Product details
Overview
LTC2960HTS8-1#TRPBF from Analog Devices (formerly Linear Technology) is a nano-power, high-voltage two-input voltage supervisor IC designed for battery and regulator monitoring in harsh environments. It features 850nA quiescent current, 2.5V–36V supply range, ±1.5% threshold accuracy over –40°C to 125°C, adjustable reset threshold via ADJ pin, and 36V open-drain RST/OUT outputs. It is used in automotive battery disconnect circuits and portable equipment brown-out protection.
For engineers reviewing the LTC2960HTS8-1#TRPBF datasheet, LTC2960HTS8-1#TRPBF pinout, LTC2960HTS8-1#TRPBF application, or LTC2960HTS8-1#TRPBF equivalent, this page delivers verified specifications, TSOT-23-8 pin mapping, thermal-rated operation up to 125°C ambient, and validated alternatives for multicell Li-ion, automotive, and industrial power supervision.
Technical Context
The LTC2960HTS8-1#TRPBF integrates two independent comparators: one monitors ADJ for reset generation with 2.5% hysteresis and selectable 15ms/200ms timeout via RT pin; the second monitors IN+ for non-inverting voltage detection with 5% hysteresis. Both inputs accept externally configured thresholds via resistive dividers, enabling custom falling/rising trip points across its full 2.5V–36V VCC range.
Its 36V open-drain outputs (RST and OUT) tolerate voltages beyond VCC and interface directly with logic supplies up to 36V. The MR input supports manual reset activation with 20µs minimum pulse width, while internal 1µA pull-up simplifies push-button integration. Absolute maximum ratings include 40V on VCC/RT/MR and 3.5V on ADJ/IN+/IN–.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 8-lead TSOT-23 (ThinSOT™), 2.9mm × 1.6mm × 0.85mm, exposed pad optional. Thermal resistance θJA = 195°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power supply input | Primary supply rail (2.5V–36V); UVLO activates below 1.85V; bypass with 0.1µF ceramic. |
| 2 - RT/DVCC | Reset timeout select / logic supply | In LTC2960-1 variant: RT selects 15ms (GND) or 200ms (VCC) timeout; not DVCC. |
| 3 - RST | Reset output | Open-drain active-low reset signal; sinks ≥5mA; requires external pull-up to logic rail ≤36V. |
| 4 - OUT | Spare comparator output | Open-drain active-low output tied to IN+ threshold; used for low-battery warning or UVLO control. |
| 5 - IN+ | Non-inverting threshold input | Configures second monitor threshold via resistor divider; 400mV reference, 5% hysteresis. |

| 8 - GND | Ground reference | Analog and digital ground; connect to system PCB ground plane; exposed pad optional. |
Key Features
| Feature | Design Value |
|---|---|
| Nano-power operation | 850nA max ICC at 125°C enables decade-long battery life in remote sensors and backup systems. |
| Dual independent comparators | ADJ for reset + IN+ for auxiliary monitoring enables simultaneous brown-out and low-battery detection. |
| 36V open-drain outputs | RST and OUT tolerate up to 40V absolute max and interface directly with 3.3V/5V/12V/24V logic rails. |
| Adjustable thresholds | Both ADJ and IN+ accept resistor dividers; supports custom trip points from ~1.2V to >30V. |
| Automotive-grade temp range | –40°C to +125°C operation meets AEC-Q100 stress test requirements for under-hood use. |
| Manual reset with timeout | MR forces RST low; release triggers same timeout period as power-up, ensuring deterministic recovery. |
Applications
| Battery Disconnect Protection | Automotive Power Supervision |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6375HUT+T | Fixed 3.08V reset threshold; 1.2µA ICC; no dual-comparator; SOT23-6 package. | Single-threshold only; lacks IN+ monitoring; unsuitable for dual-voltage or adjustable applications. | Choose only if fixed 3.08V reset suffices and board space is constrained to 6-pin footprint. |
| TPS3808G33DBVR | 3.3V fixed threshold; 1.1µA ICC; push-pull RST; no secondary comparator; SOT23-6. | No IN+ input; no adjustable threshold; incompatible with >5.5V logic rails due to push-pull output. | Select when interfacing with 3.3V MCU only and secondary monitoring is unnecessary. |
Compared with MAX6375HUT+T and TPS3808G33DBVR, the LTC2960HTS8-1#TRPBF uniquely supports fully adjustable thresholds, dual independent monitoring, 36V open-drain outputs, and automotive temperature range - making it irreplaceable for multicell battery and high-voltage industrial supervision where flexibility and ruggedness are mandatory.

FAQ
What is the maximum input voltage the ADJ and IN+ pins of the LTC2960HTS8-1#TRPBF can tolerate?
The ADJ and IN+ pins of the LTC2960HTS8-1#TRPBF have an absolute maximum rating of –0.3V to 3.5V. Exceeding 3.5V risks permanent damage. When monitoring higher voltages (e.g., 24V battery), a resistive divider must scale the input to stay within this range - for example, a 60:1 divider reduces 24V to 400mV, matching the internal reference.
Does the LTC2960HTS8-1#TRPBF support both rising and falling edge detection on the IN+ input?
No - the LTC2960HTS8-1#TRPBF IN+ input is configured for non-inverting operation and detects only falling conditions on the monitored voltage. When the divided voltage at IN+ drops below the 400mV threshold, OUT pulls low; it releases only after the voltage rises above 400mV + 20mV hysteresis (5%). Rising-edge detection is not supported on IN+.
Can the LTC2960HTS8-1#TRPBF be used with a 1.8V logic supply for its RST and OUT outputs?
Yes - the LTC2960HTS8-1#TRPBF's 36V open-drain outputs allow external pull-up to any voltage ≤36V, including 1.8V. Simply connect a pull-up resistor from RST/OUT to the 1.8V rail. Output low voltage remains ≤100mV at 500µA sink, ensuring solid logic-low compatibility with 1.8V CMOS inputs.
How does the RT pin function on the LTC2960HTS8-1#TRPBF, and what happens if it's left unconnected?
On the LTC2960HTS8-1#TRPBF, the RT pin selects reset timeout: grounded = 15ms, tied to VCC = 200ms. If left unconnected, internal leakage may cause undefined timeout behavior. The datasheet specifies RT must be actively driven - either to GND or VCC - and recommends a 100kΩ pull-down if 15ms is desired and no external control is needed.
Is the LTC2960HTS8-1#TRPBF pin-compatible with other variants like LTC2960HTS8-2#TRPBF?
No - LTC2960HTS8-1#TRPBF and LTC2960HTS8-2#TRPBF share the same TSOT-23-8 package and pinout, but differ functionally: LTC2960HTS8-1#TRPBF uses IN+ for the spare comparator, while LTC2960HTS8-2#TRPBF uses IN–. Swapping them without circuit revision will invert the secondary monitoring logic and likely cause malfunction.
