Analog Devices Inc. LTC2960IDC-1#TRMPBF

Overview

LTC2960IDC-1#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input voltage supervisor IC designed for multicell battery monitoring and system reset control. It features 850nA quiescent current, 2.5V–36V VCC operating range, ±2mV ADJ/IN+ threshold matching, and 15ms/200ms selectable reset timeout. It is used in battery-powered equipment to detect falling supply voltage and assert RST/OUT for controlled shutdown or processor reset.

For engineers reviewing the LTC2960IDC-1#TRMPBF datasheet, LTC2960IDC-1#TRMPBF pinout, LTC2960IDC-1#TRMPBF application, or LTC2960IDC-1#TRMPBF equivalent, key selection criteria include its 850nA supply current, dual-threshold monitoring (ADJ + IN+), 36V open-drain outputs, –40°C to 85°C industrial temperature grade, and DFN-8 (2mm × 2mm) package with exposed pad.

Technical Context

The LTC2960IDC-1#TRMPBF integrates two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and configurable timeout, while the second monitors IN+ (non-inverting) for auxiliary voltage detection with 5% hysteresis. Its internal 400mV reference enables precise threshold setting via external resistive dividers.

It supports manual reset (MR) with 20µs minimum pulse width and 0.4V logic threshold, RT pin for 15ms/200ms timeout selection, and operates with VCC as low as 2.5V. Outputs RST and OUT are 36V-tolerant open-drain, rated for ±5mA sink current, and guaranteed functional down to VCC = 1.2V.

FAQ

What is the maximum input voltage the LTC2960IDC-1#TRMPBF can monitor on the ADJ and IN+ pins?

The ADJ and IN+ pins have an absolute maximum rating of –0.3V to 3.5V. To monitor higher voltages (e.g., 24V or 36V rails), a resistive divider must be used to scale the input down to ≤3.5V while maintaining accuracy. The LTC2960IDC-1#TRMPBF's internal 400mV reference and ±1nA input leakage enable precise scaling with standard 1% resistors up to 10MΩ.

Does the LTC2960IDC-1#TRMPBF support both rising- and falling-edge detection on its inputs?

Yes - the LTC2960IDC-1#TRMPBF provides built-in hysteresis: 2.5% on the ADJ input (e.g., 400mV threshold with 10mV hysteresis) and 5% on the IN+ input (e.g., 400mV threshold with 20mV hysteresis). This ensures clean, chatter-free transitions during supply ramp-up and ramp-down, eliminating need for external RC filtering in most applications.

Can the RST and OUT outputs of the LTC2960IDC-1#TRMPBF drive a 5V logic input directly?

No - the LTC2960IDC-1#TRMPBF has 36V open-drain outputs. To interface with 5V logic, an external pull-up resistor to 5V is required on each output. The device itself does not provide active pull-up; it sinks current only. The pull-up resistor value (e.g., 10kΩ–100kΩ) is selected based on rise-time requirements and load capacitance.

How is the reset timeout period selected on the LTC2960IDC-1#TRMPBF?

The LTC2960IDC-1#TRMPBF uses the RT pin for hardware-selectable timeout: tie RT to GND for 15ms, or to VCC for 200ms. This selection is latched at power-up and remains fixed until next VCC cycle. The timeout begins after ADJ rises above threshold or MR is released, ensuring deterministic timing without firmware involvement.

Is the LTC2960IDC-1#TRMPBF pin-compatible with other variants in the LTC2960 family?

Yes - all LTC2960 variants (e.g., LTC2960IDC-2#TRMPBF, LTC2960IDC-3#TRMPBF) share identical DFN-8 (2mm × 2mm) pinout and footprint. However, functionality differs: LTC2960IDC-1#TRMPBF uses IN+ and RT, while LTC2960IDC-2#TRMPBF uses IN– and RT, and LTC2960IDC-3#TRMPBF replaces RT with DVCC and uses active pull-up outputs. PCB layout is reusable, but schematic connections must match variant function.
