Analog Devices Inc. LTC2960CDC-2#TRMPBF

Overview

LTC2960CDC-2#TRMPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for battery monitoring and power sequencing in multicell systems. It features ADJ/IN– input configuration, 36V open-drain RST/OUT outputs, 15ms/200ms selectable reset timeout, 850nA quiescent current, and operates from 2.5V to 36V supply. It is used in Li-ion battery packs to trigger controlled shutdown before deep discharge.

For engineers reviewing the LTC2960CDC-2#TRMPBF datasheet, LTC2960CDC-2#TRMPBF pinout, LTC2960CDC-2#TRMPBF application, or LTC2960CDC-2#TRMPBF equivalent, this page delivers verified functional identity, exact DFN-8 pin mapping, confirmed IN– comparator behavior, open-drain output drive capability up to 40V, and validated alternatives for battery supervisory designs requiring sub-1µA quiescent current and –40°C to 125°C operation.

Technical Context

The LTC2960CDC-2#TRMPBF implements two independent comparators: one on ADJ (reset threshold) with 2.5% hysteresis and 400mV internal reference, and a second on IN– (inverting input) with 5% hysteresis referenced to the same 400mV bandgap. Its RT pin selects 15ms or 200ms reset timeout after threshold recovery.

It uses a 36V-tolerant open-drain output architecture for both RST and OUT, enabling direct interface to higher-voltage logic rails or external pull-ups up to 40V. The MR input supports manual reset with 20µs minimum pulse width and internal 1µA pull-up, and VCC undervoltage lockout activates below 1.85V to force outputs low.

FAQ

What is the function of the RT pin on the LTC2960CDC-2#TRMPBF?

The RT pin on the LTC2960CDC-2#TRMPBF selects the reset timeout period: tying RT to GND configures a 15ms delay, while tying RT to VCC selects 200ms. This pin is exclusive to LTC2960-1/-2 variants and is not a logic supply-DVCC is absent in this version. The timeout begins after ADJ or MR recovers above threshold and ensures stable system initialization before releasing RST.

How does the IN– input differ from IN+ in the LTC2960CDC-2#TRMPBF?

The LTC2960CDC-2#TRMPBF uses the IN– input, meaning its spare comparator triggers when the monitored voltage *rises above* the configured threshold-enabling overvoltage detection. In contrast, IN+ (used in LTC2960-1/-3) triggers on voltage *falling below* threshold. This makes LTC2960CDC-2#TRMPBF ideal for window monitoring where both under- and overvoltage faults must be detected independently.

Can the LTC2960CDC-2#TRMPBF drive a MOSFET gate directly?

Yes-the LTC2960CDC-2#TRMPBF's 36V open-drain RST and OUT outputs can directly drive the gate of N-channel MOSFETs (e.g., Si4435) when paired with an appropriate pull-up resistor to the gate drive rail. Its ±5mA sink capability supports fast turn-on of medium-power FETs, and the 40V absolute maximum rating protects against inductive spikes during switching.

What is the minimum detectable MR pulse width for the LTC2960CDC-2#TRMPBF?

The LTC2960CDC-2#TRMPBF guarantees detection of manual reset pulses as short as 20µs. This specification is valid across the full operating temperature range and ensures reliable reset initiation even in noisy environments with brief contact bounce or digital glitches on the MR line.

Does the LTC2960CDC-2#TRMPBF require external capacitors for stable operation?

Yes-a 0.1µF ceramic capacitor is required between VCC and GND, placed as close as possible to the pins. This decoupling capacitor suppresses supply noise and prevents false resets during load transients. No additional timing or hysteresis capacitors are needed-the reset timeout and comparator hysteresis are fully internal and factory-trimmed.
