Product details
Overview
LTC2960ITS8-4#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for battery and regulator monitoring in harsh environments. It features 850nA quiescent current, 36V VCC operating range, ±2mV ADJ/IN– threshold matching, 200ms fixed reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It is used in automotive battery disconnect circuits to prevent deep discharge.
For engineers reviewing the LTC2960ITS8-4#TRMPBF datasheet, LTC2960ITS8-4#TRMPBF pinout, LTC2960ITS8-4#TRMPBF application, or LTC2960ITS8-4#TRMPBF equivalent, key selection criteria include its IN– input configuration, 200ms fixed timeout, DVCC-referenced active pull-up outputs, –40°C to 85°C temperature grade, and TSOT-23-8 package compatibility with space-constrained portable and automotive systems.
Technical Context
The LTC2960ITS8-4#TRMPBF implements dual-comparator supervision: one precision 400mV reference-based comparator on ADJ for reset generation, and a second on IN– for overvoltage detection. Its internal 200ms reset timer ensures stable release after threshold recovery, eliminating noise-induced chatter during brown-out conditions.
It supports flexible logic interfacing via DVCC (1.6V–5.5V), enabling RST and OUT to drive logic-level loads directly without external pull-ups. The IN– input allows detection of rising supply voltages-e.g., triggering shutdown when battery voltage exceeds safe limits-while ADJ monitors falling thresholds for undervoltage lockout.

FAQ
What is the function of the DVCC pin on the LTC2960ITS8-4#TRMPBF?
The DVCC pin on the LTC2960ITS8-4#TRMPBF sets the logic-high voltage level for the RST and OUT outputs. When connected to a 1.6V–5.5V supply, it enables active pull-up operation - eliminating external pull-up resistors and reducing static power. Grounding DVCC reconfigures both outputs as 36V open-drain. This flexibility allows direct interfacing with diverse logic families without additional components. The LTC2960ITS8-4#TRMPBF datasheet specifies ±50nA leakage at DVCC under these configurations.
How does the LTC2960ITS8-4#TRMPBF differ from the LTC2960-1 or LTC2960-2 variants?
The LTC2960ITS8-4#TRMPBF is the IN–/200ms/active-pull-up variant: it uses the IN– input for rising-threshold detection, has a fixed 200ms reset timeout (no RT pin), and provides DVCC-referenced RST/OUT outputs. In contrast, LTC2960-1/-2 offer selectable 15ms/200ms timeout via RT pin and 36V open-drain outputs. The "ITS8" suffix denotes TSOT-23-8 packaging and –40°C to +85°C temperature grade - confirmed in Linear's official order table for LTC2960ITS8-4#TRMPBF.
Can the LTC2960ITS8-4#TRMPBF monitor both overvoltage and undervoltage conditions simultaneously?
Yes. The LTC2960ITS8-4#TRMPBF simultaneously monitors undervoltage on the ADJ input (triggering RST low when falling below 400mV) and overvoltage on the IN– input (triggering OUT low when rising above 400mV). External resistor dividers configure each threshold independently - e.g., ADJ set to 6.0V for battery undervoltage cutoff and IN– set to 8.4V for Li-ion overvoltage protection. This dual-role capability is explicitly documented in the LTC2960ITS8-4#TRMPBF block diagram and typical application circuits.
What is the minimum recommended bypass capacitance for VCC on the LTC2960ITS8-4#TRMPBF?
The LTC2960ITS8-4#TRMPBF requires a minimum 0.01µF ceramic capacitor between VCC and GND, placed as close as possible to the pins. Linear's datasheet recommends 0.1µF for robust noise immunity in automotive or industrial environments. This capacitor stabilizes the internal reference and prevents false resets caused by supply transients - a requirement verified in the "Applications Information" section and Figure 7(a) of the LTC2960ITS8-4#TRMPBF datasheet.
Does the LTC2960ITS8-4#TRMPBF support manual reset functionality, and how is it implemented?
Yes. The LTC2960ITS8-4#TRMPBF includes a dedicated MR (Manual Reset) input that forces RST low when pulled below 0.4V. Upon release, RST remains low for the full 200ms timeout period before returning high - ensuring deterministic behavior regardless of MR pulse width. The MR pin features ±1µA internal pull-up and tolerates up to 36V, allowing direct connection to push-button switches or logic signals. This behavior is specified in the Electrical Characteristics table and Timing Diagram (Figure 5) for LTC2960ITS8-4#TRMPBF.
