LTC2960HDC-1

Supervisors Overview

The LTC2960HDC-1 is a dual-input voltage supervisor manufactured by Analog Devices Inc., designed for high-voltage monitoring applications. It operates within a supply voltage range of 2.5V to 36V and consumes only 850nA of quiescent current, making it suitable for battery-powered systems. The device features two adjustable input channels (IN+ and IN-) configured for under-voltage or over-voltage detection via external resistive dividers. It provides a manual reset (MR) input and an active push-pull RST output with a fixed 200ms reset timeout. The component is housed in a compact 2mm x 2mm DFN-8 package and supports operation across the industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Dual independent voltage monitoring inputs configurable for under-voltage or over-voltage thresholds using external resistors
• Ultra-low 850nA static current consumption to extend battery life in portable applications
• Manual reset capability allowing system initialization via external button press
• Active push-pull output driver with fixed 200ms reset delay for reliable microprocessor reset signaling

Supervisors Applications

• Multi-cell battery pack monitoring and low-battery indication
• Under-voltage lockout (UVLO) protection for DC/DC converters and LDOs
• Power sequence control in complex embedded systems
• High-voltage window comparison for automotive electronic subsystems

Supervisors Procurement Notes

Verify the specific suffix HDC-1 against the manufacturer's datasheet to confirm the active push-pull output configuration and the extended -40°C to +125°C operating temperature range. Ensure that the required reset timeout matches the fixed 200ms specification, as other variants in the series offer different timing options. Confirm RoHS compliance status and packaging type requirements prior to ordering.

Supervisors Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside minimal standby current. The LTC2960HDC-1 is appropriate for designs needing simultaneous under-voltage and over-voltage supervision on two distinct rails. Consider the fixed 200ms reset delay; if programmable timing is necessary, alternative models such as the LTC2960ITS8-1 should be evaluated instead.

Supervisors Part Context

The LTC2960 series represents Analog Devices' solution for supervisory circuits requiring high voltage tolerance and low power consumption. This specific part belongs to the HDC family, which distinguishes itself through the inclusion of an active push-pull output stage rather than an open-drain configuration. This feature simplifies interface design by eliminating the need for external pull-up resistors while maintaining compatibility with standard logic levels.

Supervisors FAQ

What is the reset timeout duration for the LTC2960HDC-1?

The LTC2960HDC-1 has a fixed reset timeout of 200ms. Unlike other variants in the series, it does not support programmable timing selection.

How are the monitoring thresholds configured?

Thresholds are set externally using resistive voltage dividers connected to the IN+ and IN- pins. The internal comparator triggers the reset output based on these user-defined voltage levels.
