Product details
Overview
LTC2960HTS8-4#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery and regulator monitoring in harsh environments. It features ADJ/IN– input configuration, fixed 200ms reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current at 36V, and operation from –40°C to 125°C. It is used in automotive battery disconnect circuits and deep-discharge protection systems.
For engineers reviewing the LTC2960HTS8-4#TRPBF datasheet, LTC2960HTS8-4#TRPBF pinout, LTC2960HTS8-4#TRPBF application, or LTC2960HTS8-4#TRPBF equivalent, key selection criteria include its IN– comparator polarity, DVCC-referenced active pull-up outputs, 200ms fixed timeout, ±2mV threshold matching, and TSOT-23-8 package compatibility with high-temp automotive designs.
Technical Context
The LTC2960HTS8-4#TRPBF implements two independent comparators: one on ADJ (reset threshold) with 2.5% hysteresis and a second on IN– (inverting input) for overvoltage detection. Its internal 400mV reference enables precise external resistor-divider programming of thresholds up to 36V.
It uses a dedicated DVCC pin (1.6V–5.5V) to define logic-high output levels for both RST and OUT, enabling direct interfacing with low-voltage microcontrollers while operating from a high-voltage VCC supply. The device guarantees valid outputs down to VCC = 1.2V and includes manual reset (MR) with 20µs minimum pulse width detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V to 36V - supports direct connection to multicell Li-ion, 12V/24V automotive, and industrial power rails without external regulators. |
| Quiescent Current | 850nA max at 36V/125°C - enables multi-year battery life in always-on monitoring applications such as security sensors and telematics. |
| Reset Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable brown-out detection across full automotive temperature range without calibration. |
| IN– Threshold Hysteresis | 18–25mV (5% of 400mV reference) - prevents chatter during slow-rising/falling supply transients in battery charge/discharge cycles. |
| Reset Timeout | Fixed 200ms - provides sufficient system initialization time after power recovery before releasing processor reset. |
| DVCC Range | 1.6V to 5.5V - allows RST/OUT logic-high levels to match MCU I/O voltage (e.g., 1.8V, 3.3V), eliminating level-shifters. |
| Input Leakage | ±0.1nA at 420mV, –40°C to 85°C - permits use of >10MΩ resistor dividers with <0.1% error, reducing power loss in high-impedance sensing. |
Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 3.0mm × 1.7mm × 0.9mm, –40°C to 125°C operating range, exposed pad optional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main power supply input | Accepts 2.5V–36V; powers internal circuitry and enables UVLO shutdown below 1.85V; bypass with 0.1µF capacitor required. |
| DVCC | Logic supply reference | Sets RST/OUT high-level voltage (0.7×DVCC min); grounding converts outputs to open-drain mode; must be 1.6V–5.5V when active. |
| RST | Reset output | Active-low open-drain or active pull-up (DVCC-referenced); asserts when ADJ falls below threshold; released after 200ms timeout + hysteresis recovery. |
| OUT | Spare comparator output | Active-low open-drain or active pull-up; asserts when IN– rises above threshold (overvoltage monitor); released when IN– falls below threshold minus hysteresis. |
| IN– | Inverting voltage sense input | Configures second threshold via resistor divider to ground; used for overvoltage detection (e.g., battery overcharge, regulator overvoltage). |
| ADJ | Reset threshold adjustment input | Primary supervision input; tied to resistor divider to set falling reset threshold (e.g., 6.0V battery undervoltage cutoff). |
| MR | Manual reset input | Active-low; pulls RST low when asserted; requires ≥20µs pulse width; internally pulled up with 1µA current source. |
| GND | Ground reference | System ground return for all analog and digital functions; must be low-impedance path for accurate threshold sensing. |
Key Features
| Feature | Design Value |
|---|---|
| 850nA quiescent current at 36V | Enables >10-year battery life in coin-cell-powered IoT sensors and automotive event recorders without duty cycling. |
| IN– input polarity option | Supports overvoltage detection (e.g., Li-ion cell overcharge) without external inverting circuitry-reduces BOM count and layout area. |
| DVCC-referenced active pull-up outputs | Eliminates external pull-up resistors and associated static power loss; improves rise time vs. open-drain; simplifies interface to 1.8V/3.3V MCUs. |
| ±2mV ADJ-to-IN– threshold matching | Ensures consistent trip points between reset and overvoltage channels-critical for tight-margin battery management in EV subsystems. |
| 200ms fixed reset timeout | Guarantees sufficient time for microcontroller boot, flash initialization, and peripheral stabilization after power recovery. |
| –40°C to 125°C operating range | Validated for under-hood automotive, industrial motor drives, and outdoor energy storage systems without derating. |

FAQ
What is the function of the DVCC pin on the LTC2960HTS8-4#TRPBF?
The DVCC pin on the LTC2960HTS8-4#TRPBF sets the logic-high voltage level for both RST and OUT outputs. When DVCC is connected to a 1.6V–5.5V supply, outputs actively drive to DVCC; when grounded, outputs revert to open-drain mode requiring external pull-ups. This eliminates static current in active pull-up mode and enables direct interfacing with diverse MCU I/O voltages without level shifters.
How does the LTC2960HTS8-4#TRPBF differ from the LTC2960HTS8-2#TRPBF?
The LTC2960HTS8-4#TRPBF uses an IN– input for its spare comparator (enabling overvoltage detection), has a fixed 200ms reset timeout, and features active pull-up outputs controlled by DVCC. In contrast, the LTC2960HTS8-2#TRPBF also uses IN– but offers selectable 15ms/200ms timeout via RT pin and 36V open-drain outputs-making LTC2960HTS8-4#TRPBF better suited for low-power, DVCC-matched MCU interfaces in high-temp environments.
Can the LTC2960HTS8-4#TRPBF monitor voltages above 36V?
No-the LTC2960HTS8-4#TRPBF VCC absolute maximum rating is 40V, and its ADJ/IN– inputs are limited to 3.5V. To supervise higher voltages (e.g., 60V bus), external resistor dividers must scale the input to ≤3.5V while maintaining leakage-current error <0.1%. For transients >40V, a Zener clamp (e.g., BZX84C30) and series resistor (e.g., 143kΩ) are required per Linear Application Note 2960.
What is the minimum pulse width the MR input can detect on the LTC2960HTS8-4#TRPBF?
The MR input on the LTC2960HTS8-4#TRPBF reliably detects pulses as short as 20µs across the full –40°C to 125°C temperature range. This allows fast, software-triggered resets via GPIO without requiring debouncing hardware, supporting real-time fault recovery in safety-critical automotive and industrial control systems.
Does the LTC2960HTS8-4#TRPBF require external capacitors for stable operation?
Yes-the LTC2960HTS8-4#TRPBF requires a 0.1µF ceramic capacitor between VCC and GND, placed as close as possible to the pins, to suppress supply noise and ensure accurate threshold detection. A second 0.1µF capacitor is recommended between DVCC and GND when DVCC is actively driven. No timing or hysteresis capacitors are needed-the 200ms timeout and comparator hysteresis are fully internal.
