Analog Devices Inc. LTC2960HTS8-2#TRMPBF

Overview

LTC2960HTS8-2#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage dual-threshold voltage supervisor IC designed for battery and regulator monitoring in harsh environments. It features ADJ/IN– input configuration, 200ms fixed reset timeout, 36V open-drain RST/OUT outputs, ±2mV ADJ/IN– threshold matching, and operates from –40°C to 125°C. It is used in automotive battery disconnect circuits to prevent deep discharge.

For engineers reviewing the LTC2960HTS8-2#TRMPBF datasheet, LTC2960HTS8-2#TRMPBF pinout, LTC2960HTS8-2#TRMPBF application, or LTC2960HTS8-2#TRMPBF equivalent, key selection criteria include its 850nA quiescent current at 36V, 1.5% max threshold accuracy over temperature, IN– inverting comparator architecture, TSOT-23-8 package compatibility, and suitability for high-reliability multicell Li-ion systems requiring brown-out detection and manual reset support.

Technical Context

The LTC2960HTS8-2#TRMPBF implements two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second uses the IN– input to detect rising voltage thresholds-enabling overvoltage monitoring and controlled shutdown signaling. Its internal 400mV reference ensures stable threshold scaling across temperature.

All inputs (ADJ, IN–, MR) are referenced to GND with ±0.1nA leakage at ≤85°C and ±1nA at 125°C; outputs RST and OUT are 36V-tolerant open-drain structures rated for ±5mA sink current. The device remains functional down to VCC = 2.5V and guarantees output low state for VCC ≥ 1.2V, supporting robust operation during supply sag.

FAQ

What is the maximum input voltage rating for the ADJ and IN– pins on the LTC2960HTS8-2#TRMPBF?

The ADJ and IN– pins on the LTC2960HTS8-2#TRMPBF have an absolute maximum rating of –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. This constraint requires external resistive dividers when monitoring voltages above 8.75× the programmed threshold - for example, a 400mV internal reference limits direct sensing of supplies above 14V without attenuation. Always verify divider ratio and power dissipation per the datasheet's leakage-current error guidelines.

Does the LTC2960HTS8-2#TRMPBF support manual reset functionality, and how is it implemented?

Yes, the LTC2960HTS8-2#TRMPBF includes a dedicated MR (Manual Reset) input that accepts active-low logic signals or push-button switches. When MR is pulled below 0.4V, RST immediately goes low and remains low for the full 200ms timeout period after MR returns high. An internal 1µA pull-up current source eliminates the need for an external pull-up resistor in most cases, though a 100kΩ external pull-up is recommended if board leakage could interfere with threshold detection.

How does the IN– input differ from IN+ in the LTC2960HTS8-2#TRMPBF, and what application benefit does it provide?

The IN– input on the LTC2960HTS8-2#TRMPBF configures a rising-edge comparator: OUT pulls low when the divided input voltage crosses upward past the 400mV reference. This enables overvoltage detection - unlike IN+, which triggers on falling voltage. In battery systems, this allows the LTC2960HTS8-2#TRMPBF to simultaneously monitor undervoltage (via ADJ) and overvoltage (via IN–) with one IC, simplifying protection schemes and reducing component count versus discrete solutions.

What is the guaranteed minimum sink current capability of the RST and OUT outputs on the LTC2960HTS8-2#TRMPBF?

The RST and OUT outputs of the LTC2960HTS8-2#TRMPBF are specified to sink at least 5mA each when pulled low, with VOL ≤ 100mV at I_SINK = 500µA and VCC ≥ 3V. At lower currents (e.g., 10µA), VOL drops to ≤25mV. This ensures reliable driving of MOSFET gates, optocouplers, or logic inputs across the full –40°C to 125°C range without external buffers - critical for fail-safe shutdown paths in automotive and industrial systems.

Can the LTC2960HTS8-2#TRMPBF operate reliably during load-dump transients common in automotive 12V systems?

Yes - the LTC2960HTS8-2#TRMPBF withstands VCC transients up to 40V continuously and can survive brief spikes beyond that when protected by external clamping (e.g., Zener + series resistor per Figure 7a in the datasheet). Its 36V-rated outputs and –40°C to 125°C qualification make it suitable for direct integration into automotive battery monitoring modules. However, sustained operation above 36V on any pin violates absolute maximum ratings and requires external protection circuitry.
