Analog Devices Inc. LTC2960HTS8-2#TRPBF

Overview

LTC2960HTS8-2#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, 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, and operates from 2.5V to 36V with only 850nA quiescent current. It is used in automotive battery disconnect circuits to prevent deep discharge.

For engineers reviewing the LTC2960HTS8-2#TRPBF datasheet, LTC2960HTS8-2#TRPBF pinout, LTC2960HTS8-2#TRPBF application, or LTC2960HTS8-2#TRPBF equivalent, key selection criteria include its –40°C to 125°C operating range, IN– comparator architecture for overvoltage detection, 1.5% threshold accuracy over temperature, and TSOT-23-8 package compatibility with space-constrained automotive and industrial PCBs.

Technical Context

The LTC2960HTS8-2#TRPBF implements two independent comparators: one on ADJ (reset threshold) and one on IN– (inverting input), enabling simultaneous undervoltage and overvoltage monitoring. Its internal 400mV reference and ±2mV threshold matching ensure precise voltage supervision across temperature.

It uses a fixed 200ms reset timeout period and delivers 36V-tolerant open-drain outputs without requiring DVCC-unlike LTC2960-3/4 variants-making it suitable for direct interface with high-side FET gate drivers or 24V logic systems without level-shifting.

FAQ

What is the maximum input voltage the LTC2960HTS8-2#TRPBF can monitor on the ADJ and IN– pins?

The ADJ and IN– pins of the LTC2960HTS8-2#TRPBF have an absolute maximum rating of –0.3V to 3.5V. To monitor higher voltages (e.g., 12V, 24V), external resistive dividers must scale the input down to ≤3.5V while maintaining sufficient divider current (>0.2µA) to minimize leakage-induced error. The LTC2960HTS8-2#TRPBF itself does not include internal scaling.

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

Yes, the LTC2960HTS8-2#TRPBF includes a dedicated MR (Manual Reset) input. Pulling MR low forces the RST output low immediately, and RST remains low for the full 200ms reset timeout period after MR returns high. The MR pin has a 0.4V logic threshold and draws <1µA, allowing direct interface with pushbuttons or microcontroller GPIOs without external pull-up resistors.

How does the LTC2960HTS8-2#TRPBF differ from the LTC2960HTS8-1#TRPBF variant?

The LTC2960HTS8-2#TRPBF uses the IN– input for its spare comparator (enabling overvoltage detection), while the LTC2960HTS8-1#TRPBF uses IN+. Both share the same 200ms fixed timeout and 36V open-drain outputs. The pinout is identical, but the internal comparator polarity differs-requiring different resistor divider topologies for threshold configuration.

Can the RST and OUT outputs of the LTC2960HTS8-2#TRPBF drive MOSFET gates directly?

Yes-the 36V open-drain RST and OUT outputs of the LTC2960HTS8-2#TRPBF can directly drive the gates of N-channel MOSFETs (e.g., Si4435) when pulled up to a suitable voltage (e.g., 12V or 24V). Each output supports ±5mA sink current, sufficient for typical gate charge requirements in battery disconnect applications without external drivers.

What is the purpose of the exposed pad on the TSOT-23 package of the LTC2960HTS8-2#TRPBF?

The exposed pad on the LTC2960HTS8-2#TRPBF's TSOT-23 package is optional and may be left floating or connected to GND. Unlike DFN packages, the TSOT-23 exposed pad does not serve as a thermal or electrical enhancement path; it is not internally connected to any die node and has no functional impact on electrical performance or thermal dissipation.
