Analog Devices Inc. LTC2960HTS8-4#TRMPBF

Overview

LTC2960HTS8-4#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-comparator supervisor IC designed for battery voltage monitoring and system reset control in harsh environments. It features ADJ/IN– input configuration, 200ms fixed reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current at 36V, and operation from –40°C to 125°C. It is used in automotive battery disconnect circuits and deep-discharge protection systems.

For engineers reviewing the LTC2960HTS8-4#TRMPBF datasheet, LTC2960HTS8-4#TRMPBF pinout, LTC2960HTS8-4#TRMPBF application, or LTC2960HTS8-4#TRMPBF equivalent, key selection criteria include its IN– threshold architecture, DVCC-referenced active pull-up outputs, 200ms timeout, ±2mV ADJ/IN– threshold matching, and TSOT-23-8 package compatibility with high-temp automotive layouts.

Technical Context

The LTC2960HTS8-4#TRMPBF implements two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second uses the IN– input to detect overvoltage conditions with 5% falling hysteresis. Its internal 400mV reference enables precise threshold setting via external resistive dividers.

It operates across 2.5V–36V VCC and supports logic-level interfacing via DVCC (1.6V–5.5V), allowing RST/OUT to drive microcontroller inputs directly without external pull-ups. The device guarantees output validity down to VCC ≥ 1.2V and includes manual reset (MR) with 20µs minimum pulse width detection.

FAQ

What is the function of the DVCC pin on the LTC2960HTS8-4#TRMPBF?

The DVCC pin on the LTC2960HTS8-4#TRMPBF serves as the logic supply reference for the RST and OUT outputs. When connected to 1.6V–5.5V, it enables active pull-up operation-driving outputs high to DVCC rather than requiring external pull-up resistors. Grounding DVCC reconfigures RST/OUT as open-drain outputs. This flexibility simplifies interface design with mixed-voltage systems and reduces power consumption in battery-critical applications. The LTC2960HTS8-4#TRMPBF leverages DVCC to eliminate static current draw during low-output states.

How does the LTC2960HTS8-4#TRMPBF differ from the LTC2960HTS8-2#TRMPBF?

The LTC2960HTS8-4#TRMPBF and LTC2960HTS8-2#TRMPBF share identical temperature rating (–40°C to 125°C) and TSOT-23-8 package, but differ in output architecture and timeout configuration. The LTC2960HTS8-4#TRMPBF uses DVCC for active pull-up outputs and has a fixed 200ms reset timeout, whereas the LTC2960HTS8-2#TRMPBF uses RT pin for selectable 15ms/200ms timeout and provides 36V open-drain outputs. The LTC2960HTS8-4#TRMPBF is optimized for low-power logic interfacing; the -2 variant suits higher-voltage, resistor-pull-up designs.

Can the LTC2960HTS8-4#TRMPBF monitor both overvoltage and undervoltage conditions simultaneously?

Yes-the LTC2960HTS8-4#TRMPBF can monitor both conditions simultaneously using its dual-comparator architecture. The ADJ input detects undervoltage (reset trigger), while the IN– input detects overvoltage (e.g., battery overcharge). Each has independent hysteresis (2.5% for ADJ, 5% for IN–) and timing behavior. External resistive dividers set thresholds, and RST/OUT provide separate status signals. This eliminates the need for multiple supervisors or external comparators in battery protection circuits, making the LTC2960HTS8-4#TRMPBF ideal for compact, dual-threshold safety monitoring.

What is the minimum VCC voltage required for guaranteed RST/OUT functionality in the LTC2960HTS8-4#TRMPBF?

The LTC2960HTS8-4#TRMPBF guarantees correct RST and OUT output behavior down to VCC = 1.2V. Below this voltage, output states are not assured-even if DVCC is present-because internal biasing fails. Between 1.2V and 2.5V (the lower limit of normal operation), the device remains functional but may exhibit reduced noise immunity and timing accuracy. For robust automotive cold-crank operation, the LTC2960HTS8-4#TRMPBF's 1.2V guarantee ensures reset signaling integrity during engine start transients where battery voltage dips below 6V.

How does the LTC2960HTS8-4#TRMPBF achieve 850nA quiescent current at 125°C?

The LTC2960HTS8-4#TRMPBF achieves 850nA max ICC at 125°C through proprietary CMOS process optimization and ultra-low-leakage internal reference design. Its bandgap reference and comparator inputs are biased with picoamp-level currents, and the 400mV internal reference minimizes divider current requirements. Input leakage remains ±0.1nA at 85°C, enabling use of >10MΩ resistor networks without significant error. This nano-power performance allows the LTC2960HTS8-4#TRMPBF to operate for years on coin cells or energy-harvesting sources while maintaining full specification compliance across temperature.
