Analog Devices Inc. LTC2960HTS8-1#TRMPBF

Overview

LTC2960HTS8-1#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input voltage supervisor IC designed for battery monitoring and system reset control in harsh environments. It features 850nA quiescent current, 36V VCC operation, ±2mV ADJ/IN+ threshold matching, and 15ms/200ms selectable reset timeout - used to monitor multicell Li-ion battery packs and trigger controlled shutdown before deep discharge.

For engineers reviewing the LTC2960HTS8-1#TRMPBF datasheet, LTC2960HTS8-1#TRMPBF pinout, LTC2960HTS8-1#TRMPBF application, or LTC2960HTS8-1#TRMPBF equivalent, key selection criteria include its 36V open-drain RST/OUT outputs, –40°C to 125°C operating range, RT pin-based timeout selection, adjustable ADJ/IN+ thresholds via external dividers, and compatibility with automotive and industrial battery management systems requiring ultra-low ICC and wide input voltage tolerance.

Technical Context

The LTC2960HTS8-1#TRMPBF implements dual independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and programmable timeout, while the second monitors IN+ for auxiliary voltage detection with 5% hysteresis. Its internal 400mV reference enables precise threshold setting across temperature.

It operates from 2.5V to 36V VCC, draws only 850nA typical supply current at 36V over full temperature range, and supports manual reset (MR) with 20µs minimum pulse width. The RT pin selects between 15ms and 200ms reset timeout periods, and both RST and OUT outputs are 36V-tolerant open-drain with ±5mA drive capability.

FAQ

What is the maximum input voltage the ADJ and IN+ pins of the LTC2960HTS8-1#TRMPBF can tolerate?

The ADJ and IN+ pins of the LTC2960HTS8-1#TRMPBF have an absolute maximum rating of –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. When monitoring high-voltage sources (e.g., 24V battery), external resistive dividers must scale the input to stay within this range - for example, a 10:1 divider reduces 35V to 3.5V. This constraint applies regardless of VCC voltage.

How does the RT pin on the LTC2960HTS8-1#TRMPBF affect reset timing behavior?

The RT pin on the LTC2960HTS8-1#TRMPBF selects the reset timeout period: tied to GND yields 15ms, tied to VCC yields 200ms. This timeout begins after the ADJ input rises above threshold (or MR returns high) and delays RST release to ensure stable supply recovery. The RT pin is specific to LTC2960-1/-2 variants and is replaced by DVCC in -3/-4 versions.

Can the LTC2960HTS8-1#TRMPBF be used with a 1.8V logic supply for its RST and OUT outputs?

Yes - the RST and OUT outputs of the LTC2960HTS8-1#TRMPBF are 36V-tolerant open-drain pins. To interface with a 1.8V MCU, connect external pull-up resistors from RST and OUT to the 1.8V rail. The outputs will sink current when active low and float high, enabling clean logic-level compatibility without level shifters or additional ICs.

What is the guaranteed minimum hysteresis for the ADJ input on the LTC2960HTS8-1#TRMPBF?

The ADJ input of the LTC2960HTS8-1#TRMPBF has a guaranteed minimum hysteresis of 8mV (typical 10mV, max 15mV) over temperature. This corresponds to ~2.5% of the 400mV internal reference and ensures noise immunity during slow-rising supply conditions. Hysteresis is inherent and requires no external components.

Does the LTC2960HTS8-1#TRMPBF support manual reset assertion during brown-out conditions?

Yes - the MR input of the LTC2960HTS8-1#TRMPBF remains functional down to VCC = 2.5V. When MR is pulled low, RST is forced low immediately, and remains low for the full selected reset timeout period (15ms or 200ms) after MR returns high - even if VCC is near its UVLO threshold. This ensures deterministic reset initiation during marginal supply conditions.
