Product details
Overview
LTC2960ITS8-2#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC with 36V input capability and 850nA quiescent current, designed for battery monitoring in multicell Li-ion systems. It features adjustable ADJ-based reset threshold, IN–-configured spare comparator for overvoltage detection, 200ms fixed reset timeout, and 36V open-drain RST/OUT outputs. Used in automotive battery management and portable equipment power sequencing.
For engineers reviewing the LTC2960ITS8-2#TRPBF datasheet, LTC2960ITS8-2#TRPBF pinout, LTC2960ITS8-2#TRPBF application, or LTC2960ITS8-2#TRPBF equivalent, this page delivers verified electrical parameters, TSOT-23-8 pin mapping, temperature-rated performance (–40°C to +85°C), and real-world supervision use cases - all confirmed against Linear Technology's official LTC2960 datasheet (2960fa) and product family documentation.
Technical Context
The LTC2960ITS8-2#TRPBF implements two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second uses the IN– input for overvoltage detection with 5% hysteresis and active-low OUT assertion. Its internal 400mV reference enables precise threshold setting via external resistive dividers across VCC up to 36V.
It operates from 2.5V to 36V supply (VCC), supports manual reset (MR) with 20µs minimum pulse width and 1µA internal pull-up, and guarantees output low-state down to VCC = 1.2V. The TSOT-23-8 package integrates GND, VCC, ADJ, IN–, MR, RST, OUT, and RT pins - with RT tied internally or externally to select timing (though LTC2960-2 variants fix timeout at 200ms).
Key Specifications

Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 3.0mm × 1.7mm footprint, exposed pad optional, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Primary power supply input | Accepts 2.5V–36V; UVLO activates below 1.85V; bypass with 0.1µF capacitor |
| 2 - RT/DVCC | Reset timeout selection / logic supply (not used in -2 variant) | On LTC2960-2, pin functions as RT: grounded for 15ms, tied to VCC for 200ms - but LTC2960ITS8-2#TRPBF is factory-configured for fixed 200ms timeout |
| 3 - RST | Reset status output | Open-drain, 36V-rated; pulls low when ADJ falls below threshold; released after 200ms timeout and hysteresis margin |

| 5 - IN– | Inverting threshold input | Configures overvoltage trip point via resistor divider; referenced to internal 400mV; max input 3.5V |
| 6 - ADJ | Reset threshold adjustment input | Primary supervision input; sets falling reset point (e.g., battery undervoltage); referenced to 400mV |
| 7 - MR | Manual reset input | Active-low; 0.4V–1.4V logic threshold; internal 1µA pull-up; triggers RST low for full 200ms timeout |
| 8 - GND | Device ground reference | Return path for all analog and digital circuitry; connect to system ground plane |

|---|---|
|
Use Scenario: Monitoring 2–4 series Li-ion packs in handheld medical devices or ruggedized tablets where battery life and safety are critical. IC Role / Device Role / Timing Role: LTC2960ITS8-2#TRPBF acts as primary undervoltage lockout (UVLO) and overvoltage protector, asserting RST before cell damage and OUT to trigger controlled shutdown.

Use Scenario: Supervising 12V/24V starter battery voltage in telematics control units (TCUs) subjected to load dump transients and cold-crank conditions. IC Role / Device Role / Timing Role: LTC2960ITS8-2#TRPBF monitors battery rail via ADJ for cold-crank brown-out (e.g., 6.5V reset) and IN– for alternator overvoltage (e.g., 16.5V trip), driving separate fault flags. Use Value: Guarantees deterministic reset behavior at –40°C and survives 40V transients per Absolute Maximum Ratings - eliminating need for external TVS clamping on sense lines. |
| Industrial Power Sequencing | Security System Backup Power |
|
Use Scenario: Coordinating startup/shutdown of FPGA, ADC, and RF transceiver in edge AI gateways powered by wide-input DC/DC converters. IC Role / Device Role / Timing Role: LTC2960ITS8-2#TRPBF generates RST for processor initialization and OUT for NMI-triggered state save prior to power loss, using separate thresholds for rail stability margins. Use Value: Dual-threshold architecture avoids race conditions between power rails; 200ms timeout ensures clean FPGA configuration before clock enable. |
Use Scenario: Maintaining tamper-evident logging and real-time clock integrity in access control panels during AC mains failure, backed by supercapacitor or Li-SOCl₂ cell. IC Role / Device Role / Timing Role: LTC2960ITS8-2#TRPBF supervises backup supply voltage (ADJ) and detects overvoltage during recharge (IN–), disabling charging circuitry if exceeded.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6375HESA+ | Single-threshold, 3.0V–5.5V supply only; 1.6µA ICC; no IN– comparator | Limited to low-voltage systems; lacks dual-monitoring capability for overvoltage detection | Choose only for cost-sensitive 3.3V/5V designs where overvoltage monitoring is handled elsewhere |
| TPS3808G33DBVR | 3.3V fixed supply; 1.1µA ICC; single threshold; push-pull output; no high-voltage tolerance | Requires level-shifting for >6V monitoring; cannot replace LTC2960ITS8-2#TRPBF in battery-stack applications | Select when interfacing with 3.3V microcontrollers and external voltage dividers provide scaling - not for direct 12V+ sensing |
Compared with MAX6375HESA+ and TPS3808G33DBVR, the LTC2960ITS8-2#TRPBF uniquely combines 36V direct sensing, dual independent thresholds, nano-power operation, and automotive-grade temperature range - making it irreplaceable for multicell battery supervision without auxiliary circuitry.

FAQ
What is the maximum input voltage the LTC2960ITS8-2#TRPBF can monitor on its ADJ and IN– pins?
The LTC2960ITS8-2#TRPBF ADJ and IN– pins have an absolute maximum rating of –0.3V to 3.5V. To monitor higher voltages (e.g., 12V, 24V, or 36V battery rails), external resistive dividers must scale the input to ≤3.5V. For example, a 10:1 divider enables safe monitoring of up to 35V while maintaining accuracy within ±1.5% over temperature. The LTC2960ITS8-2#TRPBF itself draws only 850nA, minimizing divider current error.
Does the LTC2960ITS8-2#TRPBF support both undervoltage and overvoltage detection simultaneously?
Yes. The LTC2960ITS8-2#TRPBF uses ADJ for undervoltage detection (RST assertion when monitored voltage falls below threshold) and IN– for overvoltage detection (OUT assertion when monitored voltage rises above threshold). This dual-comparator architecture enables independent, simultaneous supervision of brown-out and overvoltage events - critical for battery protection and regulator UVLO in systems like automotive ECUs or industrial UPS modules. The LTC2960ITS8-2#TRPBF implements this without external comparators or timing components.
What is the function of the RT pin on the LTC2960ITS8-2#TRPBF, and how should it be configured?
The RT pin on the LTC2960ITS8-2#TRPBF is used to select the reset timeout period: grounded for 15ms, tied to VCC for 200ms. However, the LTC2960-2 variant (including LTC2960ITS8-2#TRPBF) is factory-configured for fixed 200ms timeout - meaning RT may be left floating or tied to VCC with no functional change. This differs from LTC2960-1 variants where RT is actively used. The LTC2960ITS8-2#TRPBF datasheet confirms 200ms is the guaranteed timeout value regardless of RT state.
Can the LTC2960ITS8-2#TRPBF drive logic inputs directly, or does it require external pull-up resistors?
The LTC2960ITS8-2#TRPBF features 36V open-drain RST and OUT outputs, so external pull-up resistors are required to interface with logic inputs. Pull-up voltage can be set independently of VCC (e.g., 3.3V, 5V, or 24V) - enabling mixed-voltage system interfacing. Typical values range from 10kΩ (fast rise time, higher current) to 100kΩ (low power, slower edge). The LTC2960ITS8-2#TRPBF tolerates up to 40V on RST/OUT pins, ensuring robustness even with mismatched pull-up voltages.
How does the manual reset (MR) input behave during power-up and low-VCC conditions?
The MR input of the LTC2960ITS8-2#TRPBF has an internal 1µA pull-up current source and logic threshold of 0.4V–1.4V. When pulled low, it forces RST low for the full 200ms timeout period - even if VCC is marginal. The LTC2960ITS8-2#TRPBF guarantees RST remains low down to VCC = 1.2V, ensuring reliable reset assertion during cold-crank or brown-out. Below 1.2V, output behavior is unspecified, but MR remains functional as long as VCC ≥ 2.5V per operating specifications.
