, low battery indication, undervoltage lockout (UVLO), power sequencing signals, or microprocessor-oriented High-voltage window comparators are available for DC/DC switches or LDO-based systems. Available in a tiny 2mm x 2mm DFN or ThinSOTTM package, the LTC2960 meets the needs of a wide range of battery-powered portable applications with a wide operating voltage range and low current consumption.

The unique features make the LTC2960 unique, ideal for low-power voltage monitor applications, and ideal for multi-cell Li-Ion coin-cell, AA, AAA batteries and other compact battery-powered or “green” applications. Reset, undervoltage, and overvoltage monitoring thresholds with an accuracy of ±1.5% are easily configured with external resistors. When used as a monitor, a manual reset input is also provided to force a system reset using the optional push button switch. The LTC2960-1 and LTC2960-3 provide two independent undervoltage monitors, while the LTC2960-2 and LTC2960-4 provide an undervoltage and an overvoltage monitor. Ordering options include an optional 15ms or 200ms reset timeout length, an output logic supply pin, or an active pull-up or 36V open-drain output to maximize application flexibility.
