LTC2935CDC-3

Supervisors Overview

The LTC2935CDC-3#PBF is a single-channel ultra-low power voltage supervisor manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and consumes only 500 nA of quiescent current. The device features an open-drain output with active-low reset functionality and includes manual reset capability. It offers eight selectable threshold voltage combinations, specifically ranging from 1.6 V to 2.44 V in 0.12 V increments. The component provides a minimum reset timeout of 140 ms and maintains accuracy within 1.5%. It is housed in an 8-lead DFN package measuring 2x2 mm and supports surface mount installation.

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel or tube packaging as per manufacturer standards. Confirm availability status, as this part may be discontinued or subject to limited supply constraints. Ensure compatibility with RoHS3 and REACH regulations for your target market. Cross-reference the exact threshold code '3' against official datasheets to validate the precise voltage selection before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with low quiescent current is required. The open-drain output necessitates an external pull-up resistor. Verify that the selected threshold combination matches the monitored rail voltage. Consider the 8-DFN package size for space-constrained PCB layouts. Ensure the operating temperature range meets the environmental requirements of the final application.
