Product details
Overview
LTC2960HTS8-3 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 harsh environments. It features 850nA quiescent current, 2.5V–36V VCC operating range, ±2mV ADJ/IN+ threshold matching, fixed 200ms reset timeout, and active pull-up RST/OUT outputs referenced to DVCC. It is used in automotive battery disconnect circuits and portable equipment brown-out protection.
For engineers reviewing the LTC2960HTS8-3 datasheet, LTC2960HTS8-3 pinout, LTC2960HTS8-3 application, or LTC2960HTS8-3 equivalent, key selection criteria include its 200ms fixed timeout, IN+/ADJ dual-threshold configuration, TSOT-23-8 package with exposed pad, –40°C to 125°C operation, and DVCC-referenced push-pull output logic - critical for low-power microcontroller reset integrity and battery voltage sequencing.
Technical Context
The LTC2960HTS8-3 implements two independent comparators: one monitors the ADJ input for reset generation with 2.5% hysteresis and 200ms timeout, while the second monitors IN+ for configurable status signaling with 5% hysteresis. Its internal 400mV reference enables precise threshold setting via external resistive dividers across inputs ADJ and IN+.
Unlike variants with RT pin or open-drain outputs, the LTC2960HTS8-3 replaces RT with DVCC to support logic-level programmable output swing (1.6V–5.5V), enabling direct interface with low-voltage MCUs without external pull-ups. Its 850nA supply current at 36V and guaranteed operation down to VCC = 1.2V ensure reliability in deep-battery-discharge scenarios.
Key Specifications

Pinout & Package
Package: TSOT-23-8 (ThinSOT™), 8-lead plastic, 2.9mm × 1.6mm footprint, exposed pad (pin 8) recommended for thermal and electrical grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main power supply input | Accepts 2.5V–36V; undervoltage lockout activates below 1.85V; bypass with 0.1µF capacitor required. |
| DVCC | Logic supply reference for RST/OUT | Sets output high level (0.7×DVCC min); grounding enables open-drain mode; must be 1.6V–5.5V when active. |
| RST | Reset output | Active-low reset signal with 200ms timeout; driven to DVCC when high; sinks ≤100µA when low. |
| OUT | Secondary status output | Monitors IN+; asserts low on threshold breach; same drive characteristics as RST; used for NMI or controlled shutdown. |
| IN+ | Non-inverting comparator input | Configures second threshold (e.g., low-battery warning); requires resistive divider; max input voltage 3.5V. |
| ADJ | Reset threshold adjustment input | Primary reset trigger point; tied to resistor divider; 400mV internal reference; ±2mV matching to IN+. |
| MR | Manual reset input | Pull to GND to force RST low; 0.4V logic threshold; supports push-button or MCU GPIO assertion. |
| GND | Device ground reference | Common return for VCC, DVCC, and all signals; exposed pad (pin 8) should be connected to PCB ground plane. |

Use Value: 850nA quiescent current extends usable battery life by >30% versus µA-class supervisors; TSOT-23-8 footprint minimizes PCB area in space-constrained designs. | Use Scenario: Supervising 12V vehicle battery voltage to detect cranking dips, alternator failure, or parasitic drain. IC Role / Device Role / Timing Role: LTC2960HTS8-3 monitors battery via ADJ for cold-crank UVLO (e.g., 6.5V) and IN+ for low-voltage warning (e.g., 10.5V), driving separate fault indicators. Use Value: –40°C to 125°C rating ensures functionality during extreme ambient conditions; 36V VCC tolerance handles load-dump transients without external clamping. |
| Industrial Power Sequencing | Security System Backup Power |
Use Scenario: Controlling startup order of multiple DC/DC converters in programmable logic controllers or motor drives. IC Role / Device Role / Timing Role: LTC2960HTS8-3 uses ADJ to monitor main 24V rail and IN+ to verify auxiliary 5V rail; RST enables master controller only after both are stable.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326US29D3+T | Single-input, fixed 2.93V reset threshold; 3µA ICC; SOT23-3 package; no secondary comparator or DVCC option. | Only suitable for basic reset-only use cases; cannot replicate dual-threshold monitoring or low-power sequencing of LTC2960HTS8-3. | Select when cost-sensitive, single-threshold reset suffices and board space is extremely constrained. |
| TPS389033DSER | Single-input, adjustable threshold via external resistor; 250nA ICC; 1.8V–6V VCC; no IN+/ADJ dual-input capability; open-drain outputs only. | Lacks second comparator and DVCC-referenced push-pull outputs; requires external pull-ups; limited to low-voltage systems. | Choose for ultra-low-ICC (<300nA) in sub-6V systems where dual monitoring is unnecessary. |
Compared with MAX6326US29D3+T and TPS389033DSER, the LTC2960HTS8-3 uniquely delivers dual-threshold supervision, DVCC-configurable logic levels, and 36V operation in a single TSOT-23-8 package - making it the only option capable of replacing discrete supervisor + comparator solutions in high-voltage, low-power, multi-rail systems.

FAQ
What is the maximum input voltage the LTC2960HTS8-3 can tolerate on its ADJ, IN+, and IN– pins?
The LTC2960HTS8-3 specifies an absolute maximum input voltage of –0.3V to 3.5V on ADJ and IN+ pins. Exceeding 3.5V risks permanent damage. This limit necessitates external resistive dividers when monitoring voltages above 8.75× the programmed threshold - for example, a 6V threshold requires limiting input to ≤26.25V. Always verify divider ratio and transient margin per the Absolute Maximum Ratings table.
Can the LTC2960HTS8-3 operate with VCC below 2.5V?
The LTC2960HTS8-3 has a specified minimum VCC of 2.5V for normal operation per Electrical Characteristics. However, the device guarantees RST remains low down to VCC = 1.2V, providing fail-safe behavior during deep brown-out. Below 2.5V, comparator accuracy, timeout timing, and DVCC-referenced output levels are not guaranteed - so functional operation is only assured within the 2.5V–36V range.
How does the DVCC pin affect the RST and OUT outputs of the LTC2960HTS8-3?
When DVCC is connected to a 1.6V–5.5V supply, RST and OUT become active pull-up outputs driven to DVCC logic high; when DVCC is grounded, both outputs revert to 36V-tolerant open-drain mode requiring external pull-ups. This dual-mode flexibility allows the LTC2960HTS8-3 to interface directly with 1.8V/3.3V MCUs or withstand higher-voltage bus signaling - all without changing the PCB layout.
Is the LTC2960HTS8-3 pin-compatible with other variants like LTC2960HTS8-1 or LTC2960HTS8-2?
No - the LTC2960HTS8-3 is not pin-compatible with LTC2960HTS8-1 or LTC2960HTS8-2. The LTC2960HTS8-3 replaces the RT pin (used for timeout selection in -1/-2) with DVCC (logic supply reference). Swapping packages without redesigning the DVCC connection and output pull-up strategy will cause functional failure. Always verify pin mapping against the specific variant's datasheet.
What is the purpose of the exposed pad on the TSOT-23-8 package of the LTC2960HTS8-3?
The exposed pad (pin 8) on the LTC2960HTS8-3 TSOT-23-8 package serves as a thermal and electrical connection point. While optional per datasheet, connecting it to the PCB ground plane significantly improves thermal dissipation (reducing θJA from 195°C/W to ~120°C/W) and lowers ground impedance - critical for noise immunity in high-voltage monitoring applications. It must not be left floating in production designs.
