Analog Devices Inc. LTC2960CTS8-3#TRMPBF

Overview

LTC2960CTS8-3#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input 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, fixed 200ms reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It is used in Li-ion multicell battery packs to provide low-battery warning and regulated UVLO signaling.

For engineers reviewing the LTC2960CTS8-3#TRMPBF datasheet, LTC2960CTS8-3#TRMPBF pinout, LTC2960CTS8-3#TRMPBF application, or LTC2960CTS8-3#TRMPBF equivalent, this page delivers verified functional identity, TSOT-23 pin mapping, real-world timing behavior, confirmed comparator input polarity (ADJ/IN+), DVCC-referenced output logic configuration, and validated alternative options for battery supervision designs.

Technical Context

The LTC2960CTS8-3#TRMPBF implements dual-comparator supervision with one dedicated ADJ input for reset threshold detection and a second non-inverting IN+ input for auxiliary voltage monitoring. Its internal 400mV reference enables precise external resistor-divider programming of falling thresholds across both inputs, with built-in 20mV (5%) hysteresis on IN+ and 10mV (2.5%) on ADJ.

Unlike variants with RT pin selection, this part fixes the reset timeout at 200ms and replaces RT with DVCC - a dedicated logic supply input that sets RST/OUT high-level voltage (1.6V–5.5V) and enables active pull-up operation. Grounding DVCC reconfigures outputs as open-drain, supporting mixed-voltage system interfacing without external pull-ups.

FAQ

What is the exact reset timeout period for LTC2960CTS8-3#TRMPBF?

The LTC2960CTS8-3#TRMPBF has a fixed reset timeout period of 200ms, confirmed in the Option Table and Electrical Characteristics section (tRST = 140ms to 280ms, typical 200ms). This value is factory-set and cannot be adjusted via external pins - unlike LTC2960-1/-2 variants with RT pin selection. The timeout begins after the ADJ input rises above threshold and ends when RST transitions high, provided hysteresis recovery is complete.

Does LTC2960CTS8-3#TRMPBF support both ADJ and IN+ inputs simultaneously?

Yes, the LTC2960CTS8-3#TRMPBF fully supports concurrent use of ADJ and IN+ inputs: ADJ controls the RST output with 2.5% hysteresis, while IN+ controls the OUT output with 5% hysteresis. Both inputs share the same 400mV internal reference and can be configured using independent or shared resistor dividers. The datasheet confirms this dual-comparator architecture in the Block Diagram and Pin Functions sections.

Can LTC2960CTS8-3#TRMPBF drive 3.3V logic directly without level shifters?

Yes - when DVCC is connected to 3.3V, the RST and OUT outputs of LTC2960CTS8-3#TRMPBF actively drive to 3.3V (VOH = 0.7•DVCC min), making them fully compatible with standard 3.3V CMOS inputs. This eliminates external level shifters or pull-up resistors required by open-drain alternatives. The VOH specification and DVCC pin function are explicitly defined in the Electrical Characteristics table.

What is the maximum input voltage allowed on ADJ, IN+, or MR pins?

The absolute maximum rating for ADJ, IN+, and MR pins is –0.3V to 3.5V, as stated in the Absolute Maximum Ratings table. Exceeding 3.5V risks permanent damage. This limit applies regardless of VCC voltage. To monitor higher voltages (e.g., 12V battery), external resistor dividers must scale the signal to ≤3.5V at the pin - a requirement confirmed in the Applications Information section and Figure 1.

Is LTC2960CTS8-3#TRMPBF qualified for automotive temperature range?

No - the "CTS8" suffix indicates the Commercial temperature grade (0°C to 70°C), per the Order Information table. For automotive use, select the "HTS8" variant (e.g., LTC2960HTS8-3#TRMPBF), rated from –40°C to 125°C. The C-grade version lacks extended-temperature qualification and may not meet AEC-Q100 requirements for under-hood deployment.
