Product details
Overview
LTC2960HDC-1#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input voltage supervisor IC designed for multicell battery monitoring and system-level power supervision. It features 850nA quiescent current, 36V VCC operating range, ±2mV ADJ/IN+ threshold matching, and 15ms/200ms selectable reset timeout - used to generate precise reset and status signals in automotive and industrial battery systems.
For engineers reviewing the LTC2960HDC-1#TRMPBF datasheet, LTC2960HDC-1#TRMPBF pinout, LTC2960HDC-1#TRMPBF application, or LTC2960HDC-1#TRMPBF equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options - all confirmed against the official LTC2960 datasheet (2960fa) and Analog Devices product documentation.
Technical Context
The LTC2960HDC-1#TRMPBF integrates a precision 400mV internal reference with two independent comparators: one monitors the ADJ input for reset generation, while the second monitors IN+ for configurable status signaling. Its dual-threshold architecture supports both falling-edge reset (ADJ) and rising-edge status (IN+) detection with built-in hysteresis (VRHYS = 8–15mV, V+HYS = 18–25mV).
It implements a programmable reset timeout via the RT pin (GND = 15ms, VCC = 200ms), open-drain RST/OUT outputs rated to 40V, and operates across –40°C to +125°C. The device draws only 400–850nA over temperature and maintains 1.5% max threshold accuracy without external calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.5V to 36V - enables direct connection to 12V/24V/36V battery rails without external regulators. |
| Quiescent Current (ICC) | 400nA (min) to 850nA (typ) at –40°C to +125°C - preserves battery life in always-on monitoring applications. |
| Reset Threshold Accuracy | ±1.5% over temperature - ensures reliable reset assertion across automotive thermal extremes. |
| ADJ/IN+ Threshold Matching | ±2mV (max) - guarantees consistent voltage monitoring between reset and status channels. |
| Reset Timeout Options | 15ms or 200ms (RT-pin selectable) - accommodates fast microcontroller initialization or slow power-rail settling. |
| Output Type | 36V open-drain RST and OUT - allows pull-up to any logic rail ≤36V, including isolated or higher-voltage domains. |
| Operating Temperature | –40°C to +125°C (H-grade) - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
Package: 8-lead (2mm × 2mm) plastic DFN (DC8), exposed pad (optional GND connection), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Accepts 2.5V–36V; powers internal circuitry and enables UVLO protection below 1.85V. |
| RT/DVCC | Reset timeout select input | GND = 15ms timeout; VCC = 200ms timeout - no DVCC function on -1 variant. |
| RST | Reset output | Open-drain, 40V-rated; pulled low when ADJ falls below threshold; released after timeout + hysteresis recovery. |
| OUT | Status output | Open-drain, 40V-rated; pulled low when IN+ rises above threshold (rising-edge detection). |
| IN+ | Non-inverting status comparator input | Configured via resistor divider; triggers OUT on rising voltage (e.g., power-good indication). |
| ADJ | Reset threshold adjustment input | Configured via resistor divider; triggers RST on falling voltage (e.g., brown-out detection). |
| MR | Manual reset input | Pulled low to force RST low; releases after timeout - supports push-button or logic-initiated reset. |
| GND | Ground reference | Primary return path; exposed pad may be connected to PCB ground for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-current operation | 850nA typical ICC enables >10-year battery life in coin-cell–powered monitoring nodes. |
| Dual independent comparators | ADJ for reset (falling edge) + IN+ for status (rising edge) - eliminates need for separate supervisor and power-good ICs. |
| Selectable reset timeout | Hardware-configurable 15ms/200ms delay avoids firmware-based timing dependencies and improves BOM simplicity. |
| High-voltage open-drain outputs | RST/OUT rated to 40V - interfaces directly with 12V/24V logic, PLC I/O, or isolated gate drivers without level shifters. |
| –40°C to +125°C operation | H-grade qualification ensures stable performance in engine control units, battery management systems, and industrial motor drives. |
Applications
| Automotive Battery Supervision | Industrial Power-Rail Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT29D3+T | Fixed 2.93V reset threshold; no IN+/IN– status comparator; 3µA ICC; SOT23-5 package. | Single-threshold only; unsuitable for dual-event detection (e.g., low-battery + power-good). | Select when only basic reset is needed and ultra-low cost is prioritized over flexibility. |
| TPS3808G33DBVR | Fixed 3.3V reset; 1.6µA ICC; adjustable timeout (200ms default); push-pull output; no high-voltage tolerance. | Max VCC = 6.8V; cannot supervise 12V/24V rails directly; requires external level-shifting for higher voltages. | Select for low-voltage embedded systems where board space is constrained and 3.3V reset suffices. |
Compared with MAX6326UT29D3+T and TPS3808G33DBVR, the LTC2960HDC-1#TRMPBF uniquely supports dual-threshold supervision, 36V direct operation, and nano-power consumption - making it the only option capable of replacing both a reset IC and a discrete comparator in high-reliability battery systems.

FAQ
What is the maximum input voltage the LTC2960HDC-1#TRMPBF can tolerate on its VCC pin?
The LTC2960HDC-1#TRMPBF has an absolute maximum VCC rating of 40V. Operation up to 36V is specified across the full –40°C to +125°C temperature range. Transient spikes beyond 36V must be clamped externally (e.g., with Zener diodes and current-limiting resistors) to avoid exceeding the 40V absolute maximum, as confirmed in the Absolute Maximum Ratings table of the 2960fa datasheet.
Does the LTC2960HDC-1#TRMPBF support both rising- and falling-edge voltage detection?
Yes - the LTC2960HDC-1#TRMPBF supports both detection modes. Its ADJ input triggers RST on falling voltage (undervoltage detection), while its IN+ input triggers OUT on rising voltage (power-good detection). This dual-mode capability is intrinsic to the -1 variant and is explicitly documented in the Option Table and Pin Functions section of the datasheet.
How is the reset timeout period selected on the LTC2960HDC-1#TRMPBF?
The LTC2960HDC-1#TRMPBF uses the RT pin to select reset timeout: tie RT to GND for 15ms, or to VCC for 200ms. This hardware-selectable feature eliminates firmware dependency and ensures deterministic timing - a key differentiator versus software-configurable supervisors. The RT pin function is exclusive to the -1 and -2 variants.
Can the LTC2960HDC-1#TRMPBF drive a 5V logic input directly?
No - the LTC2960HDC-1#TRMPBF has open-drain RST and OUT outputs rated to 40V but no internal pull-up. To interface with 5V logic, an external pull-up resistor (e.g., 10kΩ to 5V) is required. The output will then swing from GND to 5V. This configuration is standard practice and validated in Figure 3 and Applications Information section of the datasheet.
What is the guaranteed operating temperature range for the LTC2960HDC-1#TRMPBF?
The LTC2960HDC-1#TRMPBF is rated for –40°C to +125°C ambient operation, as indicated by the "H" suffix in the part number and confirmed in the Order Information table (page 2 of 2960fa). This H-grade qualification meets AEC-Q100 stress test requirements for automotive under-hood applications and industrial high-temperature environments.
