Product details
Overview
LTC2960HDC-4#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery and automotive power monitoring. It features ADJ/IN– dual-threshold monitoring, 200ms fixed reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current, and operation from 2.5V to 36V VCC. It is used in battery disconnect circuits to prevent deep discharge in Li-ion systems.
For engineers reviewing the LTC2960HDC-4#TRMPBF datasheet, LTC2960HDC-4#TRMPBF pinout, LTC2960HDC-4#TRMPBF application, or LTC2960HDC-4#TRMPBF equivalent, this page delivers verified electrical parameters, package mapping to 8-lead DFN (2mm × 2mm), temperature-rated performance (–40°C to 125°C), and validated alternative options for brown-out detection and regulated UVLO design.
Technical Context
The LTC2960HDC-4#TRMPBF implements two independent comparators: one on ADJ (reset threshold) with 2.5% hysteresis and 400mV internal reference, and a second on IN– (inverting input) with 5% hysteresis for overvoltage detection. Its RST output asserts low when ADJ falls below threshold and releases only after both hysteresis recovery and 200ms timeout expiration.
Unlike LTC2960-1/2 variants, it replaces RT with DVCC - a dedicated logic supply pin (1.6V–5.5V) enabling active pull-up outputs that drive RST/OUT directly to DVCC, eliminating external pull-up resistors and reducing static power. Input leakage is ±0.1nA at –40°C to 85°C, supporting high-impedance divider networks.
Key Specifications

|---|---|
| VCC Operating Range | 2.5V to 36V - supports direct connection to 12V/24V automotive rails and multicell battery stacks without external regulators. |
| Quiescent Current (ICC) | 850nA max at 36V and –40°C to 125°C - enables >10-year battery life in always-on security or telematics systems. |
| Reset Threshold Accuracy | ±1.5% over –40°C to 125°C - ensures reliable brown-out detection across full automotive temperature range. |
| IN– Comparator Hysteresis | 20mV (5% of 400mV reference) - prevents chatter during slow-rising supply transients in engine start-stop cycles. |
| Reset Timeout Period | Fixed 200ms - guarantees sufficient system initialization time after power recovery before releasing RST. |
| DVCC Supply Range | 1.6V to 5.5V - allows RST/OUT logic compatibility with 1.8V, 3.3V, or 5V microcontrollers without level shifters. |
| Input Leakage (ITH(LKG)) | ±0.1nA at –40°C to 85°C - permits use of >10MΩ resistor dividers with <1% error, minimizing power loss. |
Pinout & Package
Package: 8-lead (2mm × 2mm) plastic DFN with exposed pad (pin 9), rated for –40°C to 125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main power supply input | Accepts 2.5V–36V; powers internal circuitry and enables UVLO protection below 1.85V. |
| DVCC | Logic supply for RST/OUT outputs | Defines high-level voltage for active pull-up outputs; grounding converts RST/OUT to open-drain mode. |
| RST | Reset output | Active-low, DVCC-referenced; asserts when ADJ falls below threshold and releases after 200ms + hysteresis recovery. |
| OUT | Spare comparator output | Active-low, DVCC-referenced; asserts when IN– rises above threshold (overvoltage detection). |
| IN– | Inverting threshold input | Configures overvoltage trip point via external resistor divider; referenced to 400mV internal reference. |
| ADJ | Reset threshold adjustment input | Configures primary undervoltage trip point; tied to resistor divider from monitored rail to GND. |
| MR | Manual reset input | Pull-low activates immediate RST assertion; release triggers 200ms timeout before RST release. |
| GND | Device ground reference | Common return for VCC, DVCC, inputs, and outputs; exposed pad may be connected to PCB ground. |

FAQ
What is the operating temperature range of the LTC2960HDC-4#TRMPBF?
The LTC2960HDC-4#TRMPBF is rated for –40°C to 125°C ambient operation, meeting automotive under-hood requirements. This is confirmed by its "H" grade designation in the order code and validated in the Absolute Maximum Ratings and Electrical Characteristics tables across the full range.
Does the LTC2960HDC-4#TRMPBF support active pull-up outputs?
Yes - the LTC2960HDC-4#TRMPBF uses the DVCC pin (not RT) to enable active pull-up on both RST and OUT outputs. When DVCC is connected to a 1.6V–5.5V supply, outputs drive high to DVCC; grounding DVCC reverts them to open-drain mode.
How does the IN– input function in the LTC2960HDC-4#TRMPBF?
In the LTC2960HDC-4#TRMPBF, the IN– input serves as an inverting comparator threshold. When the voltage at IN– rises above the 400mV internal reference, OUT pulls low - enabling overvoltage detection. Its 20mV hysteresis (5%) prevents noise-induced toggling during slow-rising transients.
What is the reset timeout period for the LTC2960HDC-4#TRMPBF?
The LTC2960HDC-4#TRMPBF has a fixed 200ms reset timeout period, as specified in the Option Table and Electrical Characteristics (tRST = 140ms to 280ms, typ 200ms). Unlike LTC2960-1/2 variants, it lacks an RT pin and does not support 15ms selection.
Can the LTC2960HDC-4#TRMPBF monitor two different supply rails simultaneously?
Yes - the LTC2960HDC-4#TRMPBF can monitor two rails using ADJ for primary undervoltage detection (e.g., battery pack) and IN– for secondary overvoltage detection (e.g., regulated 5V rail), enabling window supervision without additional ICs. Each input uses independent resistor dividers referenced to the same 400mV internal reference.
