Product details
Overview
LTC2960CTS8-2#TRPBF 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 systems. It features 850nA quiescent current, 2.5V–36V supply range, ±1.5% threshold accuracy over –40°C to 125°C, and dual comparator inputs (ADJ + IN–) with 200ms fixed reset timeout. It is used in Li-ion multicell battery packs to trigger controlled shutdown before deep discharge.
For engineers reviewing the LTC2960CTS8-2#TRPBF datasheet, LTC2960CTS8-2#TRPBF pinout, LTC2960CTS8-2#TRPBF application, or LTC2960CTS8-2#TRPBF equivalent, key selection criteria include its 36V open-drain RST/OUT outputs, IN– input configuration for overvoltage detection, TSOT-23-8 package compatibility, and absence of RT pin (fixed 200ms timeout).
Technical Context
The LTC2960CTS8-2#TRPBF implements two independent comparators: one monitors ADJ for reset generation (threshold = 400mV ±6mV), and the second uses IN– for overvoltage detection (same 400mV reference). Its internal 400mV bandgap reference enables precise external resistor-divider programming of falling/rising thresholds across VCC up to 36V.
It operates with no external timing components: the 200ms reset timeout is factory-fixed (LTC2960-2 variant), and hysteresis is built-in (20mV on IN–, 10mV on ADJ). The 36V open-drain outputs support pull-up to voltages exceeding VCC, enabling direct interface with higher-voltage logic or MOSFET gate drivers without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V to 36V - supports direct connection to 12V/24V/36V battery rails without regulators |
| Quiescent Current | 850nA max at 36V - enables >10-year battery life in always-on monitoring applications |
| Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable reset assertion across automotive and industrial temperature ranges |
| IN– Threshold | 400mV ±6mV - sets precise overvoltage trip point when used with external divider |
| Reset Timeout | 200ms fixed - guarantees sufficient system stabilization time after power recovery |
| Output Type | 36V open-drain RST and OUT - allows flexible pull-up to any voltage ≤40V, including logic supplies higher than VCC |
| Input Leakage | ±1nA max at 85°C - permits use of high-value resistive dividers (>10MΩ) with <1% error |
Pinout & Package
Package: 8-lead TSOT-23 (0.65mm pitch, 2.9mm × 1.6mm footprint), RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Primary power supply input | Accepts 2.5V–36V; UVLO disables outputs below 1.85V; bypass with 0.1µF capacitor required |
| RT/DVCC | Not connected (NC) - pin repurposed as DVCC on -3/-4 variants only | Unused on LTC2960CTS8-2#TRPBF; must be left floating or tied to GND per layout guidelines |
| RST | Reset output | Open-drain, 36V-rated; pulls low when ADJ falls below threshold; released after 200ms timeout and hysteresis margin |
| OUT | Spare comparator output | Open-drain, 36V-rated; pulls low when IN– rises above threshold - configured for overvoltage detection |
| IN– | Inverting threshold input | Accepts 0–3.5V; used with resistor divider to set rising-voltage trip point (e.g., battery overvoltage) |
| ADJ | Reset threshold adjustment input | Accepts 0–3.5V; sets primary reset falling threshold via resistor divider from monitored rail |
| MR | Manual reset input | Logic-low active; forces RST low for full 200ms timeout upon release; internal 1µA pull-up |
| GND | Ground reference | System ground return for all analog and digital functions; connect directly to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|

| Factory-fixed 200ms timeout | Removes timing capacitor and associated board area, improving reliability and reducing BOM count |
| –40°C to 125°C operation | Qualified for under-hood automotive, industrial, and extended-temperature embedded applications |

FAQ
What is the reset timeout period for LTC2960CTS8-2#TRPBF?
The LTC2960CTS8-2#TRPBF has a fixed 200ms reset timeout period, as defined by its LTC2960-2 variant designation. This timeout begins after the ADJ input rises above its threshold plus hysteresis and continues until RST is released high. No external components or pin configuration are required to set this delay.
How does the IN– input function in LTC2960CTS8-2#TRPBF?
In the LTC2960CTS8-2#TRPBF, the IN– input serves as an inverting comparator threshold for overvoltage detection. When the voltage at IN– rises above 400mV, the OUT pin pulls low. This enables precise rising-threshold monitoring - for example, detecting battery overvoltage - using an external resistor divider from the monitored rail to GND.
Can LTC2960CTS8-2#TRPBF drive a 5V logic input directly?
Yes. The LTC2960CTS8-2#TRPBF features 36V open-drain RST and OUT outputs. To interface with a 5V logic input, connect a pull-up resistor from the output to the 5V rail. The output will sink current when active low and float (allowing pull-up) when inactive - fully compatible with standard CMOS/TTL inputs.
What is the maximum input voltage allowed on the ADJ and IN– pins of LTC2960CTS8-2#TRPBF?
The absolute maximum voltage on ADJ and IN– pins of LTC2960CTS8-2#TRPBF is 3.5V, as specified in the Absolute Maximum Ratings table. Exceeding this risks permanent damage. When monitoring higher-voltage rails (e.g., 12V, 24V), a resistor divider must scale the voltage to ≤3.5V at these inputs while maintaining <1nA leakage error.
Is LTC2960CTS8-2#TRPBF suitable for automotive under-hood applications?
Yes. The LTC2960CTS8-2#TRPBF is rated for operation from –40°C to 125°C (H-grade temperature range) and supports supply voltages up to 36V - meeting key requirements for under-hood automotive environments. Its 850nA quiescent current also complies with stringent ISO 16750-2 standby current limits.
