Analog Devices Inc. LTC2960HTS8-3#TRMPBF

Overview

LTC2960HTS8-3#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 850nA quiescent current, 2.5V–36V VCC operation, ±2mV ADJ/IN+ threshold matching, fixed 200ms reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It is used in automotive battery management systems to detect low-voltage brownout conditions before critical shutdown.

For engineers reviewing the LTC2960HTS8-3#TRMPBF datasheet, LTC2960HTS8-3#TRMPBF pinout, LTC2960HTS8-3#TRMPBF application, or LTC2960HTS8-3#TRMPBF equivalent, key selection criteria include its 200ms fixed timeout, TSOT-23-8 package with exposed pad, –40°C to 125°C operating range, DVCC-referenced push-pull outputs, and dual-threshold monitoring capability for multicell Li-ion stacks.

Technical Context

The LTC2960HTS8-3#TRMPBF integrates two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second monitors IN+ for configurable status signaling with 5% hysteresis. Its internal 400mV reference enables precise threshold setting via external resistive dividers across up to 36V inputs.

Unlike variants with RT pin or open-drain outputs, this part replaces RT with DVCC to support logic-level output swing control (1.6V–5.5V), enabling direct interface with low-voltage microcontrollers without external pull-ups. Input leakage is ≤±0.1nA at –40°C to 85°C, ensuring minimal divider error in high-impedance sensing networks.

FAQ

What is the maximum input voltage the ADJ and IN+ pins of the LTC2960HTS8-3#TRMPBF can tolerate?

The ADJ and IN+ pins of the LTC2960HTS8-3#TRMPBF have an absolute maximum rating of –0.3V to 3.5V. This limits the directly applied voltage but enables monitoring of higher system voltages (e.g., 36V battery rails) via external resistive dividers. For a 36V input, the divider must scale the voltage to ≤3.5V at the pin - for example, a 10:1 ratio yields 3.6V at 36V, so a 10.3:1 or higher ratio is required. The LTC2960HTS8-3#TRMPBF's ±0.1nA input leakage ensures minimal error in high-impedance divider networks.

Does the LTC2960HTS8-3#TRMPBF support manual reset functionality, and how is it implemented?

Yes, the LTC2960HTS8-3#TRMPBF includes a dedicated MR (Manual Reset) input that pulls RST low when driven to GND. After release, RST remains low for the full 200ms reset timeout period before returning high. The MR pin has a 0.4V–1.4V logic threshold and draws ≤–1µA when pulled low, allowing direct interface with pushbuttons or GPIOs. Unlike variants with RT pin, the LTC2960HTS8-3#TRMPBF retains MR functionality while replacing RT with DVCC for output logic control - preserving reset flexibility without sacrificing output drive capability.

How does the DVCC pin affect the behavior of RST and OUT on the LTC2960HTS8-3#TRMPBF?

On the LTC2960HTS8-3#TRMPBF, the DVCC pin sets the high-level voltage for both RST and OUT outputs. When DVCC is connected to a 1.6V–5.5V supply, outputs actively drive to that voltage (push-pull mode), eliminating external pull-up resistors. If DVCC is grounded, RST and OUT become open-drain and require external pull-ups. This dual-mode capability allows the same LTC2960HTS8-3#TRMPBF to interface with 1.8V, 3.3V, or 5V logic domains without redesign. The DVCC pin also enables valid outputs even when VCC drops near ground - a critical feature for fail-safe automotive monitoring.

What is the accuracy of the reset threshold over temperature for the LTC2960HTS8-3#TRMPBF?

The LTC2960HTS8-3#TRMPBF guarantees ±1.5% maximum reset threshold accuracy over its full operating temperature range of –40°C to 125°C. This specification applies to the ADJ input's 400mV internal reference, which sets the falling threshold. Combined with ±2mV ADJ/IN+ threshold matching, this ensures consistent dual-threshold behavior across temperature - essential for applications like battery cutoff and warning where relative offset must remain stable. The 2.5% hysteresis further prevents chatter during slow supply ramps.

Can the LTC2960HTS8-3#TRMPBF be used in automotive under-hood applications, and what qualifications support this?

Yes, the LTC2960HTS8-3#TRMPBF is explicitly rated for –40°C to 125°C operation and is widely deployed in automotive under-hood applications including battery disconnect units, start-stop systems, and ADAS power supervisors. While not formally AEC-Q200 certified in this specific variant, its DC electrical characteristics, thermal performance, and package construction align with AEC-Q200 stress test requirements. Its 36V VCC rating handles load dump transients, and the TSOT-23 package with exposed pad ensures robust thermal dissipation in high-ambient environments - making the LTC2960HTS8-3#TRMPBF a de facto standard for automotive-grade voltage supervision.
