Analog Devices Inc. LTC2960ITS8-2#TRMPBF

Overview

LTC2960ITS8-2#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery monitoring and power-rail supervision in harsh environments. It features 850nA quiescent current, ±1.5% threshold accuracy over –40°C to +85°C, adjustable ADJ/IN– reset thresholds, 200ms fixed reset timeout, and 36V open-drain RST/OUT outputs. It is used in automotive battery disconnect circuits where precise undervoltage detection prevents deep discharge.

For engineers reviewing the LTC2960ITS8-2#TRMPBF datasheet, LTC2960ITS8-2#TRMPBF pinout, LTC2960ITS8-2#TRMPBF application, or LTC2960ITS8-2#TRMPBF equivalent, key selection criteria include its IN– input configuration, 36V open-drain output capability, –40°C to +85°C industrial temperature range, 200ms reset timeout, and compatibility with high-side battery sensing via external resistive dividers.

Technical Context

The LTC2960ITS8-2#TRMPBF implements dual-comparator architecture: one dedicated ADJ input for primary reset threshold detection and a second IN– input configured for inverting-mode voltage monitoring-triggering OUT low when the sensed voltage rises above threshold. Its internal 400mV reference enables precise threshold setting across wide supply ranges.

It operates from 2.5V to 36V VCC, supports manual reset (MR) with 20µs minimum pulse width, and guarantees output validity down to VCC ≥ 1.2V. The 200ms reset timeout is fixed (no RT pin), and both RST and OUT are 36V-tolerant open-drain outputs requiring external pull-ups-ideal for interfacing with higher-voltage logic or driving MOSFET gates directly.

FAQ

What is the function of the IN– input on the LTC2960ITS8-2#TRMPBF?

The IN– input on the LTC2960ITS8-2#TRMPBF is an inverting comparator input that asserts the OUT output low when the sensed voltage rises above the programmed threshold (e.g., detecting overvoltage). This enables direct implementation of overvoltage protection or charge-complete signaling without external inverters. Unlike the ADJ input-which triggers RST on falling voltage-the IN– input responds to rising conditions, making LTC2960ITS8-2#TRMPBF suitable for dual-direction monitoring in a single device.

Does the LTC2960ITS8-2#TRMPBF support manual reset functionality?

Yes, the LTC2960ITS8-2#TRMPBF includes a dedicated MR (Manual Reset) input that forces the RST output low when pulled below 0.4V. After release, RST remains low for the full 200ms reset timeout period before returning high-ensuring clean system reset even during brief power glitches. The MR pin draws only ±1µA leakage, allowing direct connection to push-button switches or logic-level signals without external buffering. This behavior is fully specified across the –40°C to +85°C operating range of LTC2960ITS8-2#TRMPBF.

What is the maximum voltage the RST and OUT pins can tolerate on the LTC2960ITS8-2#TRMPBF?

The RST and OUT pins on the LTC2960ITS8-2#TRMPBF are rated for 36V absolute maximum and operate as 36V-tolerant open-drain outputs. They can safely interface with pull-up voltages up to 36V-enabling direct control of high-side N-channel MOSFETs, SiC gate drivers, or legacy 24V logic systems. This specification is guaranteed across the full –40°C to +85°C temperature range and does not require external clamping diodes when used within datasheet limits.

Can the LTC2960ITS8-2#TRMPBF be used with a 3.3V logic supply?

No-the LTC2960ITS8-2#TRMPBF is a 36V open-drain variant (LTC2960-2 family) and does not include the DVCC pin required for active pull-up to 3.3V logic levels. To interface with 3.3V systems, an external pull-up resistor to 3.3V must be used on RST and OUT. The outputs will then swing from 0V to 3.3V, compatible with standard CMOS inputs. This configuration is explicitly validated in the LTC2960ITS8-2#TRMPBF datasheet and requires no additional level-shifting circuitry.

What is the purpose of the exposed pad on the TSOT-23 package of the LTC2960ITS8-2#TRMPBF?

The exposed pad on the TSOT-23 package of the LTC2960ITS8-2#TRMPBF is electrically unconnected and thermally optional-it may be left floating or soldered to a PCB thermal pad for improved heat dissipation. Unlike DFN variants, the TSOT-23 exposed pad has no internal bond wire connection and serves solely as a mechanical anchor and thermal enhancement. No electrical grounding or biasing is required, and omitting the pad connection does not affect LTC2960ITS8-2#TRMPBF functionality or reliability under normal operating conditions.
