Analog Devices Inc. LTC2960IDC-3#TRPBF

Overview

LTC2960IDC-3#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-comparator voltage supervisor IC designed for battery and regulator monitoring in space-constrained systems. It features 850nA quiescent current, 2.5V–36V VCC operating range, ±2mV ADJ/IN+ threshold matching, 200ms fixed reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It is used in multicell Li-ion battery packs to generate precise low-battery and UVLO signals.

For engineers reviewing the LTC2960IDC-3#TRPBF datasheet, LTC2960IDC-3#TRPBF pinout, LTC2960IDC-3#TRPBF application, or LTC2960IDC-3#TRPBF equivalent, key selection criteria include its 200ms fixed timeout, IN+/ADJ input configuration, DVCC-referenced push-pull outputs, –40°C to 85°C industrial temperature grade, and compatibility with 1.6V–5.5V logic supplies.

Technical Context

The LTC2960IDC-3#TRPBF 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 inputs ADJ and IN+.

Unlike variants with RT pin or open-drain outputs, the LTC2960IDC-3#TRPBF replaces RT with DVCC - a dedicated logic supply pin that sets RST/OUT high-level voltage (0.7×DVCC min) and enables true push-pull operation. Grounding DVCC reconfigures outputs as open-drain, supporting mixed-voltage system interfacing.

FAQ

What is the function of the DVCC pin on the LTC2960IDC-3#TRPBF?

The DVCC pin on the LTC2960IDC-3#TRPBF serves as the logic supply reference for the RST and OUT outputs. When connected to 1.6V–5.5V, it enables active pull-up (push-pull) operation with VOH ≥ 0.7×DVCC. Grounding DVCC reconfigures both outputs as 36V-tolerant open-drain drivers, allowing flexible interface with diverse logic families. This dual-mode capability is unique to the LTC2960-3/LTC2960-4 variants and is not present in -1/-2 versions.

How does the LTC2960IDC-3#TRPBF differ from the LTC2960IDC-1#TRPBF?

The LTC2960IDC-3#TRPBF uses DVCC instead of RT and provides active pull-up RST/OUT outputs, whereas the LTC2960IDC-1#TRPBF has an RT pin to select between 15ms/200ms timeout and 36V open-drain outputs. The LTC2960IDC-3#TRPBF fixes the timeout at 200ms and eliminates the need for external pull-up resistors, reducing power dissipation and improving rise time. Both share identical ADJ/IN+ input architecture and temperature grade (–40°C to 85°C).

Can the LTC2960IDC-3#TRPBF monitor two different supply voltages simultaneously?

Yes, the LTC2960IDC-3#TRPBF can monitor two distinct supply voltages simultaneously: ADJ monitors one voltage (e.g., main system rail) for reset generation, while IN+ monitors a second voltage (e.g., backup battery or auxiliary rail) for status signaling. Each input uses its own resistive divider network. The device's ±2mV threshold matching and 1.5% accuracy ensure coordinated, correlated responses - critical for sequencing and fault isolation in multi-rail systems.

What is the minimum recommended decoupling capacitance for the VCC pin of the LTC2960IDC-3#TRPBF?

The minimum recommended decoupling capacitance for the VCC pin of the LTC2960IDC-3#TRPBF is 0.01µF ceramic, placed as close as possible to the pin with short traces. A 0.1µF capacitor is commonly used and recommended in all typical applications to suppress high-frequency noise and supply transients. The capacitor must have a voltage rating compatible with the maximum applied VCC (e.g., 50V for 36V operation), and X7R dielectric is preferred for stability across temperature.

Does the LTC2960IDC-3#TRPBF provide hysteresis on both comparator inputs?

Yes, the LTC2960IDC-3#TRPBF provides built-in hysteresis on both monitored inputs: 2.5% (≈10mV) on ADJ relative to its 400mV internal reference, and 5% (≈20mV) on IN+ relative to the same reference. This hysteresis prevents output chatter during slow-moving or noisy supply transitions. The hysteresis values are specified over the full –40°C to 85°C temperature range and do not require external components to implement.
