Analog Devices Inc. LTC2960HDC-4#TRPBF

Overview

LTC2960HDC-4#TRPBF from Analog Devices (formerly Linear Technology) is a nano-current, high-voltage two-input voltage supervisor IC designed for multicell battery and automotive power monitoring. It features ADJ/IN– dual-threshold configuration, 200ms fixed reset timeout, active pull-up RST/OUT outputs referenced to DVCC, 850nA quiescent current at 36V, and operation from –40°C to 125°C. It is used in Li-ion battery protection circuits to trigger controlled shutdown before deep discharge.

For engineers reviewing the LTC2960HDC-4#TRPBF datasheet, LTC2960HDC-4#TRPBF pinout, LTC2960HDC-4#TRPBF application, or LTC2960HDC-4#TRPBF equivalent, key selection criteria include its IN– comparator architecture for overvoltage detection, DVCC-referenced active pull-up outputs enabling logic-level compatibility with 1.6V–5.5V controllers, and guaranteed 1.5% threshold accuracy across extended temperature.

Technical Context

The LTC2960HDC-4#TRPBF implements two independent comparators: one on the ADJ input (reset function, 400mV internal reference) and one on the IN– input (spare monitor, also 400mV reference), both with built-in hysteresis (VRHYS = 10mV typ, V–HYS = 20mV typ). Its reset timeout is fixed at 200ms and non-selectable, distinguishing it from RT-pin variants.

It uses an active pull-up output stage driven by DVCC (1.6V–5.5V), eliminating external pull-up resistors and reducing static power dissipation. When DVCC = GND, RST and OUT revert to open-drain operation. The device guarantees RST low state for VCC ≥ 1.2V and includes UVLO (1.85V–2.3V) to ensure predictable behavior during brownout.

FAQ

What is the function of the DVCC pin on the LTC2960HDC-4#TRPBF?

The DVCC pin on the LTC2960HDC-4#TRPBF serves as the logic supply reference for the RST and OUT outputs. When connected to 1.6V–5.5V, it enables active pull-up operation with VOH = 0.7×DVCC. Grounding DVCC reconfigures both outputs as open-drain. This flexibility allows the LTC2960HDC-4#TRPBF to interface directly with diverse MCU I/O voltages without external level-shifting components.

How does the LTC2960HDC-4#TRPBF differ from the LTC2960-1 or LTC2960-2 variants?

The LTC2960HDC-4#TRPBF is the high-temperature (–40°C to 125°C), IN–/ADJ configured, fixed 200ms timeout, active pull-up output variant. Unlike LTC2960-1/-2, it lacks the RT pin (replaced by DVCC) and does not support selectable 15ms/200ms timeout. Its IN– input enables overvoltage detection, whereas LTC2960-1 uses IN+ for undervoltage detection. All share the same DFN-8 package and nano-power architecture.

Can the LTC2960HDC-4#TRPBF monitor voltages above 36V?

No-the LTC2960HDC-4#TRPBF has an absolute maximum VCC rating of 40V and an operating range of 2.5V–36V. To supervise higher voltages (e.g., 48V or 72V systems), external resistive dividers must scale the input down to ≤36V at VCC, and the ADJ/IN– inputs (max 3.5V) must be protected with clamping or attenuation networks per the datasheet's high-voltage transient guidance.

What is the minimum pulse width the MR input can detect on the LTC2960HDC-4#TRPBF?

The MR input on the LTC2960HDC-4#TRPBF reliably detects logic-low pulses as short as 20µs (minimum specified tPW). This allows use with fast microcontroller GPIOs or debounce-free mechanical switches. The internal 1µA pull-up ensures MR remains high when floating, and leakage current is limited to ±1µA over temperature, minimizing false triggering in noisy environments.

Does the LTC2960HDC-4#TRPBF provide hysteresis on both comparator inputs?

Yes-the LTC2960HDC-4#TRPBF provides built-in hysteresis on all monitored inputs: VRHYS = 10mV (typ) on ADJ, V–HYS = 20mV (typ) on IN–, and V+HYS = 20mV (typ) on IN+. This hysteresis-equivalent to ~2.5%–5% of the 400mV internal reference-prevents output chatter during slow-moving or noisy supply transitions, a critical feature for battery voltage monitoring where thresholds must remain stable across discharge curves.
