Analog Devices Inc. LTC2960IDC-4

Overview

LTC2960IDC-4 from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for battery monitoring and power sequencing in harsh environments. It features ADJ/IN– dual-threshold monitoring, 200ms fixed reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current, and operation from 2.5V to 36V supply - ideal for multicell Li-ion battery packs and automotive brown-out detection.

For engineers reviewing the LTC2960IDC-4 datasheet, LTC2960IDC-4 pinout, LTC2960IDC-4 application, or LTC2960IDC-4 equivalent, key selection criteria include its IN– input configuration for overvoltage detection, DVCC-referenced push-pull outputs, –40°C to 85°C industrial temperature range, and compatibility with 1.6V–5.5V logic interfaces without external pull-ups.

Technical Context

The LTC2960IDC-4 implements two independent comparators: one on the ADJ pin (reset threshold, 400mV ±6mV typical) and one on the IN– pin (spare threshold, same reference), both with built-in hysteresis (V–HYS = 20mV typ). Its internal 200ms reset timeout timer activates after ADJ rises above threshold or MR releases, ensuring stable reset assertion during supply settling.

Unlike LTC2960-1/2 variants, it replaces the RT pin with DVCC to enable logic-level-controlled active pull-up outputs - RST and OUT drive to DVCC when high, eliminating external pull-up resistors and reducing static power. GND-referenced DVCC reconfigures outputs as open-drain for 36V-compatible interfacing.

FAQ

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

The DVCC pin on the LTC2960IDC-4 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 configures both outputs as 36V-tolerant open-drain. This dual-mode capability makes the LTC2960IDC-4 adaptable to diverse logic families without redesign.

How does the LTC2960IDC-4 differ from the LTC2960-2 variant?

The LTC2960IDC-4 is the industrial-grade (–40°C to +85°C), DFN-packaged version of the LTC2960-4 variant - not LTC2960-2. LTC2960-2 uses RT for timeout selection and open-drain outputs; LTC2960IDC-4 uses DVCC for logic-referenced outputs and has fixed 200ms timeout. The "IDC" prefix confirms industrial temp and DFN package; "-4" suffix confirms IN–/DVCC/200ms configuration.

Can the LTC2960IDC-4 monitor voltages above 36V?

No - the absolute maximum VCC rating is 40V, but continuous operation is limited to 36V. To monitor higher voltages (e.g., 60V bus), use an external resistive divider to scale the input to ≤36V at VCC, or add transient protection (e.g., Zener clamp + series resistor) as shown in Linear's Application Note 2960 F07. The ADJ/IN– inputs themselves are rated only to 3.5V and must always be driven via dividers.

What is the purpose of the IN– input on the LTC2960IDC-4?

The IN– input on the LTC2960IDC-4 enables overvoltage detection: OUT asserts low when the voltage at IN– rises above the 400mV internal reference. This is distinct from the ADJ input (used for undervoltage/brown-out reset) and allows single-chip dual-threshold monitoring - e.g., detecting both battery overcharge (IN–) and discharge cutoff (ADJ) in portable equipment.

Does the LTC2960IDC-4 require external components for basic operation?

Yes - a 0.1µF ceramic capacitor is required between VCC and GND for stability. External resistor dividers are mandatory to set ADJ and IN– thresholds (no internal scaling). No timing capacitors or pull-up resistors are needed due to the integrated 200ms timeout and DVCC-referenced outputs - significantly reducing BOM versus discrete supervisor solutions.
