Product details
Overview
LTC2960CTS8-4#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery monitoring and system reset control in space-constrained portable and automotive applications. It features 850nA quiescent current, 36V VCC operating range, ±2mV ADJ/IN– threshold matching, 200ms fixed reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It monitors battery voltage via ADJ input and detects overvoltage conditions via IN– input in multicell Li-ion systems.
For engineers reviewing the LTC2960CTS8-4#TRMPBF datasheet, LTC2960CTS8-4#TRMPBF pinout, LTC2960CTS8-4#TRMPBF application, or LTC2960CTS8-4#TRMPBF equivalent, this page delivers verified technical context, exact pin functions, real-world timing behavior, and validated alternative options - all specific to the LTC2960-4 variant in TSOT-23 package with –40°C to 85°C temperature grade and active-pull-up output architecture.
Technical Context
The LTC2960CTS8-4#TRMPBF implements two independent comparators: one on ADJ (reset threshold) with 2.5% hysteresis and 200ms timeout delay, and a second on IN– (inverting input) configured for overvoltage detection with 5% hysteresis. Its internal 400mV reference enables precise external resistor-divider programming of thresholds across 2.5V–36V supply range.
Unlike LTC2960-1/2 variants, it replaces the RT pin with DVCC to support logic-level programmable output swing (1.6V–5.5V), enabling direct interface with low-voltage microcontrollers without external pull-ups. GND-tied DVCC reconfigures RST/OUT as open-drain outputs, providing design flexibility for mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.5V to 36V - supports direct connection to 12V/24V automotive rails and multicell battery stacks without external regulators. |
| Quiescent Current (ICC) | 850nA max at 36V and –40°C to 85°C - enables >10-year battery life in coin-cell–powered security sensors. |
| ADJ Threshold Accuracy | ±1.5% over temperature - ensures reliable reset assertion across industrial temperature range without calibration. |
| IN– Threshold Hysteresis | 20mV (typ), 25mV (max) - prevents chatter during slow-rising overvoltage events like load dump transients. |
| Reset Timeout Period | Fixed 200ms - guarantees sufficient processor initialization time after power recovery before releasing RST high. |
| DVCC Operating Range | 1.6V to 5.5V - allows RST/OUT logic-high level to match 1.8V, 3.3V, or 5V MCU I/O domains without level shifters. |
| Input Leakage (ITH) | ±0.1nA at 420mV, –40°C to 85°C - permits use of >10MΩ resistor dividers with <0.1% error in high-impedance battery sensing. |
Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 2.9mm × 1.6mm footprint, exposed pad optional, rated for –40°C to 85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main power supply input | Accepts 2.5V–36V; UVLO disables outputs below 1.85V; bypass with 0.1µF capacitor required. |
| DVCC | Logic supply reference for RST/OUT | Defines high-state voltage of RST/OUT (1.6V–5.5V); grounding converts outputs to open-drain mode. |
| RST | Reset output | Active-low open-drain or active-pull-up (DVCC-referenced); asserts low when ADJ falls below threshold. |
| OUT | Spare comparator output | Active-low open-drain or active-pull-up; asserts low when IN– rises above programmed overvoltage threshold. |
| IN– | Inverting voltage monitor input | Configured with resistor divider to detect overvoltage; threshold = 400mV × (1 + R1/R2). |
| ADJ | Reset threshold adjustment input | Primary supervision input; falling threshold = 400mV × (1 + R1/R2); hysteresis = 2.5% of threshold. |
| MR | Manual reset input | Pulled low externally to force RST low; releases after 200ms timeout; internal 1µA pull-up simplifies switch interface. |
| GND | Device ground reference | Common return for VCC, DVCC, and all inputs; must be low-impedance path to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-current operation | 850nA ICC enables >10-year runtime on CR2032 coin cell in always-on battery monitors. |
| Dual independent comparators | ADJ for undervoltage reset + IN– for overvoltage detection - eliminates need for separate UVLO/OVLO ICs. |
| Configurable output drive | DVCC pin selects between active-pull-up (low static power) or open-drain (36V-compatible) RST/OUT outputs. |
| High-accuracy threshold matching | ±2mV ADJ/IN– threshold matching ensures consistent trip points across both channels without trimming. |
| Robust manual reset interface | MR accepts 0–36V logic levels with 20µs minimum pulse width - compatible with pushbuttons and MCU GPIOs. |
| Wide temperature operation | Specified from –40°C to 85°C - suitable for under-hood automotive and industrial edge sensor deployments. |
Applications
| Battery Overvoltage Protection | Automotive Power-Rail Supervisor |
|---|---|
|
Use Scenario: Monitoring 3–4 series Li-ion packs (12.6V–16.8V) to prevent cell overcharge during fast charging. IC Role / Device Role / Timing Role: LTC2960CTS8-4#TRMPBF uses IN– input to trigger OUT low when pack voltage exceeds 14.2V; ADJ input asserts RST if voltage drops below 10.5V. Use Value: Dual-threshold detection enables single-IC protection against both overvoltage and undervoltage faults, reducing BOM count by one supervisor IC. |
Use Scenario: Supervising 12V battery rail in telematics control units subject to load dump transients up to 36V. IC Role / Device Role / Timing Role: LTC2960CTS8-4#TRMPBF monitors VCC directly; RST holds MCU in reset during brownout; OUT signals overvoltage to enable clamping circuitry. Use Value: 36V VCC rating and 200ms timeout eliminate need for external TVS or regulator, simplifying front-end protection design. |
| Portable Medical Device Reset | Industrial Sensor Node Low-Power Wake-Up |
|
Use Scenario: Ensuring reliable boot sequence in handheld ECG monitors powered by single Li-ion cell (3.0V–4.2V).

FAQ
What is the function of the DVCC pin on the LTC2960CTS8-4#TRMPBF?
The DVCC pin on the LTC2960CTS8-4#TRMPBF sets the logic-high voltage level for the RST and OUT outputs. When DVCC is connected to a 1.6V–5.5V supply, RST and OUT actively drive high to that voltage. If DVCC is grounded, both outputs become open-drain and require external pull-up resistors. This dual-mode capability eliminates level-shifting components in mixed-voltage systems.
How does the LTC2960CTS8-4#TRMPBF differ from the LTC2960-1 variant?
The LTC2960CTS8-4#TRMPBF uses an IN– input for overvoltage detection and replaces the RT pin with DVCC to provide fixed 200ms reset timeout and logic-level configurable outputs. In contrast, LTC2960-1 uses IN+ for undervoltage detection and includes an RT pin to select between 15ms or 200ms timeout, with 36V open-drain outputs. The pinout, functionality, and application intent are not interchangeable.
Can the LTC2960CTS8-4#TRMPBF monitor voltages above 36V?
No - the absolute maximum VCC rating is 40V, and the ADJ/IN– inputs are limited to 3.5V. To monitor higher voltages (e.g., 60V battery stacks), external resistor dividers must scale the input so that the voltage at ADJ or IN– never exceeds 3.5V. For example, a 15:1 divider allows monitoring up to 52.5V while keeping the input within spec at 3.5V.
What is the minimum pulse width the MR input can detect on the LTC2960CTS8-4#TRMPBF?
The MR input on the LTC2960CTS8-4#TRMPBF requires a minimum pulse width of 20µs to reliably trigger a reset event. This specification is guaranteed over the full –40°C to 85°C temperature range and ensures compatibility with fast GPIO toggling or mechanical switch bounce filtering circuits without false triggering.
Does the LTC2960CTS8-4#TRMPBF support hot-swap or load-dump transient immunity?
The LTC2960CTS8-4#TRMPBF withstands 40V transients on VCC per Absolute Maximum Ratings, but sustained transients above 36V require external protection. Recommended solutions include a series current-limiting resistor (e.g., 143kΩ) plus a 30V Zener diode at the VCC input - as documented in Linear's Application Note 2960 F07 - to absorb energy while preserving nanoscale quiescent current performance.
