Analog Devices Inc. LTC2960IDC-4#TRMPBF

Overview

LTC2960IDC-4#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery and regulator monitoring in harsh environments. It features ADJ/IN– input configuration, fixed 200ms reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current at 36V, and operation from –40°C to +85°C. It is used in automotive battery disconnect circuits and portable equipment brown-out protection.

For engineers reviewing the LTC2960IDC-4#TRMPBF datasheet, LTC2960IDC-4#TRMPBF pinout, LTC2960IDC-4#TRMPBF application, or LTC2960IDC-4#TRMPBF equivalent, key selection criteria include its IN– comparator polarity, DVCC-referenced push-pull outputs, 200ms fixed timeout, ±2mV ADJ/IN– threshold matching, and compatibility with 1.6V–5.5V logic supplies.

Technical Context

The LTC2960IDC-4#TRMPBF implements two independent comparators: one monitors the ADJ input against a precise 400mV internal reference to generate RST, while the second compares the monitored voltage against the IN– input using the same reference to drive OUT. Its architecture supports both undervoltage and overvoltage detection via IN– polarity, enabling dual-fault monitoring in single-supply systems.

It uses an internal 400mV bandgap reference with 1.5% max accuracy over temperature, 20mV built-in hysteresis on IN–, and 10mV hysteresis on ADJ. The DVCC pin enables logic-level programmability of RST/OUT swing (1.6V–5.5V), eliminating external pull-ups and reducing static power-critical for battery longevity in always-on applications.

FAQ

What is the function of the DVCC pin on the LTC2960IDC-4#TRMPBF?

The DVCC pin on the LTC2960IDC-4#TRMPBF sets the logic-high voltage level for the RST and OUT outputs. When connected to a 1.6V–5.5V supply, it enables active pull-up (push-pull) operation, eliminating external pull-up resistors. Grounding DVCC reconfigures RST/OUT as open-drain outputs - providing interface flexibility across diverse logic families without redesigning the PCB.

How does the IN– input polarity affect system monitoring in the LTC2960IDC-4#TRMPBF?

The IN– input polarity in the LTC2960IDC-4#TRMPBF means the OUT output goes low when the monitored voltage *rises above* the configured threshold - enabling overvoltage detection. This complements the ADJ input's undervoltage function, allowing a single LTC2960IDC-4#TRMPBF to monitor both battery overcharge and deep discharge conditions in Li-ion protection circuits.

Can the LTC2960IDC-4#TRMPBF operate with a 1.8V logic supply?

Yes. The LTC2960IDC-4#TRMPBF supports DVCC from 1.6V to 5.5V. When DVCC = 1.8V, the RST and OUT outputs drive high to ~1.8V (with ±50nA leakage), ensuring clean interfacing with 1.8V microcontrollers. The internal 400mV reference remains stable regardless of DVCC value, preserving threshold accuracy.

What is the maximum input voltage allowed on the ADJ, IN+, or IN– pins of the LTC2960IDC-4#TRMPBF?

The absolute maximum voltage on ADJ, IN+, or IN– is –0.3V to +3.5V per the datasheet. Exceeding +3.5V risks permanent damage. To monitor higher voltages (e.g., 36V battery), external resistor dividers must scale the input so the pin voltage stays within this range - for example, a 100:1 divider limits 36V to 360mV at the pin.

Is the 200ms reset timeout period adjustable on the LTC2960IDC-4#TRMPBF?

No. The LTC2960IDC-4#TRMPBF has a fixed 200ms reset timeout period. Unlike the LTC2960-1/-2 variants that use the RT pin to select between 15ms and 200ms, the LTC2960-4 variant replaces RT with DVCC and permanently configures the timeout to 200ms - simplifying layout and eliminating timing uncertainty due to RT pin noise or floating states.
