36V Nano Current Voltage Monitor Targets Multicell Applications

The LTC2960 fulfills a broad range of battery-powered, portable application requirements with its wide voltage operation and low current consumption in a tiny 2mm x 2mm DFN or ThinSOT package.

This unique feature set differentiates the LTC2960 for low power voltage monitor applications and makes it ideal for multiple Li+ coin cells, AAs, AAAs and other compact battery-powered or “green” applications. The ±1.5% accurate reset, undervoltage and overvoltage monitoring thresholds are easy to configure with external resistors. When used as a supervisor, a manual reset input is available for optional use of a pushbutton switch to force a system reset. The LTC2960-1 and LTC2960-3 provide two independent UV monitors, while the LTC2960-2 and LTC2960-4 provide one UV and one OV monitor. Ordering options include selectable 15ms or 200ms reset timeout period, output logic supply pin, or choice of active pull-up or 36V open-drain output for maximum application flexibility.

The LTC2960 is available today in commercial, industrial and automotive versions, with operating temperature ranges from 0°C to 70°C, -40°C to 85°C, and -40°C to 125°C, respectively. All devices can be ordered in either 8-pin 2mm x 2mm DFN or 8-lead ThinSOT packages, both of which are RoHS compliant. Pricing starts at $1.71 each in 1,000 piece quantities.
