Analog Devices Inc. LTC2960HDC-2#TRMPBF

Overview

LTC2960HDC-2#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery and automotive power monitoring. It features ADJ/IN– input configuration, 200ms fixed reset timeout, 36V open-drain RST/OUT outputs, ±2mV ADJ/IN– threshold matching, and operates from –40°C to 125°C. It is used in battery disconnect circuits to prevent deep discharge in Li-ion systems.

For engineers reviewing the LTC2960HDC-2#TRMPBF datasheet, LTC2960HDC-2#TRMPBF pinout, LTC2960HDC-2#TRMPBF application, or LTC2960HDC-2#TRMPBF equivalent, key selection criteria include its IN– comparator architecture, 850nA quiescent current at 36V, 1.5% threshold accuracy over temperature, 36V absolute max VCC rating, and compatibility with high-side sensing in automotive brown-out detection.

Technical Context

The LTC2960HDC-2#TRMPBF implements dual-comparator supervision: one dedicated ADJ input for reset threshold detection with 2.5% hysteresis, and a second IN– input configured for overvoltage detection-pulling OUT low when monitored voltage rises above threshold and releasing it only after falling below threshold minus 5% hysteresis. Its internal 400mV reference enables precise external resistor-divider programming.

It supports manual reset via MR input with 20µs minimum pulse width detection and 1–20µs propagation delay, and guarantees output low state for VCC ≥ 1.2V. The 36V open-drain outputs tolerate pull-up voltages up to 40V, enabling direct interface with higher-voltage logic or MOSFET gate drivers without level-shifting.

FAQ

What is the reset timeout period for LTC2960HDC-2#TRMPBF?

The LTC2960HDC-2#TRMPBF has a fixed 200ms reset timeout period. Unlike the -1 variant, it does not include an RT pin for selection between 15ms and 200ms; the timeout is internally hardwired. This value applies to both automatic reset recovery after ADJ voltage rise and manual reset release after MR input returns high. The specification is guaranteed over –40°C to 125°C.

Does LTC2960HDC-2#TRMPBF support overvoltage detection?

Yes, LTC2960HDC-2#TRMPBF supports overvoltage detection via its IN– input. When the voltage at IN– rises above the programmed threshold, the OUT output pulls low. OUT remains low until the IN– voltage falls below the threshold minus 5% hysteresis (18–25mV). This behavior is explicitly defined for LTC2960-2 and LTC2960-4 variants, and LTC2960HDC-2#TRMPBF is the high-temp (-40°C to 125°C) DFN-packaged version of LTC2960-2.

What is the maximum input voltage allowed on the ADJ, IN+, or IN– pins of LTC2960HDC-2#TRMPBF?

The absolute maximum voltage on ADJ, IN+, or IN– pins of LTC2960HDC-2#TRMPBF is –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. To monitor higher voltages (e.g., 36V battery), external resistive dividers must scale the input down to ≤3.5V while maintaining threshold accuracy - e.g., a 10:1 divider reduces 36V to 3.6V, so design must ensure worst-case scaled voltage stays within limit.

Can LTC2960HDC-2#TRMPBF operate with VCC = 2.5V?

Yes, LTC2960HDC-2#TRMPBF is fully specified to operate with VCC as low as 2.5V. At this voltage, the RST and OUT outputs remain functional as 36V open-drain drivers, and all electrical characteristics-including 850nA max quiescent current, ±1.5% threshold accuracy, and 200ms timeout-are guaranteed over the full –40°C to 125°C range. Below 2.5V, operation is not assured.

Is the exposed pad on the DFN package of LTC2960HDC-2#TRMPBF required to be connected to ground?

No, the exposed pad (pin 9) on the LTC2960HDC-2#TRMPBF DFN package may be left electrically floating or connected to GND - both configurations are acceptable per the datasheet. Connecting it to GND improves thermal performance slightly (θJA = 80.6°C/W vs. ~95°C/W if floating), but is not required for electrical functionality or reliability. PCB layout should follow Analog Devices' recommended land pattern for mechanical stability.
