Analog Devices Inc. LTC2960CDC-1#TRMPBF

Overview

LTC2960CDC-1#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input voltage supervisor IC designed for battery monitoring and system reset control in multicell Li-ion, automotive, and industrial power rails. It features 850nA quiescent current, adjustable ADJ/IN+ reset thresholds, 15ms/200ms selectable reset timeout, and 36V open-drain RST/OUT outputs. It operates across 2.5V–36V supply range and supports –40°C to 85°C ambient temperature.

For engineers reviewing the LTC2960CDC-1#TRMPBF datasheet, LTC2960CDC-1#TRMPBF pinout, LTC2960CDC-1#TRMPBF application, or LTC2960CDC-1#TRMPBF equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in battery disconnect and regulator UVLO, and validated alternative options with documented functional differences.

Technical Context

The LTC2960CDC-1#TRMPBF integrates two independent comparators: one monitors the ADJ input for reset generation (with 2.5% hysteresis), and the second monitors IN+ for configurable status signaling (with 5% hysteresis). Its RT pin selects between 15ms and 200ms reset timeout periods after threshold recovery. Both RST and OUT are 36V-tolerant open-drain outputs, enabling direct interface to higher-voltage logic or external pull-ups up to 36V.

It uses an internal 400mV reference with ±2mV matching between ADJ and IN+ thresholds, and achieves 1.5% total accuracy over temperature. Input leakage is ≤±1nA at 85°C, enabling high-impedance resistive divider configurations without significant error. The device remains functional down to VCC = 2.5V and guarantees output low state for VCC ≥ 1.2V.

FAQ

What is the function of the RT pin on the LTC2960CDC-1#TRMPBF?

The RT pin on the LTC2960CDC-1#TRMPBF selects the reset timeout period: tying RT to GND configures a 15ms delay, while connecting RT to VCC sets a 200ms delay. This pin is exclusive to the -1 and -2 variants and replaces DVCC in the -3/-4 versions. The LTC2960CDC-1#TRMPBF uses this feature to provide flexible timing for MCU reset release or power-rail stabilization without changing firmware or external RC networks.

Can the LTC2960CDC-1#TRMPBF monitor two different voltages simultaneously?

Yes-the LTC2960CDC-1#TRMPBF has two independent comparator inputs: ADJ for primary reset and IN+ for secondary status monitoring. Each accepts a resistive divider to set custom thresholds. For example, ADJ can be configured for a 6.41V battery cutoff while IN+ monitors a 3.3V regulator output at 2.65V. Both thresholds reference the same internal 400mV bandgap, ensuring matched accuracy and temperature drift in the LTC2960CDC-1#TRMPBF.

What is the maximum voltage that can be applied to the RST and OUT pins of the LTC2960CDC-1#TRMPBF?

The RST and OUT pins of the LTC2960CDC-1#TRMPBF are rated for up to 40V absolute maximum and operate reliably as 36V-tolerant open-drain outputs. This allows direct connection to pull-up resistors referenced to 12V, 24V, or even 36V rails-eliminating level shifters in automotive and industrial systems. The LTC2960CDC-1#TRMPBF maintains this rating across its full –40°C to 85°C operating range without derating.

How does the LTC2960CDC-1#TRMPBF achieve 850nA quiescent current?

The LTC2960CDC-1#TRMPBF achieves 850nA typical ICC through proprietary nano-power biasing, subthreshold CMOS design, and optimized reference circuitry. Its internal 400mV bandgap operates with minimal current draw, and all comparators and timers are duty-cycled to reduce average consumption. Measured at VCC = 36V and TA = 85°C, the LTC2960CDC-1#TRMPBF sustains this ultra-low current while maintaining full functionality-including MR response, RT selection, and hysteresis-enabling decade-long operation on primary batteries.

Is the LTC2960CDC-1#TRMPBF pin-compatible with other variants like LTC2960CDC-3#TRMPBF?

No-the LTC2960CDC-1#TRMPBF is not pin-compatible with LTC2960CDC-3#TRMPBF. The -1 variant uses RT for timeout selection and has open-drain outputs, while the -3 variant replaces RT with DVCC for logic-level control and provides active pull-up outputs. Pin 2 is RT in LTC2960CDC-1#TRMPBF but DVCC in LTC2960CDC-3#TRMPBF; swapping them without board revision will cause functional failure. Always verify pin mapping using the DC8 package diagram for the specific LTC2960CDC-1#TRMPBF variant.
