Analog Devices Inc. LTC2960HDC-1#TRPBF

Overview

LTC2960HDC-1#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage dual-threshold voltage supervisor IC designed for multicell battery monitoring and system-level power supervision. It features an adjustable ADJ-input reset threshold (400 mV typ), 15 ms / 200 ms selectable reset timeout, 36 V open-drain RST/OUT outputs, and operates from 2.5 V to 36 V with only 850 nA quiescent current. It is used in automotive battery management systems to detect undervoltage conditions before deep discharge.

For engineers reviewing the LTC2960HDC-1#TRPBF datasheet, LTC2960HDC-1#TRPBF pinout, LTC2960HDC-1#TRPBF application, or LTC2960HDC-1#TRPBF equivalent, key selection criteria include its –40°C to 125°C operating temperature range, 1.5% max threshold accuracy over temperature, IN+ input configuration, RT pin-based timeout selection, and compatibility with high-side sensing in 36 V battery stacks.

Technical Context

The LTC2960HDC-1#TRPBF integrates two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis, while the second monitors IN+ for auxiliary status signaling with 5% hysteresis. Its internal 400 mV reference enables precise threshold setting via external resistive dividers across input voltages up to 36 V.

It uses an open-drain output architecture rated to 40 V absolute maximum, supporting pull-up to any logic or supply rail ≤36 V. The RT pin selects between 15 ms and 200 ms reset timeout periods, and MR provides asynchronous manual reset activation with sub-20 µs propagation delay.

FAQ

What is the maximum input voltage the ADJ and IN+ pins of the LTC2960HDC-1#TRPBF can tolerate?

The ADJ and IN+ pins of the LTC2960HDC-1#TRPBF have an absolute maximum rating of –0.3 V to 3.5 V. Exceeding 3.5 V risks permanent damage. To monitor higher voltages (e.g., 24 V or 36 V), external resistive dividers must scale the input down to ≤3.5 V while maintaining ≥0.4 V at the pin for valid comparison. The LTC2960HDC-1#TRPBF datasheet specifies that the lowest programmed threshold must be >17 V for a 150 V input to satisfy this constraint.

How does the RT pin affect reset timing in the LTC2960HDC-1#TRPBF?

The RT pin on the LTC2960HDC-1#TRPBF selects between two factory-trimmed reset timeout periods: tying RT to GND configures a 15 ms timeout, while tying RT to VCC selects 200 ms. This timeout begins after the ADJ input rises above threshold (plus hysteresis) or after MR is released. The LTC2960HDC-1#TRPBF guarantees tRST tolerance of ±40% over temperature, with typical values of 140–280 ms for the 200 ms option.

Can the LTC2960HDC-1#TRPBF drive a MOSFET gate directly?

Yes - the LTC2960HDC-1#TRPBF's 36 V open-drain RST and OUT outputs can directly drive the gate of high-side N-channel MOSFETs (e.g., Si4435) when pulled up to a voltage ≤36 V. With 5 mA sink capability and <100 mV VOL at 500 µA, it ensures strong turn-on of logic-level FETs. For standard-level FETs requiring >4.5 V V_GS, a pull-up to ≥5 V is required, which the LTC2960HDC-1#TRPBF supports safely.

What is the purpose of the exposed pad on the LTC2960HDC-1#TRPBF DFN package?

The exposed pad (pin 9) on the LTC2960HDC-1#TRPBF's 2 mm × 2 mm DFN package serves as a thermal and electrical connection point. It may be left floating or soldered to PCB ground to reduce θ_JA from 80.6°C/W to ~60°C/W, improving thermal performance in high-ambient environments like automotive under-hood applications. No electrical function is assigned to the pad beyond optional grounding.

Does the LTC2960HDC-1#TRPBF support operation with VCC below 2.5 V?

No - the LTC2960HDC-1#TRPBF requires VCC ≥2.5 V for guaranteed operation per its Electrical Characteristics table. Below 2.5 V, internal circuitry may become unstable; outputs are not specified, and the device enters undefined behavior. At VCC <1.2 V, RST and OUT are actively pulled low regardless of input state, but this is a fail-safe condition, not functional operation. The LTC2960HDC-1#TRPBF must be powered within its 2.5 V–36 V range to perform supervision.
