Analog Devices Inc. LTC2960ITS8-3#TRMPBF

Overview

LTC2960ITS8-3#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery and regulator monitoring in space-constrained systems. It features 850nA quiescent current, 2.5V–36V VCC operating range, ±1.5% threshold accuracy over –40°C to +85°C, adjustable ADJ/IN+ reset thresholds, and fixed 200ms reset timeout. It serves as a precision brown-out detector and low-battery indicator in portable Li-ion-powered equipment.

For engineers reviewing the LTC2960ITS8-3#TRMPBF datasheet, LTC2960ITS8-3#TRMPBF pinout, LTC2960ITS8-3#TRMPBF application, or LTC2960ITS8-3#TRMPBF equivalent, key selection criteria include its TSOT-23-8 package, active pull-up RST/OUT outputs referenced to DVCC, IN+ input configuration, and compatibility with logic supplies from 1.6V to 5.5V - critical for interfacing with modern low-voltage microcontrollers and PMICs.

Technical Context

The LTC2960ITS8-3#TRMPBF integrates two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second monitors IN+ for configurable status signaling with 5% hysteresis. Its internal 400mV reference enables precise external threshold setting via resistive dividers, supporting falling-edge detection on both inputs.

Unlike the -1/-2 variants, this part replaces the RT pin with DVCC to enable logic-level-controlled active pull-up outputs; RST and OUT drive to DVCC when high and operate as open-drain when DVCC = GND. Input leakage is ≤±1nA at 85°C, ensuring minimal error in high-impedance divider networks.

FAQ

What is the maximum input voltage the ADJ and IN+ pins of the LTC2960ITS8-3#TRMPBF can tolerate?

The ADJ and IN+ pins of the LTC2960ITS8-3#TRMPBF have an absolute maximum rating of –0.3V to +3.5V. This limits the monitored voltage to ≤8.75× the programmed threshold (e.g., 3.5V/0.4V = 8.75). For a 6.0V reset threshold, the maximum safe input voltage is 52.5V. External resistive dividers must ensure the pin voltage never exceeds 3.5V under all conditions, including transients.

How does the DVCC pin affect the RST and OUT outputs of the LTC2960ITS8-3#TRMPBF?

When DVCC is connected to a 1.6V–5.5V supply, RST and OUT drive actively to that voltage when high - eliminating pull-up resistors and reducing static power. If DVCC is grounded, both outputs revert to open-drain mode and require external pull-ups to a logic-compatible voltage (≤36V). This dual-mode operation gives designers flexibility to optimize for power, speed, or voltage compatibility.

Can the LTC2960ITS8-3#TRMPBF be used to monitor a 24V automotive battery directly?

Yes - the LTC2960ITS8-3#TRMPBF supports VCC up to 36V, making it suitable for direct connection to 24V systems. To monitor battery voltage, use a resistive divider on the ADJ pin (e.g., 1MΩ + 100kΩ for ~2.18V at ADJ when VBAT = 24V). Ensure the divider current (≥0.2µA) dominates over input leakage (±0.1nA) to maintain accuracy within ±1.5%.

What is the purpose of the 200ms reset timeout in the LTC2960ITS8-3#TRMPBF, and is it adjustable?

The 200ms reset timeout in the LTC2960ITS8-3#TRMPBF ensures the RST output remains low long enough for power supplies and processors to stabilize after a brown-out event. It is fixed and non-adjustable - unlike the -1/-2 variants with selectable 15ms/200ms via the RT pin. This simplifies design for applications where consistent, predictable reset timing is required without additional control logic.

Does the LTC2960ITS8-3#TRMPBF support overvoltage detection on the IN+ input?

No - the LTC2960ITS8-3#TRMPBF's IN+ input is configured for falling-edge detection only (i.e., it asserts OUT low when the monitored voltage drops below the threshold). For overvoltage or window monitoring, the LTC2960-2 or LTC2960-4 variants with IN– input must be used, as they support rising-edge detection. The -3 variant's IN+ is strictly a low-voltage warning input.
