Product details
Overview
LTC2960IDC-2#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-comparator supervisor IC designed for battery voltage monitoring and system reset control in multicell Li-ion, automotive, and industrial power rails. It features 850nA quiescent current, ±1.5% threshold accuracy over –40°C to +85°C, adjustable ADJ/IN– reset thresholds via external resistive dividers, and 36V open-drain RST/OUT outputs. It is used in portable medical devices to detect low-battery conditions before deep discharge.
For engineers reviewing the LTC2960IDC-2#TRPBF datasheet, LTC2960IDC-2#TRPBF pinout, LTC2960IDC-2#TRPBF application, or LTC2960IDC-2#TRPBF equivalent, key selection criteria include its IN– input architecture for overvoltage detection, 15ms/200ms selectable reset timeout, 36V open-drain output capability, and compatibility with wide-input DC/DC regulators in harsh environments.
Technical Context
The LTC2960IDC-2#TRPBF implements two independent comparators: one monitors the ADJ input for reset generation (with 2.5% hysteresis), while the second uses the IN– input to detect rising supply voltages - enabling overvoltage lockout functionality. Its RT pin selects between 15ms and 200ms reset timeout periods after threshold recovery.
It operates from 2.5V to 36V VCC, supports manual reset (MR) with 20µs minimum pulse width, and guarantees output low-state down to VCC = 1.2V. The 36V open-drain RST and OUT outputs interface directly with logic supplies up to 36V without level-shifting, making it suitable for direct connection to gate drivers or high-side switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V to 36V - powers device directly from battery or unregulated rail without LDO |
| Quiescent Current | 850nA max at 36V - enables >10-year battery life in always-on monitoring applications |
| Reset Threshold Accuracy | ±1.5% over –40°C to +85°C - ensures reliable brown-out detection across automotive temperature range |
| IN– Input Threshold | 400mV nominal - sets overvoltage trip point via external resistor divider on monitored rail |
| Reset Timeout Options | 15ms or 200ms (RT pin-selectable) - provides flexibility for fast recovery or noise-immune delay |
| Output Type | 36V open-drain RST and OUT - drives pull-up to any voltage ≤36V, compatible with MOSFET gates and optocouplers |
| Input Leakage (ADJ/IN–) | ±1nA max at 85°C - allows use of >10MΩ resistor dividers with <0.1% error |
Pinout & Package
Package: 8-lead (2mm × 2mm) plastic DFN (DC8), exposed pad (optional GND connection), rated for –40°C to +85°C operating ambient.
| 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 |
| RT | Reset timeout select | Tie to GND for 15ms timeout; tie to VCC for 200ms timeout - no internal pull-up/pull-down |
| RST | Reset output | 36V open-drain; pulled low when ADJ falls below threshold; released after timeout and hysteresis margin |
| OUT | Spare comparator output | 36V open-drain; pulled low when IN– rises above threshold - used for overvoltage detection or UVLO enable |
| IN– | Inverting threshold input | Configures rising-voltage trip point (e.g., battery overvoltage); referenced to 400mV internal reference |
| ADJ | Reset threshold adjustment | Configures falling-voltage reset point (e.g., low-battery cutoff); referenced to 400mV internal reference |
| MR | Manual reset input | Active-low; forces RST low when asserted; 20µs minimum pulse width; internal 1µA pull-up |
| GND | Device ground | Reference for all inputs/outputs; exposed pad may be connected to PCB GND for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Nano-power operation | 850nA ICC enables multi-year battery life in remote sensors and wearables |
| Dual-threshold supervision | Independent ADJ (falling) and IN– (rising) inputs support both undervoltage and overvoltage monitoring |
| 36V open-drain outputs | RST and OUT drive external pull-ups up to 36V - eliminates need for level shifters in high-voltage systems |
| Selectable reset timeout | RT pin chooses 15ms (fast response) or 200ms (noise immunity) - no external timing components required |
| Wide temperature range | –40°C to +85°C operation certified for automotive cabin and industrial edge environments |
| Low-input leakage | ±1nA max at 85°C allows high-impedance resistor networks (>10MΩ) with minimal threshold error |
Applications

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-channel, fixed 3.3V reset; 1.6µA ICC; SOT-23-3 package; no IN– input or timeout selection | Only supports basic undervoltage reset; cannot perform overvoltage detection or dual-threshold monitoring | Choose only for simple, low-cost single-threshold reset where dual supervision is unnecessary |
| MAX6326LT29D2+T | Single-supply, 2.93V fixed reset; 1.2µA ICC; 6-pin SOT-23; no adjustable thresholds or IN– input | Lacks resistor-programmable thresholds and dual-comparator architecture; no overvoltage capability | Select when fixed-threshold reset suffices and board space is extremely constrained (6-pin footprint) |
Compared with TLV809E33DBVR and MAX6326LT29D2+T, the LTC2960IDC-2#TRPBF uniquely delivers dual-threshold (ADJ + IN–), 36V open-drain outputs, and selectable reset timeout in a compact DFN - enabling integrated overvoltage/undervoltage protection without external logic or timing components.

FAQ
What is the function of the IN– input on the LTC2960IDC-2#TRPBF?
The IN– input on the LTC2960IDC-2#TRPBF serves as an inverting threshold comparator that triggers the OUT output when the monitored voltage rises above the programmed threshold (e.g., for overvoltage detection). It references the internal 400mV bandgap, and its hysteresis is 20mV (5% of threshold), ensuring clean transitions during noisy supply conditions. This distinguishes the LTC2960IDC-2#TRPBF from variants with IN+ inputs.
How does the RT pin affect reset behavior in the LTC2960IDC-2#TRPBF?
The RT pin on the LTC2960IDC-2#TRPBF selects the reset timeout period: tying RT to GND configures a 15ms delay, while tying RT to VCC selects 200ms. This timeout determines how long RST remains low after the ADJ input recovers above threshold. The LTC2960IDC-2#TRPBF does not include internal pull resistors on RT, so external connection is mandatory for defined behavior.
Can the LTC2960IDC-2#TRPBF operate with VCC below 2.5V?
No - the LTC2960IDC-2#TRPBF has a specified minimum VCC of 2.5V per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 2.5V is not guaranteed; outputs may become undefined below VCC = 1.2V, and the internal reference and comparators cease functional operation. For sub-2.5V systems, alternative supervisors such as the LTC2906 should be considered.
What is the maximum voltage the RST and OUT pins can tolerate on the LTC2960IDC-2#TRPBF?
The RST and OUT pins on the LTC2960IDC-2#TRPBF are rated for up to 40V absolute maximum (per Absolute Maximum Ratings), and their open-drain structure allows safe interfacing with pull-up voltages up to 36V in normal operation. This makes the LTC2960IDC-2#TRPBF suitable for direct connection to high-side N-channel MOSFET gates or optocoupler LEDs without additional protection circuitry.
Is the LTC2960IDC-2#TRPBF pin-compatible with other LTC2960 variants?
Yes - all LTC2960 variants (including LTC2960IDC-1#TRPBF, LTC2960IDC-3#TRPBF, and LTC2960IDC-4#TRPBF) share identical 8-lead DFN (DC8) pinouts and footprints. However, functional differences exist: LTC2960IDC-2#TRPBF uses IN– and RT, while LTC2960IDC-3#TRPBF replaces RT with DVCC and uses IN+, so direct substitution requires schematic review for input configuration and output drive style.
