LTC2909CTS8-3.3 Description

Short technical summary and product information.

The LTC2909CTS8-3.3 is a precision supervisor IC from Linear Technology designed for monitoring triple or dual input voltage supplies. It features adjustable input thresholds with pin-selectable polarity, allowing for monitoring of both positive and negative voltages for undervoltage (UV) and overvoltage (OV) conditions. The device boasts a guaranteed threshold accuracy of ±1.5% and a minimum reset level of 0.5V.

 

Key electrical characteristics include a 6.5V shunt regulator for high voltage operation and a low quiescent current of 50µA. It supports power-up/down resets with an adjustable pulse width and offers a buffered 1V reference for negative supply offset. The LTC2909CTS8-3.3 operates within a temperature range of -40°C to 85°C and is housed in a SOT-23 package, suitable for surface mounting.

 

This supervisor IC is ideal for applications requiring robust power supply monitoring to prevent system failures due to voltage fluctuations. Its customizable nature allows designers to set specific trip thresholds tailored to their system requirements.
