Product details
Overview
LTC2960ITS8-3#TRPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery and automotive power monitoring. 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 battery-powered systems to generate precise reset and low-battery warning signals.
For engineers reviewing the LTC2960ITS8-3#TRPBF datasheet, LTC2960ITS8-3#TRPBF pinout, LTC2960ITS8-3#TRPBF application, or LTC2960ITS8-3#TRPBF equivalent, key selection criteria include its 200ms fixed timeout, IN+/ADJ dual-threshold configuration, DVCC-referenced push-pull outputs, –40°C to 85°C industrial temperature grade, and TSOT-23-8 package compatibility with space-constrained portable and automotive designs.
Technical Context
The LTC2960ITS8-3#TRPBF integrates two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second monitors IN+ for configurable voltage status detection with 5% hysteresis. Its internal 400mV reference enables accurate threshold setting via external resistive dividers across wide input voltages.
Unlike variants with RT pin or open-drain outputs, this part replaces RT with DVCC to support logic-level output swing control (1.6V–5.5V), enabling direct interfacing with microcontrollers or FPGAs without external pull-ups. It guarantees RST/OUT low state down to VCC = 1.2V and supports manual reset activation via MR input with 20µs minimum pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V to 36V - supports direct connection to 12V/24V automotive rails and multicell Li-ion stacks without regulation. |
| Quiescent Current | 850nA max at 36V/85°C - enables multi-year battery life in always-on monitoring applications. |
| Reset Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable reset assertion across automotive temperature extremes. |
| ADJ/IN+ Threshold Matching | ±2mV max - allows tightly coupled dual-threshold monitoring (e.g., UVLO + low-battery warning) with minimal calibration error. |
| Reset Timeout | Fixed 200ms - provides sufficient system initialization time after power recovery without requiring external timing components. |
| DVCC Range | 1.6V to 5.5V - sets RST/OUT logic-high level independently of VCC, enabling seamless interface with 1.8V/3.3V/5V digital logic. |
| Input Leakage | ±0.1nA at 420mV, –40°C to 85°C - permits use of high-impedance resistor dividers (e.g., >10MΩ) with sub-1% error. |
Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 2.9mm × 1.6mm × 0.85mm, –40°C to 85°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Power source up to 36V; undervoltage lockout activates below 1.85V; bypass with 0.1µF capacitor required. |
| DVCC | Logic supply reference | Sets RST/OUT high-level voltage (1.6V–5.5V); grounding converts outputs to open-drain mode. |
| RST | Reset output | Active-pull-up output driven to DVCC when high; pulled low when ADJ falls below threshold; released after 200ms timeout. |
| OUT | Secondary status output | Active-pull-up output driven to DVCC when high; pulled low when IN+ falls below threshold; released after 5% hysteresis recovery. |
| IN+ | Non-inverting comparator input | Configures second monitoring threshold (e.g., low-battery warning); tied to resistive divider from monitored rail. |
| ADJ | Reset threshold adjustment input | Primary reset trigger point; threshold set by resistive divider; internal 400mV reference enables precise falling-edge detection. |
| MR | Manual reset input | Active-low input; forces RST low when asserted; releases after 200ms timeout; internal 1µA pull-up simplifies switch interface. |
| GND | Ground reference | Analog and digital ground common node; exposed pad not present in TSOT-23 package. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-power operation | 850nA ICC enables >10-year battery life in coin-cell–powered security sensors and IoT endpoints. |
| Dual independent comparators | ADJ for primary reset + IN+ for secondary event (e.g., low-battery interrupt) eliminates need for second supervisor IC. |
| DVCC-referenced outputs | Eliminates external pull-up resistors and associated static power loss; improves rise time vs open-drain alternatives. |
| 200ms fixed timeout | Guarantees stable reset release after brown-out recovery without external RC timing network or configuration pins. |
| –40°C to 85°C industrial grade | Validated performance across automotive cabin and industrial control environments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809E33DBVR | Single-input, fixed 3.3V reset; 1.6µA ICC; SOT-23-3; no DVCC or secondary comparator. | Only suitable for single-rail 3.3V systems; lacks dual-threshold capability and nano-power efficiency. | Select only if design requires minimal footprint and fixed threshold, and 850nA vs 1.6µA quiescent current is not critical. |
| MAX6375XR29+T | Single-input, adjustable threshold; 1.2µA ICC; 200ms timeout; open-drain outputs; SOT-23-5. | No DVCC or IN+ input; requires external pull-up resistors; higher supply current reduces battery life. | Choose when cost is prioritized over power efficiency and dual-monitoring capability is unnecessary. |
Compared with TLV809E33DBVR and MAX6375XR29+T, the LTC2960ITS8-3#TRPBF uniquely delivers dual-threshold supervision, 850nA operation, and DVCC-referenced push-pull outputs in an 8-pin TSOT-23-enabling compact, long-life, and functionally richer power monitoring where precision and flexibility matter.

FAQ
What is the operating temperature range of the LTC2960ITS8-3#TRPBF?
The LTC2960ITS8-3#TRPBF is rated for –40°C to +85°C ambient operation, making it suitable for industrial control panels and automotive cabin electronics. This grade is confirmed in the Order Information table under "LTC2960ITS8-3#TRPBF" with marking code LTFSD and specified temperature range.
Does the LTC2960ITS8-3#TRPBF support adjustable reset thresholds?
Yes, the LTC2960ITS8-3#TRPBF supports fully adjustable reset thresholds via external resistive dividers on the ADJ and IN+ pins. Its internal 400mV reference enables precise falling-edge detection; for example, a 6.0V reset threshold is achieved with a resistor ratio yielding 400mV at ADJ when the monitored rail is at 6.0V.
How does the DVCC pin affect the RST and OUT outputs of the LTC2960ITS8-3#TRPBF?
When DVCC is connected to a 1.6V–5.5V supply, RST and OUT drive actively to that voltage when high-eliminating external pull-up resistors. If DVCC is grounded, both outputs revert to open-drain mode and require external pull-ups. This dual-mode flexibility is documented in the Pin Functions section and Option Table.
Is the reset timeout period configurable on the LTC2960ITS8-3#TRPBF?
No-the LTC2960ITS8-3#TRPBF has a fixed 200ms reset timeout period, as confirmed in the Option Table and Electrical Characteristics (tRST = 140ms to 280ms, typical 200ms). Unlike LTC2960-1/-2 variants with RT pin, this part replaces RT with DVCC and does not support selectable timeout periods.
Can the LTC2960ITS8-3#TRPBF monitor two different voltage rails simultaneously?
Yes-the LTC2960ITS8-3#TRPBF monitors two independent voltage conditions: ADJ for primary reset and IN+ for secondary status (e.g., low-battery warning). Each input uses its own resistive divider, enabling simultaneous supervision of, for example, a 12V main rail and a 3.3V logic rail with separate thresholds and hysteresis.
