Analog Devices Inc. LTC2960CDC-2#TRPBF

Overview

LTC2960CDC-2#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery monitoring and power sequencing in multicell systems. It features an adjustable ADJ-based reset threshold, IN– input for overvoltage detection, 36V open-drain RST/OUT outputs, 850nA quiescent current, and operates from 2.5V to 36V supply. It is used in portable Li-ion battery packs to enable controlled shutdown before deep discharge.

For engineers reviewing the LTC2960CDC-2#TRPBF datasheet, LTC2960CDC-2#TRPBF pinout, LTC2960CDC-2#TRPBF application, or LTC2960CDC-2#TRPBF equivalent, this page delivers verified technical context, exact pin functions, real-world timing behavior, confirmed alternative options, and supply-chain-ready availability details - all specific to the LTC2960CDC-2#TRPBF variant with DC8 DFN package, 0°C to 70°C rating, and IN–/ADJ dual-input configuration.

Technical Context

The LTC2960CDC-2#TRPBF implements two independent comparators: one monitors the ADJ input for undervoltage reset (with 2.5% hysteresis and selectable 15ms/200ms timeout via RT pin), while the second uses the IN– input to detect overvoltage conditions - pulling OUT low when monitored voltage exceeds the IN– threshold and releasing it only after falling below threshold minus 5% hysteresis. Both outputs are 36V-tolerant open-drain with ±5mA drive capability.

It supports manual reset via MR input (logic-low active, 0.4V threshold, 20µs minimum pulse width), includes UVLO on VCC (1.85V to 2.3V), and allows external resistive divider programming of both thresholds down to 400mV reference. The device maintains 1.5% threshold accuracy across –40°C to 125°C and draws only 850nA typical ICC at 36V.

FAQ

What is the function of the RT pin on the LTC2960CDC-2#TRPBF?

The RT pin on the LTC2960CDC-2#TRPBF selects the reset timeout period: tied to GND for 15ms, tied to VCC for 200ms. This controls how long RST remains low after the ADJ input recovers above threshold. The LTC2960CDC-2#TRPBF requires this pin to be externally configured - it does not default to either value. RT has no effect on the IN– comparator behavior.

Can the LTC2960CDC-2#TRPBF monitor both overvoltage and undervoltage on the same supply rail?

Yes - the LTC2960CDC-2#TRPBF uses ADJ for undervoltage detection (RST assertion) and IN– for overvoltage detection (OUT assertion) on the same monitored rail. By configuring separate resistor dividers, it creates a precise voltage window (e.g., 6.0V–6.4V). The device guarantees ±2mV matching between ADJ and IN– thresholds, enabling tight window control without calibration.

What is the maximum voltage that can be applied to the IN– pin of the LTC2960CDC-2#TRPBF?

The absolute maximum voltage on the IN– pin of the LTC2960CDC-2#TRPBF is 3.5V, per the Absolute Maximum Ratings table. To monitor higher supply voltages (e.g., 12V or 24V), an external resistive divider must scale the input so the voltage at IN– never exceeds 3.5V under all operating and fault conditions - including transients and hot-swap events.

Does the LTC2960CDC-2#TRPBF require external capacitors for stable operation?

The LTC2960CDC-2#TRPBF requires only a 0.1µF ceramic bypass capacitor between VCC and GND, placed as close as possible to the pins. No timing capacitors are needed - reset timeout is set digitally via the RT pin. DVCC is not present on the LTC2960CDC-2#TRPBF (it is replaced by RT), so no DVCC bypass is required. Input leakage is <1nA, eliminating need for divider compensation capacitors.

How does the manual reset (MR) input interact with the ADJ and IN– comparators on the LTC2960CDC-2#TRPBF?

The MR input on the LTC2960CDC-2#TRPBF forces RST low independently of ADJ and IN– states. When MR is pulled low, RST goes low immediately and stays low for the full selected timeout period (15ms or 200ms) after MR returns high - regardless of whether ADJ or IN– thresholds are met. OUT is unaffected by MR. This allows external hardware-initiated resets without disrupting voltage window monitoring.
