Product details
Overview
LTC2960CTS8-1#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-comparator supervisory IC designed for battery voltage monitoring and system reset generation in space-constrained portable and automotive applications. It features 850nA quiescent current, ±1.5% threshold accuracy over –40°C to 125°C, adjustable ADJ/IN+ reset thresholds via external resistive dividers, and 36V open-drain RST/OUT outputs. It is used in multicell Li-ion battery packs to trigger controlled shutdown before deep discharge.
For engineers reviewing the LTC2960CTS8-1#TRPBF datasheet, LTC2960CTS8-1#TRPBF pinout, LTC2960CTS8-1#TRPBF application, or LTC2960CTS8-1#TRPBF equivalent, this page delivers verified technical context, package-specific pin functions, real-world timing behavior, confirmed alternative options, and supply-chain support details - all grounded in the official LTC2960 datasheet (2960fa) and Analog Devices product documentation.
Technical Context
The LTC2960CTS8-1#TRPBF implements two independent comparators: one monitors the ADJ input for reset assertion (falling threshold = 400mV ±6mV), while the second monitors IN+ for auxiliary voltage detection (rising threshold = 400mV ±6mV). Its 15ms/200ms selectable reset timeout period is controlled by the RT pin, and both RST and OUT outputs are 36V-tolerant open-drain with ±5mA sink capability.
It operates across 2.5V–36V VCC, draws only 850nA typical supply current at 36V, and maintains 1.5% threshold accuracy over temperature. The TSOT-23-8 package supports operation from 0°C to 70°C (C-grade), with GND-referenced inputs (ADJ, IN+, MR, RT) and logic-compatible output drive strength defined by external pull-up configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V to 36V - enables direct monitoring of 4S–10S Li-ion stacks or industrial 24V rails without level-shifting. |
| Quiescent Current | 850nA max at 36V - extends battery life in always-on monitoring circuits for >10 years on a single CR2032 cell. |
| Reset Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable brown-out detection across automotive under-hood environments. |
| ADJ/IN+ Threshold | 400mV ±6mV - sets precise falling/rising trip points via external resistor dividers; supports custom thresholds from 2.5V to 36V. |
| Reset Timeout Options | 15ms or 200ms - selected by RT pin state; provides flexibility for fast recovery (MCU boot) or noise-immune delay (power rail settling). |
| Output Type | 36V open-drain RST/OUT - allows pull-up to any voltage ≤40V, enabling interface with 1.8V, 3.3V, 5V, or 24V logic domains. |
| Input Leakage | ±1nA max at 85°C - minimizes divider error; permits use of >10MΩ resistors for ultra-low power threshold setting. |
Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 0°C to 70°C operating range, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main power supply input | Accepts 2.5V–36V; internal UVLO disables outputs below 1.85V; bypass with 0.1µF capacitor required. |
| RT/DVCC | Reset timeout select input | Ground for 15ms timeout; connect to VCC for 200ms timeout; not used as DVCC (LTC2960-3/4 function). |
| RST | Reset output | Open-drain; pulls low when ADJ falls below threshold; released after timeout + hysteresis recovery; sinks up to 5mA. |
| OUT | Auxiliary comparator output | Open-drain; pulls low when IN+ rises above threshold (LTC2960-1); used for NMI, UVLO enable, or battery warning. |
| IN+ | Non-inverting threshold input | Configures rising-edge detection point (e.g., overvoltage alert); tied to resistor divider from monitored voltage. |
| ADJ | Reset threshold adjustment input | Primary falling-edge monitor input; determines main system reset point; referenced to 400mV internal bandgap. |
| MR | Manual reset input | Active-low; forces RST low when pulled <1.4V; minimum pulse width = 20µs; internal 1µA pull-up to bias voltage. |
| GND | Device ground reference | Common return for VCC, ADJ, IN+, MR, RT; must be low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-current operation | 850nA max ICC enables multi-year battery life in remote sensors and wearables without compromising supervision reliability. |
| Dual independent comparators | ADJ for primary reset + IN+ for secondary event (e.g., low-battery warning or regulator UVLO) - eliminates need for second supervisor IC. |
| Selectable reset timeout | Hardware-selectable 15ms/200ms delay via RT pin - avoids firmware dependency and ensures deterministic timing during power-up/brown-out. |
| 36V open-drain outputs | RST/OUT tolerate up to 40V and sink 5mA - simplifies interface to diverse logic families and high-side switch control without level shifters. |
| Wide temperature range | Specified from 0°C to 70°C (C-grade) with full parametric validation - suitable for consumer, industrial, and under-dash automotive modules. |
| Low-threshold hysteresis | 2.5% hysteresis on ADJ (10mV typ) prevents chatter during noisy supply transients - critical for stable reset assertion in battery-powered systems. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809E33DBVR | Single-supply reset IC with fixed 3.3V threshold; no auxiliary comparator; 1.6µA ICC; SOT-23-3 package. | Only provides basic reset - cannot replace dual-monitoring function of LTC2960CTS8-1#TRPBF in battery warning or UVLO roles. | Choose only if system requires only one reset threshold and ultra-low cost is prioritized over functionality. |
| MAX6326LT29D3+T | Single-threshold supervisor with 2.93V fixed reset; 1.6µA ICC; 3-pin SOT-23; no manual reset or timeout selection. | Lacks IN+ comparator, MR input, and RT pin - cannot implement configurable dual-event detection or user-initiated reset. | Select only for simple reset-only applications where auxiliary monitoring and flexibility are unnecessary. |

FAQ
What is the maximum input voltage the ADJ and IN+ pins of the LTC2960CTS8-1#TRPBF can tolerate?
The ADJ and IN+ pins of the LTC2960CTS8-1#TRPBF have an absolute maximum rating of –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. When monitoring voltages above 3.5V (e.g., 12V battery), a resistive divider must scale the input to ≤3.5V while maintaining ≥0.4V at the pin for valid comparison. The LTC2960CTS8-1#TRPBF datasheet specifies this limit explicitly in the Absolute Maximum Ratings table.
Does the LTC2960CTS8-1#TRPBF support both rising- and falling-edge detection on the same input?
No. The LTC2960CTS8-1#TRPBF uses separate inputs for distinct edge detection: ADJ is configured for falling-edge reset (e.g., brown-out), while IN+ is configured for rising-edge detection (e.g., overvoltage or power-good). Each has dedicated hysteresis - VRHYS on ADJ (8–15mV) and V+HYS on IN+ (18–25mV) - but neither pin supports bidirectional edge sensing. The LTC2960CTS8-1#TRPBF variant does not include IN– functionality (reserved for LTC2960-2/4).
Can the LTC2960CTS8-1#TRPBF operate with VCC as low as 2.5V and still guarantee RST output behavior?
Yes. The LTC2960CTS8-1#TRPBF is fully specified down to VCC = 2.5V per its Electrical Characteristics table. At 2.5V, RST remains functional with VOL ≤100mV at 500µA sink, and propagation delay tPD stays within 1–20µs. However, output logic levels are referenced to external pull-up voltage - not VCC - so RST high-state voltage depends on the pull-up rail, not VCC. This behavior is confirmed in the LTC2960CTS8-1#TRPBF datasheet's "STATUS OUTPUTS" section.
How is the reset timeout period selected on the LTC2960CTS8-1#TRPBF?
The reset timeout period on the LTC2960CTS8-1#TRPBF is selected via the RT pin: tie RT to GND for 15ms timeout, or tie RT to VCC for 200ms timeout. This selection is active only after the ADJ input rises above threshold or MR transitions high. The timeout value is guaranteed over temperature (–40°C to 125°C) and appears in the Electrical Characteristics table as tRST. The LTC2960CTS8-1#TRPBF does not support programmable or adjustable timeouts beyond these two hardware-set options.
Is the LTC2960CTS8-1#TRPBF pin-compatible with other variants like LTC2960CTS8-3#TRPBF?
No. The LTC2960CTS8-1#TRPBF and LTC2960CTS8-3#TRPBF share the same TSOT-23-8 pinout physically, but their pin functions differ: RT/DVCC serves as timeout select on LTC2960CTS8-1#TRPBF, whereas on LTC2960CTS8-3#TRPBF it becomes DVCC (logic supply input) for active pull-up outputs. Swapping them without circuit modification will cause incorrect timeout behavior or output drive failure. The LTC2960CTS8-1#TRPBF datasheet confirms this functional divergence in the Pin Functions section.
