Product details
Overview
LTC2960CDC-3 from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery monitoring and power-rail supervision in space-constrained systems. It features 850nA quiescent current, 200ms fixed reset timeout, ADJ/IN+ dual-threshold inputs, and active pull-up RST/OUT outputs referenced to DVCC. It is used in battery-powered portable equipment to provide precise brown-out detection and controlled shutdown signaling.
For engineers reviewing the LTC2960CDC-3 datasheet, LTC2960CDC-3 pinout, LTC2960CDC-3 application, or LTC2960CDC-3 equivalent, key selection considerations include its 2.5V–36V VCC range, ±2mV ADJ/IN+ threshold matching, 1.5% max threshold accuracy over temperature, 2mm × 2mm DFN package, and DVCC-referenced logic-level outputs for mixed-supply interfacing.
Technical Context
The LTC2960CDC-3 integrates a precision 400mV internal reference with comparator-based supervision architecture. Its ADJ input sets the primary reset threshold via external resistive divider, while IN+ provides a second adjustable voltage monitor with 20mV hysteresis (5% of 400mV). The device uses an internal 200ms monostable timer to enforce reset hold time after threshold recovery.
Unlike LTC2960-1/-2 variants, the LTC2960CDC-3 replaces the RT pin with DVCC to enable active pull-up outputs - RST and OUT are driven to DVCC (1.6V–5.5V) when high, eliminating external pull-up resistors and reducing static power. Grounding DVCC reconfigures outputs as open-drain for 36V-compatible interfacing.
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 rails without external regulators. |
| Quiescent Current | 850nA max at 36V - enables >10-year battery life in always-on monitoring applications such as security sensors or IoT edge nodes. |
| Reset Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable power-up sequencing across automotive and industrial temperature extremes. |
| Reset Timeout | Fixed 200ms - guarantees sufficient system stabilization time before releasing microcontroller reset, preventing premature boot failures. |
| ADJ/IN+ Threshold Matching | ±2mV - allows tightly coupled dual-threshold monitoring (e.g., UVLO + low-battery warning) with minimal calibration error. |
| DVCC Range | 1.6V to 5.5V - permits direct interface with 1.8V, 3.3V, or 5V logic families without level-shifting circuitry. |
| Operating Temp | 0°C to 70°C - specified for commercial-grade embedded systems including portable medical devices and consumer electronics. |
Pinout & Package
Package: 8-lead (2mm × 2mm) plastic DFN (DC8), exposed pad optional for thermal relief or GND connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Power source for internal circuitry; UVLO triggers RST/OUT low if falls below 1.85V (rising) or 2.3V (falling). |
| DVCC | Logic supply reference | Sets high-state voltage of RST/OUT; grounding configures outputs as open-drain for 36V compatibility. |
| RST | Primary reset output | Active-pull-up to DVCC when high; pulled low when ADJ voltage drops below threshold + hysteresis. |
| OUT | Secondary status output | Active-pull-up to DVCC when high; pulled low when IN+ voltage drops below threshold + 20mV hysteresis. |
| IN+ | Non-inverting monitor input | Configures second threshold (e.g., low-battery warning); tied to resistive divider from monitored rail. |
| ADJ | Reset threshold adjustment | Primary supervision input; threshold set by external resistor divider to achieve custom falling reset point. |
| MR | Manual reset input | Pull low to force RST low; releases after 200ms timeout - used for hardware-initiated system reset or test mode entry. |
| GND | Device ground reference | Analog and digital return path; exposed pad may be connected to PCB GND for improved thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-power operation | 850nA max ICC enables multi-year battery life in remote sensors and wearables without compromising supervision reliability. |
| Dual independent thresholds | ADJ and IN+ inputs allow simultaneous monitoring of main supply (e.g., 6.4V UVLO) and auxiliary rail (e.g., 3.3V regulator output) using one IC. |
| Configurable output logic | DVCC pin enables seamless transition between active pull-up (low static power, fast rise) and open-drain (high-voltage compatibility) modes. |
| Integrated 200ms timer | Eliminates need for external RC timing components - reduces BOM count and layout area in compact designs. |
| Wide temperature accuracy | ±1.5% threshold error maintained from –40°C to 125°C, ensuring robust operation in automotive under-hood and industrial control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2960IDC-3#TRPBF | Same functionality and pinout, but rated for –40°C to 85°C industrial temperature range. | Required for extended-temperature deployments where ambient exceeds 70°C (e.g., enclosed industrial enclosures). | Select LTC2960IDC-3 when operating temperature must exceed 70°C; otherwise LTC2960CDC-3 is optimal for cost-sensitive commercial designs. |
| MAX6326UT29D3+T | Single-threshold supervisor (2.93V fixed), no IN+ input, 3µA ICC, SOT23-3 package. | Lacks dual-monitoring capability and nano-power efficiency; suitable only for basic reset-only use cases. | Choose MAX6326UT29D3+T only if dual-threshold monitoring and sub-1µA current are unnecessary - not a functional substitute for LTC2960CDC-3. |
Compared with LTC2960IDC-3#TRPBF, the LTC2960CDC-3 offers identical electrical performance at lower cost for commercial-temperature applications; compared with MAX6326UT29D3+T, it delivers dual-threshold supervision, 28× lower quiescent current, and configurable outputs - making it superior for battery-critical and feature-rich designs.

FAQ
What is the maximum input voltage the ADJ and IN+ pins of the LTC2960CDC-3 can tolerate?
The ADJ and IN+ pins of the LTC2960CDC-3 have an absolute maximum rating of –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. To monitor higher voltages (e.g., 12V or 24V rails), external resistive dividers must scale the input down to ≤3.5V while maintaining ≥0.4V at the pin for valid threshold detection. The LTC2960CDC-3 datasheet specifies that VIN must stay within this limit regardless of VCC level.
How does the DVCC pin affect the output behavior of the LTC2960CDC-3?
The DVCC pin defines the logic-high voltage level of both RST and OUT outputs in the LTC2960CDC-3. When DVCC is connected to a 1.6V–5.5V supply, outputs actively drive to that voltage. When DVCC is grounded, RST and OUT become open-drain and require external pull-up resistors to function. This dual-mode capability allows the LTC2960CDC-3 to interface with diverse logic families without redesigning the output stage.
Can the LTC2960CDC-3 be used to monitor both overvoltage and undervoltage conditions simultaneously?
No - the LTC2960CDC-3 variant supports only undervoltage detection on both ADJ and IN+ inputs (non-inverting configuration). For overvoltage monitoring, the LTC2960-2 or LTC2960-4 variants (IN– input) are required. The LTC2960CDC-3's IN+ input responds only to falling voltage crossings below its threshold, making it unsuitable for rising-edge OV detection without external circuitry.
What is the guaranteed minimum reset timeout period for the LTC2960CDC-3 across temperature?
The LTC2960CDC-3 has a guaranteed reset timeout period of 140ms minimum and 280ms maximum over its full operating temperature range (0°C to 70°C), with typical value at 200ms. This specification is explicitly confirmed in the Electrical Characteristics table under "tRST" parameter with "l" (full-temp-range) notation, ensuring predictable reset hold time in all commercial-environment deployments of the LTC2960CDC-3.
Is the LTC2960CDC-3 pin-compatible with other variants in the LTC2960 family?
Yes - all LTC2960 variants (including LTC2960CDC-3, LTC2960IDC-3, and LTC2960HDC-3) share identical 8-lead DFN pinout and footprint. However, pin function differs between -1/-2 and -3/-4 variants: RT pin is replaced by DVCC in LTC2960CDC-3, and output drive architecture changes accordingly. Swapping requires verifying DVCC routing and output logic configuration - mechanical compatibility exists, but electrical revalidation is mandatory.
