LTC2966ISW#PBF

Supervisors Overview

The LTC2966ISW#PBF is a dual-input voltage supervisor manufactured by Analog Devices Inc., housed in a 16-pin SOIC package. It monitors two independent supply rails with adjustable thresholds and features an open-drain reset output. The device operates within a supply voltage range of 2.5 V to 100 V, drawing only 7 µA of quiescent current. It supports manual reset functionality and includes a fixed 200 ms reset delay time. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match your design requirements. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the operating voltage range aligns with your target supply rails before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with minimal power overhead. The wide input voltage range accommodates various bus architectures. Consider the open-drain output compatibility with your logic levels. Verify that the adjustable thresholds meet your specific trip point requirements without external resistor networks if possible.

Supervisors Part Context

This part belongs to the LTC2966 series of microprocessor supervisors designed for high-voltage applications. It complements other Analog Devices PMIC solutions by providing reliable fault detection for critical power rails. The series emphasizes low standby current and robust performance in harsh environments, fitting into broader system power management strategies.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the LTC2966CUD variant, ensuring package compatibility. Verify that any substitute maintains the 100 V maximum input rating and similar quiescent current specifications. Cross-reference datasheets for threshold adjustability and reset delay times to ensure functional equivalence.
