Analog Devices Inc. LTC2960IDC-2#TRMPBF

Overview

LTC2960IDC-2#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery monitoring and power-rail supervision in harsh environments. It features 850nA quiescent current, ±1.5% threshold accuracy over –40°C to 85°C, adjustable ADJ/IN– reset thresholds via external resistive dividers, and 36V open-drain RST/OUT outputs. It is used in automotive battery disconnect circuits and portable equipment brown-out protection.

For engineers reviewing the LTC2960IDC-2#TRMPBF datasheet, LTC2960IDC-2#TRMPBF pinout, LTC2960IDC-2#TRMPBF application, or LTC2960IDC-2#TRMPBF equivalent, key selection criteria include its IN– input configuration, 15ms/200ms selectable reset timeout, 36V open-drain output capability, and operation across 2.5V–36V VCC with ultra-low ICC.

Technical Context

The LTC2960IDC-2#TRMPBF implements dual-comparator architecture: one dedicated ADJ input for reset generation with 2.5% hysteresis and a second IN– input configured for overvoltage detection (output pulls low when IN– rises above threshold). Its RT pin selects between 15ms and 200ms reset timeout periods, enabling flexible system initialization timing.

It operates with 36V-tolerant open-drain RST and OUT outputs, allowing pull-up to voltages exceeding VCC-critical for interfacing with higher-voltage logic or driving external MOSFET gates. The MR input supports manual reset activation with 20µs minimum pulse width and internal 1µA pull-up.

FAQ

What is the function of the RT pin on the LTC2960IDC-2#TRMPBF?

The RT pin on the LTC2960IDC-2#TRMPBF selects the reset timeout period: tied to GND for 15ms, tied to VCC for 200ms. This hardware-selectable delay ensures stable system startup after power recovery or manual reset, eliminating reliance on software timing or external RC networks. The LTC2960IDC-2#TRMPBF uses this pin instead of DVCC, distinguishing it from -3/-4 variants.

How does the IN– input differ from ADJ in the LTC2960IDC-2#TRMPBF?

The ADJ input on the LTC2960IDC-2#TRMPBF triggers RST low when voltage falls below threshold (brown-out detection), while the IN– input triggers OUT low when voltage rises above threshold (overvoltage detection). Both reference the same 400mV internal comparator, but IN– implements rising-edge logic with 20mV hysteresis. This dual-mode capability is intrinsic to the LTC2960IDC-2#TRMPBF variant.

Can the LTC2960IDC-2#TRMPBF drive a MOSFET gate directly?

Yes-the 36V open-drain RST and OUT outputs of the LTC2960IDC-2#TRMPBF can directly drive the gate of a high-side N-channel MOSFET when pulled up to an appropriate voltage (e.g., 12V) via an external resistor. No level shifter is needed, and the 5mA output sink capability ensures robust turn-on. This functionality is confirmed in Figure 10 of the LTC2960 datasheet for the LTC2960IDC-2#TRMPBF.

What is the minimum VCC required for guaranteed RST output behavior in the LTC2960IDC-2#TRMPBF?

The LTC2960IDC-2#TRMPBF guarantees RST output behavior down to VCC = 1.2V. Below this voltage, output states are not assured-even with DVCC grounded or external pull-ups. This specification is explicitly stated in the Pin Functions section and Absolute Maximum Ratings table for the LTC2960IDC-2#TRMPBF, ensuring predictable reset hold during deep brown-out conditions.

Is the LTC2960IDC-2#TRMPBF pin-compatible with other LTC2960 variants?

No-the LTC2960IDC-2#TRMPBF is not pin-compatible with LTC2960-3 or LTC2960-4 variants because RT replaces DVCC in the pinout. While both share the same DC8 package footprint and pin positions for VCC, GND, RST, OUT, ADJ, IN–, and MR, the RT pin (Pin 2) serves a different function than DVCC (Pin 2 on -3/-4), making direct substitution electrically invalid without board revision.
